	Cesspools The wastewater collected in cesspools is transported to communal wastewater processing plants, and no nutrient load is placed on surrounding natural water systems. Quite often the toilet water is to be collected in a cesspool, because a major part of the nutrients (70-80 %) loading the environment originates from toilet waters. The cesspool is ideal for important ground water areas, and for other areas, where even the processed wastewater cannot be led into the soil. Depending on the application, even a small cesspool can be sufficient. In some cases, however, it is essential to purchase a cesspool with the volume of several cubic metres. Wavin-Labko has a wide range of PE and GRP cesspools in different sizes. All the cesspools of Wavin-Labko are equipped with filling alarms that comply with the requirements. Advantages of Wavin-Labko’s Cesspools: • Cesspools are low (depending on the size, from lower edge of the inlet sewer to the bottom 1 m-1.57 m). • Labko Cesspools have no restrictions on installation due to ground water level. • The cesspools made of strong PE plastic have the emptying pipe in the middle of the tank. In addition to the ball-shape of the bottom, this allows the complete emptying of the tank. • The maximum installation depth of the Labko Cesspools is one metre from the lower edge of the inlet sewer to the ground surface. • The GRP Cesspool is also available with extra-reinforced wall. This is suitable in locations, where the sewer depth exceeds one metre – even up to the 80 000 litre volume. Complete equipment set is delivered with each cesspool. This includes the LOKASET 20 filling alarm, the probe with 15 m cable, the anchoring belts, and the emptying pipe with the cap. The alarm device contributes to an easy way of controlling the filling of the cesspool. Labko LOKA 10000 Cesspool is delivered either with the emptying pipe (D 200) or with the maintenance shaft (D 600). The maintenance shaft has a plastic cover. Anchoring plates are available as an accessory. Infiltration systems An Infiltration System is an underground wastewater processing system with a septic tank as the pre-processing unit. In the septic tank the components heavier and lighter than water are separated from the wastewater. From the septic tank the solid-free wastewater is led into the subsoil infiltration pipes. A biologically active layer forms in the soil, where the microorganisms decompose the main part of the organic matter in the wastewater. The cleaned wastewater infiltrates into the ground. A two-chamber septic tank is sufficient for processing the grey wastewaters, whereas a 3-chamber septic tank is designed to process all wastewaters. Labko SAKO Septic Tanks are designed according to the EN-12566-1 standard. Labko SAKO systems are ready-to-install packages for constructing a subsoil processing system. Labko SAKO-3 Infiltration System includes the septic tank and the infiltration pipes with filtration fabric. In many tanks there is an in-built, patented flow divider, which allows an equal flow into both infiltration pipelines. DeLuxe and Tripla models include a separate distribution well. When the distribution well is used, the subsoil processing system can be located further apart from the Labko SAKO tank, and the aligned position is not the only option to lay the infiltration pipes. This might be needed, e.g. when the soil beneath the building is not suitable for infiltration, or when the building stands on sloped terrain, and the infiltration pipes are aligned with the contours. Labko SAKO System Advantages • Special-perforated infiltration pipes • Covers of the maintenance shafts can be locked • Easily hidden from the eye, since the maintenance shafts can be cut to align with the surrounding ground level (400-1000 mm) • Shallow structure (bottom-inlet 1170 mm), suitable for sites with rock close to the ground surface • The ball-shape of the septic tank bottom and the spacious maintenance shaft allow complete emptying • High maintenance shaft allows sewer installation even in 1 metre depth Pipes and chambers Pipes and chambers Separator Systems When developing the separator systems of Wavin-Labko, we have used our experience of more than 40 years in manufacturing various separators. The separators are manufactured in Finland, in the plastic factories of Wavin-Labko. All products are tested and reliable, whole systems ready to be installed, including the separator, a maintenance shaft dimensioned according to the installation area, and a cast iron cover and frame set. All oil separators of Wavin-Labko also include the oil filling alarm device as a standard. Reliable and Durable Products The separators of Wavin-Labko are operationally reliable, and special attention has been paid on their easy maintenance. High quality and consideration for the facts of environmental protection ensure that the user can have the best possible result for decades to come. Wavin-Labko’s separators are made of PE or GRP plastic. Due to the solid and recyclable PE plastic, the separators are light to transport and quick to install. The GRP separators are manufactured using a computer operated winding machine, and their strength is far superior e.g. to those laminated by hand. PE and GRP plastic are materials immune to corrosion, and their chemical resistance is overwhelming e.g. compared to the concrete separators. Tested Models Wastewater emission is controlled more and more strictly by increasingly stringent legislation. Wavin-Labko is ready to comply with the requirements, having developed a series of separators, which has passed the tests according to the EN standard defining the flow rate and purification efficiency. When tested, the 1st class separators are to reach a hydrocarbon concentration of less than 5 mg/l in the outflowing wastewater, and correspondingly, the 2nd class separators should have a concentration of less than 100mg/l. The mechanical ground pressure resistance of the maintenance shafts is also ensured by tests according to the EN 1825 standards. Sequence Batch Reactors BioKem Batch Reactors are biological-chemical wastewater treatment plants, into which all the wastewater from a residence can be led. They are intended as effluent treatment systems for residences used all year round in rural or sparsely populated areas. BioKem Batch Reactor consists of the underground process tank, maintenance shaft and device shelter. The chemical pump, the compressor and the chemical canister are located in the device shelter. Additionally, it contains the control unit, which controls the process. The device shelter is placed next to the process tank on the ground surface. The tank itself is emptied of the residual sludge from 2 to 4 times a year, according to the model. Desludging is done clean and easy using an emptying truck. BioKem Batch Reactor is ideal for challenging installation sites, too. The tank is small and durable, and the maintenance shaft of the tank has a terrain-adaptive and childproof cover, which can be locked. The delivery includes starting chemicals, according to the model. BioKem is a low-cost solution. In addition to the low price, the low power consumption and the long emptying cycle make BioKem inexpensive to use. Advantages of BioKem Batch Reactor: • Easy to maintain • Low-cost in use • Easy and quick to install • Meets the requirements of the wastewater standards • Simple process • Odourless • Durable and long-lasting Wastewater Treatment Systems Wavin-Labko offers the widest product family of Wastewater Treatment Systems in Rural Areas in Finland. Wavin-Labko presents the best possible wastewater treatment solution, according to the needs of each residence or summer cottage. Purchasing a new wastewater system, or renovating the old, is always a significant financial effort. Wavin-Labko values the fact that the customers can rely on the quality of the products, even in demanding conditions, through the whole wastewater system range.

	Combination suction flushing vehicle Versatility in cleaning, collection, and transport of many sided disposal operations The use of combination suction flushing vehicles in sewer cleaning operations is on the increase. These vehicles can also be used when when required to transport controlled substances, as well as liquid waste materials which require monitoring to GGVS/ADR regulations (Hazardous goods) Disposal technology Disposal technology is easily the largest department at the company MÜLLER. Due to the many sided disposal operations in sewer cleaning, such as road drain cleaning, cesspit and tank emptying, petrol and oil separation cleaning, as well as the disposal of hazardous materials, the liquid waste disposal vehicles manufactured by Müller are, as a rule not standard, but built to individual customer requirements, taking into consideration proven fittings, and requirements in power, size , and equipment. Since the foundation of the company, over 4000 vehicles have been manufactured and delivered resulting from national, and international inquiries. The Müller system of production benefits from a high percentage of self developed compatable fittings, profitable to the customer due to the constant manufacturing quality, and long term availability of spare parts. Decades of operation, and production experience in liquid waste technology, and the consequent orientation to customer requirements, have resulted in MÜLLER Umwelttechnik's high standard of competence in this specialist branch, indispensible in the manufacture of liquid waste disposal vehicles Faecal and industrial sludge disposal vehicle (DRAINMASTER) for de-watering, and performance orientated disposal of faecal and industrial sludges with water recycling Based on a standard suction pressure vehicle, MÜLLER is now able to present the second generation of the DRAINMASTER as a mobil sludge de-watering and disposal vehicle, which can also be used as standard sludge disposal vehicle. The DRAINMASTER-specific configuration consists of a polymer conditioning unit and a MaskoZoll®-de-watering unit from our Norwegian partner ALTINEX, located to the side of the cylindrical three chamber tank. An adjustable partition wall (pneumatic piston) divides the tank into two compartments for the collected sludge as well as for the de-watered sludge. While suction of the raw sludge into the tank is in operation, a prepared polymer solution is added automatically by means of the polymer unit. This respectively enables and improves the de-watering process. The pre-processed sludge is then fed into the de-watering unit. The separated filtrate water can then be discharged via a filtrate tank into drainage sewers, septic tanks, fatty grease traps, or likewise, thus avoiding transport and disposal of this filtrate water. The de-watered sludge is fed into the sludge chamber of the cylindrical tank. This results in the vehicle being able, to collect sludge from several sites, the amount depending on the size and volume of the tank. The pneumatic piston allows easy emptying of the sludge chamber. A small high pressure flushing unit is fitted an can be used to clean drainage sewers, shafts, and pipes while sludge collection is in operation. High pressure flushing vehicle (JETMASTER) High pressure flushing vehicle (JETMASTER) für for economical pipeline, sewer, and industrial cleaning Modern day sewer, and pipeline cleaning as basic measures (maintenance) of sewer upkeep, is unthinkable without flushing vehicles.

	EuroSchacht aus EuroCrete Der 12h-Polymerbetonschacht mit dem Handling-Vorteil Das Standardprogramm - Felix, Paul und Max Die Systemschächte aus EuroCrete in den Nennweiten DN 1000 (Felix), DN 1200 (Paul) und DN 1500 (Max) bilden das Standardprogramm. Sie sind einschließlich der Anschlusskonstruktionen vom Deutschen Institut für Bautechnik unter der Nummer Z-42.1-353 zugelassen. In einer neuen Fertigungsmethode werden die Schachtsockel einschließlich der gewünschten Einbindungen aus EuroCrete hergestellt; die auskragende Bodenplatte dient der Auftriebssicherung. Danach folgt der Ausbau: Auf einem harzgebundenen Leichtbeton-Profil wird die Auskleidung (Auftritt und Gerinne) als EuroCrete-Estrich aufgebracht. Die Arbeitgsfuge zwischen Schachtsockel und aufsteigendem Schachtrohr wird werkseitig mit 2-Komponenten Epoxi-Reaktionsharz geschlossen, so dass ein einteiliger monolithischer Schacht entsteht. Schachtrohre werden in Fertigungslängen von drei Metern gegossen und erst nach Endreaktion entschalt. Die so entstehenden maßhaltigen und kreisrunden Schachtrohre werden individuell zugeschnitten und mit Steigeisen versehen. EuroCrete – Der Werkstoff Die Werkstoffeigenschaften sind Grundlage für die Leistungsfähigkeit des Schachtsystems. EuroCrete besteht aus Polyester-Reaktionsharz (DIN 16946-Teil 2, Typ 1140) als Bindemittel und aus einem optimal abgestimmten Kies-Sand-Zuschlag. Der geschlossene, porenarme Werkstoff ist wasserdicht und gegenüber Gas diffusionsdicht. Die Werkstoff-Qualität der Schachtrohre aus EuroCrete ist in DIN 54815 fixiert. EuroCrete ist ein Trivialbegriff für Polymerbeton (PRC = polyester resin concrete), dessen Praxistauglichkeit durch langjährige Erfahrung bewiesen ist. Die Quarzzuschläge sind chemisch nicht angreifbar; das Harz selbst ist für Säuren und Laugen über fast den gesamten pH-Wert Bereich (pH 1,0 bis 10) beständig. Die Kombination aus hochfesten Zuschlägen und Polyesterharz ergibt enorme Druck- und Biegezugfestigkeiten. Diese Eigenschaften machen Stahlbewehrungen überflüssig und führen zu schlanken, leichten Bauteilen. Die Schnellreaktion der Harze hat schnellste Abbindezeiten und sofort einsetzbare qualitativ hochwertigste Produkte zum Vorteil. EuroTop EuroTop – Innovative, muffenlose Kanalrohre aus Feinsteinzeug Innovativ und Zukunftsweisend EuroTop-Steinzeugrohre werden nach dem neuesten Stand der Produktionstechnik im Schnellbrandverfahren hergestellt. Die im Rollenofen bis zur Sinterungsgrenze gebrannten muffenlosen Rohre sind die moderne Alternative zu den in traditionellen Tunnelöfen gebrannten, glasierten Steinzeug-Muffenrohren. Das für EuroTop verwendete Feinsteinzeug verfügt über verbesserte Eigenschaften: hohe Scheiteldruckfestigkeit bei geringerem Gewicht exakte Maßhaltigkeit bei optimaler Baulänge glatte Oberfläche (ohne zusätzliche Glasur) immer Hochlast-Tragfähigkeit Die zugehörige Rohrverbindung ist die millionenfach bewährte Kupplung (Doppelmuffe) aus hochwertigem umweltfreundlichen Polypropylen (PP). Normgerechte Rohrverbindung Diese Kupplung aus Polypropylen ist auf den Außendurchmesser (d3) des EuroTop-Rohres optimal abgestimmt. Das d3-Maß der Rohre entspricht dem System E der DIN EN 295-1 und ist durchgängig für die Tragfähigkeitsklasse (TKL) 240 ausgelegt. Die PP-Kupplung mit integrierter Lippendichtung aus Elastomer ist gemäß DIN 4060 auf Dichtheit geprüft und vom Deutschen Institut für Bautechnik (DIBt) zugelassen. Die PP-Kupplung optimiert die Leistungsfähigkeit des EuroTop-Systems: zuverlässige Dichtheit leichte Montage schlanke Verbindung geringes Gewicht außerordentliche Robustheit wirtschaftlich und umweltfreundlich Das energiesparende Schnellbrandverfahren macht die Serienfertigung der muffenlosen EuroTop-Rohre besonders wirtschaftlich und umweltfreundlich. Dies resultiert aus der Kürze der Brennzeit, die gegenüber der herkömmlichen Brennmethode auf ein 20stel reduziert wird; bei der Produktion entstehende Emissionen werden minimiert. Einfach und Universell Die Zuverlässigkeit des durch Kupplungen flexibel gehaltenen Verbindungssystems basiert auf den geringen Maßtoleranzen der Rohre. Durch Übergangsdichtungen und -kupplungen (Adapter) kann das EuroTop-System an alle marktgängigen Kanalrohrsysteme angepasst werden. Für den Einbau und den Betrieb ergeben sich aus der günstigen Rohr-Muffen-Konstellation folgende Vorteile: Kopflöcher sind bei dem geringen Muffenauftrag nicht erforderlich, ein sattes Aufliegen der Rohre über die gesamte Länge ist damit besser gewährleistet. Die Maßhaltigkeit der Rohre bewirkt gleichmäßig verpresste Dichtungen und geringe Montagekräfte. Die lose Kupplung ermöglicht das Trennen der maßhaltigen Rohre für Kurzlängen über die gesamte Länge – bei minimalem Materialverlust Die erhöhte Flexibilität der doppelgelenkigen Rohrverbindung mit dem elastischen Kupplungskörper gewährleistet doppelte Sicherheit und Dichtheit auch bei extremen Bodenbewegungen. EuroTrad – Das traditionelle Steinzeugrohr mit Muffe Das konventionelle Programm von EuroCeramic für den Kanalbau heißt EuroTrad, das glasierte Steinzeugrohr mit Muffe. Seit vielen Jahrzehnten schützt dieses bewährte Produkt Grundwasser und Boden vor Verschmutzung: Sicher, problemlos und dauerhaft. Die ausgezeichneten Eigenschaften des Werkstoffes Steinzeug und die überzeugende Qualität der Rohre sind die Garantie dafür. Steinzeugrohre bringen für den Kanalbau Merkmale mit, die einen problemlosen Einbau und eine dauerhafte Betriebssicherheit gewährleisten. EuroTrad verkörpert dies durch: große Passgenauigkeit zuverlässige Dichtheit hohe Abriebfestigkeit hohe Druckfestigkeit Um die Vorzüge von EuroTrad für den Abwassertransport optimal nutzen zu können, steht eine umfangreiche Nennweitenpalette (DN 100 bis DN 600) und ein praxisgerechtes Zubehörprogramm zur Verfügung. Funktionelle Konstruktion Auf der Grundlage der DIN EN 295 sind die Verbindungssysteme durch Anwendung und Nennweite bestimmt. Bei kleinen Nennweiten bis DN 200, insbesondere im Hausanschlussbereich, wird für Rohre und Formstücke eine Lippendichtung verwendet. Sie wird werkseitig mit einem Edelstahl-Spannring fest in die Muffe verspannt und entspricht dem Verbindungssystem F. Für DN 200 kann zwischen Kompressions- (K-Dichtung) und Lippendichtung (L-Dichtung) gewählt werden. Ab DN 250 wird ausschließlich die K-Dichtung eingesetzt. Sie besteht aus zwei angegossenen Polyurethanen. Auf dem Spitzende ist der Verguss weich und in der Muffe hart ausgebildet. Diese Dichtung wird nach dem Verbindungssystem C der DIN EN 295 gefertigt. Die aufgegossenen Dichtringe gleichen Materialtoleranzen aus und führen unter Beachtung der Scheitelmarkierung zu einer durchlaufenden Fließsohle. Zur wirtschaftlichen Abdeckung verschiedener Einbauverhältnisse stehen in unterschiedlichen Nennweiten zwei Tragfähigkeitsklassen zur Auswahl. Eine Weiterentwicklung des traditionellen Steinzeugrohres ist das EuroTop-Rohrsystem der EuroCeramic. Durch einen neuartigen Herstellprozess und der Verwendung einer Polypropylen-Kupplung werden die EuroTrad-Eigenschaften noch übertroffen.

	DESULPHURATION PLANTS FOR DIGESTER GAS-BIOGAS Till now little attention was given to the removal of hydrogen sulphide. Higher environmental and safety demands require the removal of hydrogen sulphide out of the digester gas. The technically and economically best method is the classic removal of H2S by a cleaning compound based on iron oxide. This well-established process has essentially been improved. Meanwhile a small effort is needed to reach a high cleaning efficiency. Mode of operation The raw digester gas (or also another hydrogen sulphide containing gas) flows through a tower-type reactor. This reactor is filled with a cleaning compound based on a specific iron oxide in form of pellets. The hydrogen sulphide will be chemically bonded while passing the cleaning mass and so removed out of the gas. The cleaning compound will be naturally consumed by this process. Therefore a small amount of air is added to the raw gas in order to partially regenerate the cleaning mass and to minimise its consumption. The following chemical equations describe the process Cleaning 2 Fe(OH)3 + 3 H2S → Fe2S3 + 6 H2O ∆HR = - 63 kJ Regeneration Fe2S3 + 1,5 O2 + 3 H2O → 2 Fe(OH)3 + 3 S ∆HR = - 603 kJ By the addition of air the cleaning mass is restored to its prior condition. The cleaning efficiency will be reduced as soon as too much elementary sulphur has been accumulated on the surface of the cleaning compound pellets. This elementary sulphur can only be removed together with the cleaning mass. Only by this reason the catalytically running process cannot be perpetuated without consumption of the cleaning mass. Depending on the sulphur content in the raw gas, a high accumulation degree of sulphur can be achieved in the used cleaning mass, so that the absolute consumption of cleaning mass will be small. DIGESTERS FOR PRODUCTION OF DIGESTER GAS-BIOGAS DIGESTERS OUT OF REINFORCED STEEL Digester out of reinforced steel can be erected in high quality. The digesters can be economically produced in sizes up to 3000m3 by our own manufacturing. The complete equipment with mixing devices for sludge – as agitator or gas impressing – and the necessary installation of pipes from stainless steel can realised by us. The digesters are additionally protected with woven cased PE-HD-plates in the gas zone to reach a high protection in the high stressed areas. GAS FLARES FOR DIGESTER GAS/BIOGAS GAS FLARES FOR DIGESTER GAS/BIOGAS FUNCTION The gas flares have the task of burning digester gas if an utilisation by the combined heat and power unit or the heating is not available. The flares have to ensure that no unburned gas will be blown into the atmosphere. Thus hazards for humans and the environment are avoided. CONSTRUCTION The gas flare is composed of a flare burner and a flare substructure. It is designed according to the principle of an injection burner and consists of a nozzle, an injector with an air flow regulation, a flame protection tube, a fitting group and a flare control system. The gas flare is totally made out of stainless steel, whereas gas contacting parts are done in stainless steel AISI 316 Ti. The flare burner is made up of the flame protection tube, the injector and its supporting structure, the ignition and the flame monitoring. The flame protection tube and the injector are made out of stainless steel AISI 309. The flare substructure bears the flare burner and takes up the vertically installed fitting group. On demand it is able to provide it with a sheet-metal covering for protecting the fittings from the weather. Then a door enables a good accessibility. The fitting group consists of a magnetic or motor-driven valve (slow opening, fast closing, de-energised closed), a flame arrester and two pressure switches. The flare control system is fitted in a control cabinet out of stainless steel that is mounted on the flare substructure. The internal wiring to the fitting group, the ignition and the flame monitoring is completely done before delivery. MODE OF OPERATION Surplus gas is able to be burnt off by the flare once an adequate signal sets the flare into operation. Normally this signal is provided by the filling level indication of the gas holder. If the gas holder reaches its maximum filling level, the starting signal for the gas flare will be released. Then the flare control system initiates the ignition and opens the magnetic or motor-driven valve. The gas is now able to run through the valve and the flame arrester and is discharged with a high exit speed into the injector by the nozzle. Caused by the high speed of the gas the necessary combustion air is sucked into the injector from outside and a combustible gas/air mixture forms. Leaving the injector this mixture is ignited by an ignition electrode and burns off inside the flame protection tube. This tube provides a wind protection for a colourless burning flame. Once the gas has been ignited and a steady flame has been established the flare will burn until the filling level indication of the gas holder will send a shut-down signal. Then the magnetic or motor-driven valve will close and the burning process will be finished. An automatic restart of the gas flare will take place as soon as the starting condition, i.e. the maximum filling level of the gas holder, is fulfilled again. As an alternative to the filling level indication of the gas holder, the fluctuating gas pressure in the gas system can be used for switching the gas flare on and off. For this purpose there are two pressure switches available to adjust a maximum and minimum pressure as switch-on and shut-down value. The control cabinet contains the whole control system for the flame monitoring and the ignition of the flare. An ignition transformer feeds the ignition electrode that directly ignites the exhausting gas/air mixture at the injector. The combustion is monitored by an ionisation electrode that controls the ionisation current produced by the flame. If this ionisation current breaks down at a failure of the flame, it will be detected by the ionisation electrode and a re-ignition will be initiated by the automatic firing device. In case of a long running failure of the flame the gas supply will be interrupted and a malfunction message will be displayed. GAS HOLDER FOR DIGESTER GAS/BIOGAS Why do we store digester gas? The energy stored in the biogas cannot be used directly and transformed into heat and electric current at all times. For example the energy demand at night is usually lower as the one in the daytime. But, of course, the digester gas will be also generated at night and might be used to supply the higher energy demand during the day. But for that purpose storage of the gas is necessary. Also for the operation of the digester a gas holder might be necessary. The scum is often removed out of the digester by opening the scum door: Because of taking out a larger amount of liquid in this case, gas has to flow back from the gas holder into the digester to avoid damages caused by a vacuum. Limits of the digester gas storage Digester gas is an energy form with a very low energy density. For comparision: 1 m³ digester gas ≈ 0,6 l fuel oil Therefore the storage of gas produced excessively in the summer to supply the higher energy demand in the winter is not feasible for practical and economic reasons. Reasonably only the production of one day will be buffered. So the energy not used at night or during the weekend is able to be stored and utilized during the day. Especially for sewage plants which use the gas in a combined heat and power unit this is recommended. The produced electric energy can be used in the daytime in far better economic way. LOW PRESSURE GAS HOLDER FOR DIGESTER GAS-BIOGAS Function Low pressure gas holders were often inserted in municipal or industrial waste water treatment plants. This dryly working gas holder consists of a cylindrical steel tank that is built gas tight in its lower half. The ballast bearing plate consists of steel. It is conducted by a (telescope) guide tube. Ballast plate and steel tank are connected by a membrane. The smaller diameter of the membrane is attached to the ballast plate and the bigger one to the cylindrical steel wall at the middle altitude of the tank. When the gas holder will be filled, the inflowing gas raises the ballast plate. The membrane forms the ealing between ballast plate and wall. Mode of operation The operating pressure in the gas distribution system of a waste water treatment plant is given by the weight of the ballast plate of the low pressure gas holder. The sewage gas is generated without any pressure in the digester as long as it could freely exhaust. When the gas flows into a low pressure gas holder, it has to raise the ballast plate. At first the space in which the gas could flow in is consequently limited. The gas compresses until its pressure has compensated the counterforce of the ballast plate. From this point on the generated gas raises the ballast plate and the gas holder fills. During the discharging of gas out of the gas holder, the weight of the ballast plate keeps up the pressure of gas. The amount of ballast on the plate consequently determines the pressure of the discharged gas. Since the gas distribution system is a communing system, the gas pressure in the digestion and in front of the consumers is the same –discounting the inevitable pressure losses of the gas lines. Design Low pressure gas holders could be delivered in two versions: • welded steel tanks with corrosion inhibiting primer • enamelled steel tanks
