The next step in surface aeration
Oxybooster in combination with Landy-7 The next step in surface aeration
|
In order to improve the efficiency of a surface aerator an oxybooster can be installed in the aeration basin. This oxybooster consists of a number of baffles which are positioned in the lower part of the basin, but higher than usual, resulting in a higher oxygen transfer.
This Oxybooster has already proved its existence in praxis.
Landustries R&D department is continuously searching for ways to optimise her products, of which the Oxybooster is the latest result.

Energy savings upto 30%
Slow speed surface aerators can often be much more effective and can save a substantial amount of energy when the operation of the aerator is based on the real load and not on the original design parameters of a sewage treatment plant
Energy savings upto 30%Slow speed surface aerators can often be much more effective and can save a substantial amount of energy when the operation of the aerator is based on the real load and not on the original design parameters of a sewage treatment plant
This conclusion if very important because 80% of the power at a waste water treatment plant is consumped by aeration.
Surface aerators can be much more effective and efficient. At the design stage of a waste water treatment plant the calculations are based on the maximum load of the plant, including a projection of growth for the lifetime of the plant (the number of aerators and sizing is based on those parameters).
But what happens when the load is much less than anticipated and the circumstances are quite different then originally assumed?
By adapting the installation to the actual loading one can improve the efficiency and the process considerably and thus save a substantial amount of energy.
Landustrie has developed a toolbox for checking the functioning of the surface aerators in relation to the actual load. the goal of this aeration scan is to optimise the aeration, thus improving the efficiency and durability. The savings can be as much as 30%.
Lower energy costs for screw pumps Lower energy costs for screw pumps
New drive techniques and screw pump sizing reduce energy consumption
Until today most archimedean screw pumps are executed with V-belt transmission. This traditional application however is outdated. If a direct drive is applied the energy consuming V-belt transmission is no longer necessary. This results in a saving of approx. 5%

If a direct drive is applied the energy consuming V-belt transmission is no longer necessary. This results in a saving of approx. 5%.
The direct coupled drive-unit, in combination with a frequency convertor, can be much easier fine-tuned to the actual supply of the treatment plant. In other words, no more energy than strictly necessary will be used. On top of that other advantages will be accomplished by fine-tuning the screw pump capacity to the supply of the plant, such as a much better process control.
Furthermore Landustrie uses a new erection method for screw pumps, also leading to energy savings. Nowadays a casting mould is used for realisation of the concrete screw trough. With this new method a higher wear resistance is achieved and a clearance between screw and trough is fixed for lifetime. Increasing leak losses will be a matter of the past. This new casting method results in a high efficient screw pump.
Landustrie's basis was laid around 1913. The company was active in the agricultural market sector and involved with polder drainage at an early stage.
As early as 1916 electrically driven pumping stations were installed with Archimedean screw pumps, together with the countless pumping stations with so-called wind motors.
After some time, in addition to the polder drainage pumps, pumps for handling sewage were developed. By the 1950's this advance opened the way to waste water purification units being used widely and efficiently.
With almost 90 years of world-wide experience Landustrie has become a leading company in the field of sewage and waste water treatment.
The present organization mainly consists of two product groups:
Pumps & Pumping Stations
and
Sewage Works
These groups are completely responsible for the acquisition, sales, engineering and project management within their own market section, all over the world. 
| Archimedean screw pumps For nearly 100 years Landustrie has designed, manufactured, supplied, erected and maintained many types of screw pump configurations. With a fully automated screw pump selection program the optimum screw pump can be choosen for any particular application.
Applications:
waste water treatment plant influent pumping stations
waste water treatment plant intermediate pumping stations
return sludge pumping stations
irrigation projects
drainage projects
reclamation of wetlands
circulation within aeration systems
wild water tracks in fun parks
industrial applications
storm water applications | 
| Condition monitoring All our screw pumps can be equipped with a condition monitoring system.
This system on-line continuously supplies details about the upper and lower bearing.
The monitoring is based on acoustic emission sensors which detect possible problems at a very early stage.
Not only operating and maintenance costs will be reduced, but also the expoitation and usability of the screw pump installation will be increased.

| Landox flow boosters In order to meet high requirements for flexibility, capability, operational reliability, operating costs and the environmental demands of minimal noise and aerosol generation, Landustrie developed the Landox channel aeration system.
This system is based on the well known principle of an oxidation ditch in which both fine bubble aeration and propulsion of the mixed liquor can be independently controlled.
Propulsion is effected by one or more low speed vertical Landox drums, positioned in de bends of the aeration circuit.
The rotors are suspended on specially designed Landox upper bearings. Therefore the application of submerged lower bearings is no longer necessary.
Aeration takes place by means of diffusers (ceramic, plastic or membrane) mounted on the bottom of the aeration circuit.
high oxygen transfer (3 to 4 kg O2/kWh)
low propulsion energy (1.25 to 2.50 W/m3)
high overall efficiency
lower diffuser density
low maintenance and construction costs because of simple channel layout
optimal process control by adjustment of aeration capacity, independing on propulsion
denitrification is simply realised
applicable in existing circuits with surface aerators |
