	Charge Treatment The classic charge treatment conforming to the latest state of technology is utilised for treating conventional industrial waste water in a plant. With this process technology, waste water is neutralised, heavy metals precipitated, complexes broken down and in the in-series full purification stage, the solid matter content is filtered out, dehydrated and separated.
	Filter Press The solid matter content contained in the waste water is filtered out in the filter press and dehydrated with the aid of pressure (10 - 15 bar). A compact filter cake emerges with an average dry weight of about 30 % that can be disposed of at a waste dump. Depending on the production process, the filter cake may contain valuable substances. In such cases, the reclamation of these substances is often worthwhile, through which the costs of disposal could be accordingly reduced. In addition, with this procedure the provisions of the Recycling Economy Law are fulfilled.
	Final Purification To prevent limit values from being exceeded due to bivalent metals in the waste water, the waste-water treatment plant can be supplemented with a final purification stage connected in-series (selective exchanger). The charged resins are regenerated, the exchanger is then up to its full admission capacity again. Very interesting in this field of application are exchangers with special resins used for the reclamation of precious metals as well as scavengers for bonding organic materials present in the waste water
	Ion-Exchanger Plant Under the heading "Water-Saving Measures" falls, amongst other things, the circulation management of rinsing waters via an ion-exchanger circulation plant. There, the ions dissolved in the rinsing water combine with ion exchange resins. The out-flowing, fully demineralised water is fed back again into the rinsing facility. The savings in water lie close to about 96 %.
	Micro-filtration This modern membrane-separating process is used to extend the service life of degreasing baths, finishing solutions etc. Those substances in the working circulation that interfere with the process are thereby concentrated, whilst the filtrate containing additives can be fed back into the work process again.
	Ultra-filtration Ultra-filtration works as a membrane-separating process according to the same principle as micro-filtration. It differs from this in the smaller pore size. Consequently, ultra-filtration is used both for the circulation management of active substance baths or treatment solutions as well as for the final treatment of ineffective bath solutions, emulsions, grinding and polishing fluids. The quantity of waste accruing, that is to be disposed of, can be reduced to about 10 % of the original volume
