Water is the most important element for life on earth.

Even human beings consist at about 80 % of water.

Today just about 6 % of earth population has access to pure water, and things get worse.

The protection of this essential ressource is our great challenge.

For that reason we want even more
than German environmental act demands:
BOD = 40 mg/l and COD = 150 mg/l

performs purification of sewage at the highest standard which allows reprocessing of water without any technical support.

 The quality of discharged water from is

COD < 40 mg/l    BOD < 5 mg/l     Total - P < 2 mg/l

Total - N < 30 mg/l      NH4 - N < 1 mg/l

 
reduces human pathogen bacteria at a range of almost 100 % to a water quality that meets all requirements of bath waterbody guidelines in the European Union.

Thus the recycled sewage can be used as process water in lavatories or for irrigation.
