Unique Features:

We have learned from the deficiencies of other drinking water treatment technologies and have refined these technologies.

The following features prove this and hence clearly speak for C-MEM Zero:


Transportable system


hence can be used in all places where clean drinking water is needed urgently and quickly.


Operation without electricity

 C-MEM Zero System Stainless Steel

hence independent of power supply.


Operation without chemicals

Wasserglas_Water Glass

hence more environmentally friendly and healthier for man.


Further product development C-MEM Zero

SFC Umwelttechnik GmbH has further developed its currentless drinking water treatment unit C-MEM Zero: It is now also available with a downstreams active carbon unit as well as with a solar driven inlet pump.

By adsorption C-MEM Zero Active Carbon removes contaminations from water which cannot be removed by filtration e.g. pesticides, fertilizers, pharmaceuticals, heavy metals etc.

C-MEM Zero Solar replaces the manual filling of the raw water tank by a solar driven pump and is therefore an additional user-friendly option of C-MEM Zero.
