GWRS 20 grey water plant

GWRS 20 grey water plant

GWRS plants provide process water of the highest quality, fulfilling the sanitary/microbiological requirements of European standard EN 16941-2 (systems for use of purified grey water) without using harmful chemicals, while being inexpensive in terms of operating costs (purification of 1m3 of water consumes only 0.5 kWh of electricity).

It operates on the principle of rapid purification in order to satisfy demand quickly and reduce the need for using large water storage tanks. It is an ideal solution for large facilities and installations where space is limited.
