Plant
The daily output of the drinking water treatment system is about 1,000 litres. The equipment comprises a pump unit as well as an additional storage tank in which the water is conserved by use of SilverSan technology.
The water is filtered, sterilized and thanks silver ions added to the water conserved for the long term.
Then the purified water is being pumped into a closed tank, thus avoiding bacterial growth.
