M-160 water treatment system
The system may be used for water supply of the houses to 15 people at the consumption rate of 250 l/person in day.
When using water only for drinking and culinary, the system may be used for water supply up to 750 people.
The system is mounted on the frame of anodized aluminum machine-tool profile. The system pipelines are made of polypropylene pipes, the electrical communications are in the polyamide corrugated tube. The high-pressure pump is set on the isolation pads.
Technology of water purification
A source water comes to the input of the high-pressure pump and is delivered under pressure for treatment. A water is purified of mechanical impurities and dissolved organic matters in the preliminary filter according to the type of the used cartridges and comes to the nanofilter membrane case, where it is divided into the desalted permeate and the concentrate enriched by salts. The concentrate is dumped in sewage.
The purified water passes through the water counter of permeate, is dosed with sodium hypochlorite (depending on the version) and comes to the storage tank.

The system is fully ready for operation, has the consumable for operation for 3 months.
When operating, the system uses sodium hypochlorite, the filter cartridges and an electrical energy.
Sodium hypochlorite is used as 5% water solution (it is sold as BELIZNA trade mark). It is necessary to replace the filter cartridges after treatment of 10 m3 of source water. The system for water treatment consumes an electrical energy up to 4.5 kW·h per 1 m3 of purified water.
Drainage waters of the system are nontoxic, and their water evacuation on a relief and in the natural reservoirs is admissible without additional treatment.
The system is completely automated and does not demand a control from the user.
