MF-140-2 water treatment system
The MF-140-2 water treatment system is designed for water purification of open reservoirs and wells from suspensions, colloids, disinfection from bacteria and viruses, removal of the compounds of iron, manganese, copper, sulfur, phosphorus, organic matters, and dissolved salts, including hardness salts.
The system may be used for water supply of the houses to 14 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 600 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 is sucked by the high-pressure pump and delivered to the preliminary filter case, where it is cleared of mechanical impurities and dissolved organic matters in the preliminary filter according to the type of the used cartridges, a fine purification from suspensions and a sorption of organic matters are carried out in the intermediate filter. Then a water comes to the UV sterilizer, where the microorganisms passed through the filter are removed. The sterilized water is dosed with antiscalant by the pump-batcher to eliminate a deposition of salts on the back osmosis membrane. A water comes to the back osmosis membrane case, where it is divided into the desalted permeate and the concentrate enriched with salts. The concentrate is dumped in sewage.
The purified water comes to the storage tank (there is not the tank in the set of delivery).
A purified water pressure required for back osmosis is provided by two ball cocks of the pressure adjustment unit. The sediment formed on the membrane is dumped in sewage during direct flushing at regular intervals when switching on the electromagnetic valve.
The pump-batcher for delivery of sodium hypochlorite sucks a sodium hypochlorite solution from the tank and deliveries it in the purified water at regular intervals by a signal of the water counter.
The presence of a water source pressure at the system input is controlled by the pressure relay, the differential pressure of the filters is controlled by the pressure difference relay.

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, antiscalant, 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.
