Water Treatment and Supply System MO-140

The system of water treatment, water storage and water supply MO-140 is designed to purify water from open ponds, wells and boreholes from suspended solids, colloids, disinfection from bacteria and viruses, removal of iron compounds, manganese, copper, sulfur, phosphorus, organic substances (including petroleum products), dissolved salts, including compounds of one-, two- and polyvalent metals, storage of treated water and delivery of treated water under pressure to the consumer's water supply network (pumping station after the system is not required). The system can be used to supply water to individual houses with simultaneous residence of up to 12 people at a consumption rate of 250 litres/person per day.
If water is consumed only for drinking and cooking, the system can be used to supply water to up to 600 people.
The system consists of two units - a water treatment unit and a storage tank for purified water.
The equipment of the water treatment unit is mounted on a frame made of anodised aluminium machine profile equipped with vibration-isolating wheels. Pipelines of the water treatment unit are made of polypropylene pipes, electrical connections are made of polyamide corrugated pipe. All units with asynchronous electric motors are mounted on vibration supports.
The storage tank for purified water is made of food-grade polyethylene, equipped with a lid with a breathing valve, equipped with level relay electrodes and fittings for connection to the water treatment unit.
Water treatment technology. The initial water comes to the inlet of the high-pressure pump, and under pressure is supplied for treatment. Water is cleaned from mechanical impurities and dissolved organic substances (optionally, depending on the type of cartridges used) in the pre-filter, mixed with compressed air and delivered to the pressure aeration tank.
The pressurised air dissolves in the water. The dissolved oxygen interacts with the dissolved impurities on the surface of the catalytic backfill. Iron, manganese, ammonia and hydrogen sulphide are oxidised in the pressure aeration tank. The suspended solids formed during oxidation are retained by the catalytic backfill layer.
Periodically (at each filling up to the upper level of the treated water storage tank), the catalytic backfill is automatically washed with the reverse flow of treated water.
The treated water from the pressure aeration tank enters the post-filter, where suspended solids not captured in the catalytic backfill layer, wear products of the backfill, and dissolved organic matter adsorbed (optional, depending on the type of cartridges used) are removed.
The treated water then enters the nanofiltration membrane housing, where it is separated by the membrane into a desalinated permeate and a salt-enriched concentrate. The concentrate is discharged from the treated water block into the sewer. The concentrate is also discharged into the concentrate discharge line with the wash water from the pressure aeration tank.
The treated water passes through the permeate counter, is supplied with a preserving dose of sodium hypochlorite and enters the storage tank.
The treated water is pumped out of the storage tank by a purified water pump and fed into the consumer's water supply network and for flushing the catalytic backfill. For correct operation of the pump control system, a membrane tank is included in the purified water supply line.
