Water Treatment and Supply System O-200 for Effective Water Purification

The system of water treatment, water storage and water supply O-200 is designed to purify water from wells from suspended solids, colloids, dissolved organic substances, iron, manganese, sulphur compounds, storage of purified water and delivery of purified water under pressure into the water supply network of the consumer (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 20 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 1000 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 tank for storage of treated 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 purification 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 tank for storage of purified water) automatic water-air washing of the catalytic backfill by reverse flow of purified water and compressed air is carried out. The treated water from the pressure aeration tank flows into 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 passes through a water meter, is supplied with a preservative dose of sodium hypochlorite and enters the storage tank.

From the storage tank, the treated water is pumped out 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.
