Water treatment system-Reverse Osmosis

Basic flow:

Raw water tank--Raw water booster pump---Quartz sand filter--Active carbon filter—Scale inhibitor device---- Precision filter---- Reverse osmosis --- ozone generator---ozone mixing tower---pure water tank 

1.Water source tank

Since the raw water pressure is not very stable, it will cause unstable flow rate and affect the filtering effect. At the same time, in order to avoid impact on the preconditioner, the raw water tank needs to be configured to buffer and balance the water pressure. Equipped with two sets of liquid level control valves.

8.Ozone generator

This series of ozone generators use IGBT integrated technology to generate ozone by corona discharge, and the discharge chamber is composed of a tubular generator with a dehydroxyl quartz structure. Unique anti-return water design (return water is not easy to damage the machine), life is much longer than ordinary manufacturers, circuit adopts modular design, dielectric components, connectors and pipes are all anti-oxidation devices, not easy to oxidize, long working life, large corona area , The low temperature greatly increases the ozone concentration. Its performance indicators and actual use effect are better than most current similar products.

  Features:

1. The unique structure design makes the backwater not easy to damage the ozone generator.

2. The generator unit has a long working life and can work continuously.

3. The shell is stainless steel.

4. Dual-purpose type, air source and oxygen source can be selected and used according to needs.

Ozone is a strong oxidant, and its oxidation ability in water is second only to fluorine. Ozone can remove difficult-to-biodegradable organics in water, improve the bioability of organic wastewater, and reduce COD, chroma and ultraviolet absorption organics in the effluent.

Ozone may react with many functional groups, such as: double bond, triple bond, aromatics, heterocyclic compounds, cycloalkanes, =NN, =S, C≡N, CN, CS I, -OH, -SH, -NH2 -CHO and other companies equipped with ozone generation system can achieve sterility in water

10.Pure water tank

It is used to store reverse osmosis product water and is equipped with two sets of liquid level control valves. When one set reaches the high water level, the reverse osmosis device is notified to stop working to prevent water overflow. When the water level reaches the low level, the reverse osmosis device will automatically start to replenish water; One group will notify the delivery pump to stop working when it reaches the low water level to prevent the delivery pump from running dry due to lack of water. The delivery pump can be restarted only when the water reaches the high water level to avoid frequent actions.
