1. Advantages of Backwash Water Filter

1. Automatic backwash
2. Strong magnetism for descaling
3. Automatic drain

2. Features:

1. Small volume, low cost, no filter, a small amount of maintenance.
Long mesh tube network life and high reliability.
2. High degree of automation, easy operation and management, long-term unattended operation.
3. Low pressure loss, energy saving, the use of the main channel hydraulic backwash, no need for backwash water.
4. Filtration precision: 1000-5000μ M.
5. Easy to install, can be installed directly on the pipe, particularly suitable for field use under various process conditions.
6. Widely usage, ensure a safe operation of the water utility, simple and reliable method in any backwash process, can maintain uninterrupted normal operation.

3. Applications

1. The domestic water supply, water supply and pre-filtering for industrial water supply;
2. Steel, petroleum, chemical, paper, automotive, food, metallurgy and other industries beginning circulating water filtration;
3. Fist stage of circulating cooling water filtration;
4. The water reuse, waste Water Treatment filter;
5. Central air conditioning, boiler return early filter;
6. Municipal, green spraying, irrigation, agricultural irrigation, drip Irrigation water filter early.

4. How water filter works

The internal structure of automatic backwash type filter is made of intellect steel (or stainless steel), special structure stainless steel strainer, automatic butterfly valve, pressure differential switch, automatic drain valve and control unit. When the water enters into the filter equipment impurities is removed from water through stainless steel strainer. Automatic butterfly valve will close when the pressure differential value reaches to pre-setting value. When the butterfly valve closes, water in the internal of strainer will go out through outlet. The water between the chamber and external of strainer will backwash the strainer, the impurities will be washed by water and took away through drain valve.
