Water Purification Equipment Backwash Water Filter
1. Features of water filter
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.

4. How water filter works
P-type automatic sewage filter is made of high-quality carbon steel cylinder, the special structure of the stainless steel wedge filter screen, flow direction valve and sewage drain. In the working status, flow direction valve is on, the water flow from the inlet into the filter, through the filter screen to the outlet (see Figure 1). When the filter needs sewage, flow direction valve closed, open the drain valve, water flows through the first half of the mesh filter, part of the water flow into the system from the outlet, the remaining water flow from the backside of the filter into the inside, automatic backwash the filter screen (see Figure 2). So that the entire washing process is operating normally, without downtime.
Flow direction valve opening mechanism include sub-manual and electric type, when using an electric opening mechanism with clock control electrical control box, it can set the time required to achieve automatic cleaning sewage, then the outfall installed electric ball valves, flow direction valve and sewage electric valve to achieve linkage.
