Quick backwash dirt separator adopts the most reasonable structure in accordance with principles of fluid-dynamics, and achieves low resistance. Quick backwash dirt separator is installed in pipe systems, not requiring any by-pass pipes. The equipment may carry out back-flushing blow-down at any time without shutting down, which guarantees normal operation of the system. Therefore, it is superior to other similar products and is very popular in the market. 
Quick backwash dirt separator can be classified into straight-through type and angle-through type according to service condition.

Working Principle of Quick Backwash Dirt Separator
When the dirt separator works, the butterfly valve plate is fully open; media enter into the inner side of the filter screen through inlet flange a, then flow into the outer side of the screen after mesh filtration, and finally leave the dirt separator through outlet flange b and enter into the pipe system.

During the discharge of impurities, the butterfly valve plate is closed; open the outer valve of drain pipe; due to the pressure difference between the inside of dirt separator and the outside of drain pipe, the media will change flow direction, running from the outer side of the filter screen to the inner side. Thus, impurities and dirt will be flushed out of the separator. During the discharge of impurities, most media enter into the pipe system through outlet flange b; the system does not to stop.
