Auto Backwash Filter
Auto back wash Self Cleaning Filter is used for Preliminary Filtration of demanding application of Various Industries.Its very useful for applications where suspended solid load is Comparatively high & highly viscous material and slurry based filtration applications.
Operation
Auto Back wash type self cleaning filters work on a flow direction of outside to inside. Unfiltered fluid enters into filter housing through bottom tangential inlet connection. Contaminants are deposited on the outer surface of filter elements and clean filtrate passes through inside diameter of element and removed through the top tangential outlet. Users can set their differential pressure data within control panel. Once the differential pressure across the system reaches the pre-defined level of pressure drop, inlet and outlet valves shut down and the drain and backwash valves open for defined interval of time. During this process, debris deposited on outer surface of element shall be drained out and collected through bottom drain. This cycle continues as per pre-defined settings and process requirements.Auto Back wash type systems are available with multiple filter elements, wherein one element is in use and the other can be cleaned at the same time. This will help to have uninterrupted flow of the fluid.
