A filtration unit contains a plurality of filter housings, each filter housing having a cylindrical shell with a lower port, an upper port, and a filter element. The lower and upper ports direct fluid through the filter housing in a first direction during a filtering cycle and direct fluid through the filter housing in a second direction during a backwashing cycle. The unit also includes a diverter and a servomechanism that rotates the diverter to selectively connect the filter housing to a drain port for the backwashing cycle.

Servo-controlled backwash filter system

The system of the present disclosure enables a filter cartridge having an array of filter media tubes to be remotely selectively back flushed during service by sequentially flushing the tubes with the rotary valving element to permit removal of trapped filtered material in service without disrupting the filtering flow in the balance of the filter array.
