Abstract
Described is a self-cleaning filter for a liquid stream confined in a pipe,. The filter includes a porous ceramic filter body,having a power source,attached thereto. Upstream from the filter body a helical rib,and a sump drain tube,are provided. In operation, as the filter becomes clogged, an electrical current is applied causing the ceramic body to exhibit ultrasonic transducer properties which dislodge particulates from its upstream face,. At the same time, a sump valve,is opened to remove the particulate-rich liquid. The helical rib imparts a rotary motion which creates a rotary flow component across the upstream face of the filter.
