Apparatus for producing a rapid reduction in the pressure followed by a high velocity slug of liquid to dissociate collected solids from a filtration membrane surface utilizing an air accumulator, check valve and a timed rapid pressure blowdown to dislodge the collected solids and flush them from the membrane; or utilizing a high volume recirculating pump for recirculating liquid suffused with air and periodically stopping the pump for a predetermined time interval and draining liquid from adjacent the membrane, resulting in a reduction of the pressure, and then starting the recirculating pump to provide a high velocity flow of liquid to flush collected solids from the membrane.
