Abstract:
A method for removing particulates from a stainer positioned in a contaminated water flow having particulates therein, said method comprising the steps of:disposing a first outer surface of a stationary cylindrical porous member in the contaminated water flow to capture particulates against said first outer surface; positioning a portion of a housing containing an ultrasonic energy source within an inner region of said stationary cylindrical porous member defined by a downstream second inner surface of said stationary cylindrical porous member, said second inner surface permitting passage of a cleaned water flow; isolating said stationary cylindrical porous member from said contaminated water flow, activating said ultrasonic energy source to dislodge particulates from said first outer surface; and sending a reverse flow of clean water through said second inner and first outer surfaces to evacuate said dislodged particulates from returning to said first outer surface.
