摘要： A filtration system is disclosed which operates with a single supply pump to achieve backwashing in an expeditious manner. The system includes a fluid supply source for a feed fluid to be filtered, a feed pump in fluid communication with the source and a membrane filter module for separating the fluid into filtrate and retentate streams. A collection reservoir is also provided which has at least two isolated fluid compartments movably separated from one another, one compartment for accumulating filtrate, the other being in fluid communication with the supply pump. In a preferred embodiment the collection reservoir is in the form of a diaphragm unit. At appropriate times, valves are activated to divert the flow of feed material from the supply source to the other chamber of the diaphragm unit. At the same time, flow in the effluent conduit is restricted by suitable means such as a valve, restrictor, pumps or the like, thereby forcing the fluid in the filtrate chamber back through the filtrate conduit to the "underside" of the membrane filter. The resultant pressure creates a back pulse which backwashes the filtration surface of the membrane to remove particular matter thereon.
