Abstract

Methods and systems for fluid filtration via semipermeable membranes is provided with means for their fouling prevention. An improved conventional filtration system includes a pressure pump (24), a membrane module (28), an inlet port (30), a concentrate outlet (36) and a filtrate outlet (34). The membrane is cleaned by applying an additional reciprocal fluid pulse to the fluid passing through the module which is achieved via a corresponding supplementary means: pressure pumps (42, 44, 46), diaphragm cylinders (78, 80, 82), piston-type thrust cylinders, hydraulic cushions (90, 92, 94) or hydraulic cylinders (66, 68, 70). Each of them having an individual actuator (48, 50, 52) associated with a control system (54).
