The present invention is directed, among other things, to methods for reducing fouling of a separation membrane having a concentrate side subject to a concentrate pressure (Pc) and a permeate side subject to permeate pressure (Pp), comprising raising an initial permeate pressure (Pp.sub.0) to an increased permeate pressure (Pp.sub.1). The present invention further provides a method of reducing fouling of a membrane having a concentrate side subject to a concentrate pressure (Pc) and a permeate side subject to permeate pressure (Pp), comprising periodically raising an initial permeate pressure (Pp.sub.0) to an increased permeate pressure (Pp.sub.1). Additionally, the present invention provides an improved apparatus for filtering a fluid and methods of reducing membrane fouling in a separation membrane using the apparatus, the improved apparatus comprising a feed inlet having a pump, a filtering apparatus, a concentrate line and a permeate line, the improvement comprising:
