Abstract

An apparatus and a method are provided for separating a feed fluid into a filtrate and a concentrate. A filtrate chamber is divided into several separate filtrate subchambers, each of which is connected to a different portion of a partially permeable wall or membrane to receive that part of the filtrate passing therethrough. A relative motion is induced between the feed fluid and the wall or membrane by a rotating part, thus preventing clogging of the membrane. Sensors are provided in the filtrate subchambers, permitting information about a dynamic separation process to be obtained.
