    Abstract: The invention is a development of the apparatus of Specification 982425, the new features being (a) two concentric sets of filter tubes, those in one set being staggered in relation to those in the other set; (b) a central tubular member extending through the outlet chamber and providing communication from the inlet end of the housing to the other end; (c) the provision of bearings for the back-wash tube at both ends of the housing, the backwash tube extending through the above-mentioned tubular member; (d) the provision of two hollow radial arms of unequal length extending from the back-wash tube at each end of the outlet chamber, the longer arm communicating with the outer set of filter tubes and the shorter with the inner set, at each end. Thus each filter tube is open at both ends, and during back-washing filtrate and residue are discharged from both ends simultaneously.
