Abstract
A separator cell for pressure filtration and reverse osmosis includes a housing; a filtering membrane supported in the housing and having a feed side and an opposite filtrate side; a flow guide plate supported in the housing and being in a face-to-face engagement with the membrane on the feed side thereof; and a channel in the flow guide plate for guiding fluid. The channel is covered by the membrane. A feed pipe supported in the housing has an outlet and a concentrate discharge pipe supported in the housing has an inlet, both communicating with the channel. A filtrate discharge pipe is supported in the housing and has an inlet at the filtrate side of the membrane. The outlet of the feed pipe and the inlet of the concentrate discharge pipe are situated at generally diametrically opposite locations of the flow guide plate. The channel is constituted by a channel having a shape of a continuous spiral formed of a first and a second turn. The first turn starts at the outlet of the feed pipe and has a curvilinear course of continuously decreasing radius. The second turn is a continuation of the first turn and has a curvilinear course of continuously increasing radius. The second turn terminates at the inlet of the concentrate discharge pipe.
