Abstract
Rotary filtration devices have at least one inner member (36) and at least one outer member (26), which rotate and define a fluid filtration gap (48) therebetween. During filtration, permeate passes from the feed fluid in the gap (48) through the filters (34) facing the gap (48). The inner member (36) has an internal pathway (46) for the flow of feed fluid.
Fluid to be filtered flows from the body of the feed fluid through the internal pathway (46), reverses direction (70), and flows through the filtration gap (48) back to the body of the feed fluid. Alternatively, fluid to be filtered passes from the body of the feed fluid through the fluid filtration gap (48), reverses direction, and flows through the internal pathway (46) back to the body of the feed fluid. The outer member (26) may be closed so that feed keeps circulating in the fluid filtration gap (48) until it leaves through the filter (34) as permeate or reenters the surrounding reservoir (60) of feed fluid.
