ABSTRACT:
A bioreactor arrangement comprises a housing defining a closed space having a longitudinal axis with at least two spaced apart microporous membranes fixed therein dividing the space into a first chamber on one side of one of the membrane, a second chamber on one side of the other membrane, and a third chamber between opposite sides of the one and other membrane. The housing includes at least one port communicating with each chamber and fixed static mixers in the form of curved and/or perforated members in the third chamber. The first and second chambers are used alternately to receive and discharge material in the bioreactor. The third chamber contains an active substance which produces a useful product from raw materials in the supplied fluid. A flow valve and pump are provided for selectively supplying fluid carrying raw material to one or the other of the first and second chambers. The flow through the housing is reversed after a selected period of time or after a selected pressure level has been reached in the housing to avoid fouling of membrane surfaces and prevent the formation of any appreciable caked substance on any membrane surface. Additional ports are provided to the first and second chambers and connected over valves for discharging products.
