Transverse flow: Liquid flows into the liquid inlet, crosses the hollow fibers, and then exits through the opposite port. No baffle is used. A vacuum or strip gas can be applied to either gas port · Radial flow: A plugged center tube on one side forces liquid radially over the hollow fibers. Primarily used for degassing low surface tension fluids · Extra-flow in high pressure vessel: An RO-style vessel generates a much higher maximum pressure. Liquid is directed radially across the membrane array by a baffle
