A crossflow filtration system for constant permeate flux membrane fouling characterization
Review of Scientific Instruments, 2013Membrane fouling is often characterized using a crossflow filtration apparatus. Typically, the transmembrane pressure (TMP) difference is fixed, and the flux is allowed to decline as the membrane fouls and the resistance to mass transfer increases. However, as flux varies, so too does the rate at which foulants are brought to the membrane surface, so ...

Permeate recovery and flux maximization in semibatch reverse osmosis
IDA Journal of Desalination and Water Reuse, 2013AbstractMost reverse osmosis (RO) and nanofiltration (NF) processes operate as once through or plug flow (PF) systems in which permeate recovery, flux and cross-flow are coupled. Such processes are well suited for applications where permeate recovery percentages are limited and where well pretreated source waters of uniform composition are available ...

Gas separation by permeators with high‐flux asymmetric membranes
AIChE Journal, 1983AbstractThe permeation behavior of the high‐flux asymmetric membrane differs from that of the conventional symmetric membrane. A calculation method for predicting the gas separation performance of a permeator with asymmetric membrane is presented. The model takes into account the permeate pressure drop and is applicable to both hollow‐fiber and spiral ...
