Strategies required to control pollution of the membrane in pervaporation (PV) process was investigated. Simple spiral-wound modules was used for the tests. During the long term operation the membrane got polluted, and were found to be most foulants on the membrane consisted of iron and aluminium . Oxalic acid was very effective to remove them. Pressure loss of the module could be controled by membrane cleaning using oxalic acid, reverse flow of feed or gas injection into feed. Foulants deposited on the membrane did not affect the removal rate of trihalomethanes from drinking water.
