Abstract
Microporous polypropylene hollow-fiber membranes offer significant adv antages over packed-tower aeration for removing volatile organic chemi cals. A laboratory study assessed the performance of membrane air-stri pping in continuous operation, while exposed to various pretreatments. Results indicate that membrane air-stripping is compatible with low-p H or low-chlorine waters but not with waters of high pH or high-chlori ne concentration or those that are ozonated.
