摘要: Removal of organic compounds from a water stream (3) involves gas stripping in gas stripper (1), followed by membrane separation of the stripping gas containing the organic compound (5) in membrane separator (2). Stripping can be carried out using one or multiple gas strippers and using air or any other gas as stripping gas (8). The membrane separator (2) can be a single-stage membrane unit or a multistage unit. The removal of organic compounds is particularly suited for treatment of contaminated groundwater or industrial wastewater.
