Separation of Volatile Organic Compounds from Water by Pervaporation

摘要

Pervaporation for the removal of VOCs from water streams is a new technology. The first commercial plant was only in- Stalled in 1996. The process can remove Dissolved VOCs from industrial waste- Water, groundwater, and aqueous pro- Cess streams. The systems provide an Economical treatment method for streams Too concentrated for carbon adsorption Or air stripping and too dilute for incin- Eration or distillation. Because the pro- Valuable thermally labile organics, such As flavor and aroma components of food Processing streams, can be recovered.
