Abstract
In many U.S. municipal sewerage systems, oils, greases and fats are now being regarded as hazardous wastes. In this study, the authors discuss the need for complete oil removal and progression towards recycle of wastestreams. The use of ultrafiltration is recommended to clean emulsified oil streams, and also the use of absorption media to polish the ultrafiltration product water to a point where recycle is both feasible and within a reasonable economic realm.
