Some aspects of application of waste polymer materials as a coalescence medium for oily wastewater treatment

Abstract Wastewaters from many industrial processes may contain significant quantities of free and dispersed oils. Classical separation techniques do not have a high efficiency if the droplets are very small (<20μm). In order to achieve efficient separation, various types of coalescer separators are in use. This paper deals with the use of waste polymer materials as coalescing media. The design of a new type of coalescer‐separator (removing free and dispersed oil simultaneously) is also given.
