Pretreatment for Separation

Since the major part of the contaminants in municipal wastewater is associated with particles, direct separation of the particles is an effective way of lowering the water contaminant level. Sedimentation, filtration and flotation, with coagulation and flocculation have been used as the main separation processes for nearly 100 years. However many modifications and new technologies, such as membrane filtration have followed trends in the developing science of solid-liquid separation. The thirteen papers selected here provide a uniquely authoritative and concentrated update that will be of great value to all those researching or applying particle separation processes.
