Lesson 14: Sedimentation and Flotation

2008-2-6  Dissolved Air Flotation (DAF) is very widely used in treating the industrial wastewater effluents from oil refineries, petrochemical and chemical plants, natural gas processing plants, paper mills, and similar industrial facilities. A very similar process known as induced gas flotation is also used for wastewater treatment.

Sedimentation Processes IWA Publishing

2021-11-20  Sedimentation is one of several methods for application prior to filtration: other options include dissolved air flotation and some methods of filtration. Generically, such solids-liquid separation processes are sometimes referred to as clarification processes. There is a variety of methods for applying sedimentation and include: horizontal flow, radial flow, inclined plate,
