Application of Dissolved Air Flotation in Biological Waste Treatment Plants (Primary Clarification, Secondary Clarification and Sludge Thickening), and Water Purification Plants

摘要

Applications of dissolved air flotation (DAF) in a biological waste treatment plant as a primary clarifier (primary flotation), a secondary clarifier (secondary flotation), and a sludge thickener (flotation thickener) are studied and experimentally evaluated. Application of DAF in water purification plant is also studied. After completion of laboratory experiments, parallel comparison between conventional system and innovative DAF system is made from both technological and economical view points. Design criteria of innovative DAF systems are generated from laboratory and pilot plant testings.
