Dissolved Air Flotation Problems

Dissolved air flotation (DAF) is a water treatment process for removing oils solids and greases from a water supply The process helps clarify wastewaters by eliminating different types of suspended matter DAF dissolves air in pressurized water – then releases it at atmospheric pressure

Dissolved Air Flotation

Dissolved air flotation systems advantages and application Dissolved air flotation systems The dissolved air rapidly carries solids and fats to the surface without problems with unpleasant odours and with an extremely high efficiency of removal This permits a reduction in pollutant load and hence in the dimensions of the whole installation.The ALAR Dissolved Air Flotation [DAF] is a water clarification system that is excellent for high volumes of wastewater containing low percent solids The ALAR DAF uses dissolved or inspirited air to concentrate and float fine solids fats oil and grease The streamlined design uses minimal space while providing ample residence time.
