DAF Treatment Plant Industrial Effluent Treatment System

DAF Wastewater Treatment System. Dissolved air flotation DAF is a treatment process which removes suspended solids oil and grease from wastewater. Many appli ions use the DAF process but it is particularly useful for industrial wastewater treatment as it can reduce COD by up to 90%. Dissolved air flotation involves the creation of tiny air


The treated and clear water after the Flotation can be discharged to the sewer or further biological system for further treatment. We are specialized in modular dissolved air flotation systems and offer reliable semi-mobile plants for industrial wastewater treatment.

WasteWater System: Dissolved Air Flotation DAF System

Recovery of Calcium Carbonate from Wastewater Treatment

disposal of the solids removed or generated during treatment 1 . The flotation process is widely used in industrial wastewater treatment plants where it is used to remove fats oil grease and suspended solids from wastewater. These units are called Dissolved Air Flotation DAF units.

Dissolved Air Flotation DAF System - CFC-Flotation

It can be assumed that about 40 to 60 liters of flotation sludge per m³ of wastewater are produced at average concentrations. This is approximately 4 to 6 % of the volume of the waste water entering the DAF system. The flotation sludge further dehydrates during storage thus the longer it is stored the less water content the sludge has.
