Dissolved Air Flotation (DAF) Units
The Dissolved Air Flotation (DAF) process has been used extensively for wastewater treatment to remove suspended matter, such as fats, oils, and grease (FOG), total suspended solids (TSS), and insoluble BOD, from wastewater streams. bioprocessH2O provides a complete line of bioDAF units along with ancillary equipment for captial purchase, rental, and piloting. In the DAF process, air is dissolved in the wastewater, creating thousands of microbubbles which float and thicken the suspended material. The thickened and partially-dewatered solids are then segregated for recovery or disposal. Clarified effluent is available for discharge or further biological treatment and water reuse.
BioprocessH2O provides bioDAF units fabricated of 304 or 316 stainless steel and corrosion resistant components. Chemical flocculation/coagulation and chemical feed systems are provided to enhance solids removal based on the system design and operating requirements.
