Clarification of high strength wastewater using dissolved air flotation technology [Full subscriber]

Dissolved air flotation (DAF) systems are designed to remove suspended solids from water slurries. Clarification is achieved by the addition of pressurized air as fine bubbles. The microscopic bubbles attach to the solids reducing its specific gravity, allowing the material to float. SMBSC has tested several DAF units to clarify high strength water flows. The test results showed good removal of fine soil particles producing an effluent suitable for the wastewater treatment plant.…
