Dissolved air flotation system

It’s a highly-effective, proven technology for removing low-density particulates found in lakes and reservoirs, which are problematic for typical sedimentation systems. The Clari-DAF system excels at removing filter clogging algae and precipitated solids (TOC, Fe, Mn), as well as Giardia and Cryptosporidium.

Technical details

Removes primary contaminants such as algae, precipitated organics, iron, and manganese
No polymer required, excellent clarifier prior to membrane filtration
High loading rate – up to 16 gpm/ft2 (40 m/hr), 10 times that of conventional sedimentation systems
Compact design – up to 1/10th the footprint of conventional clarification
Water produced from system typically well below 1 ntu prior to filtration, yielding filter run times of 3-4 time that of previous sedimentation systems
Can be installed in concrete tanks or provided as steel package plants
Rapid start-up
Other applications include open intake seawater pretreatment, filter backwash recovery, and treatment of tertiary WW lagoon effluent
