HYLANDER DISSOLVED AIR FLOTATION
Dissolved Air Flotation (DAF) is used as a method to separate contaminants from various waste streams. In the past, DAF systems were used only for high flow applications. Recent technology now makes it possible to economically treat low flow applications using a new pump design and the patented Redux™ Clarifier.
DAF The Hylander/Redux™ DAF uses a new pump design developed for Dissolved Air Flotation. Air is drawn into the pump at the suction side and forced into solution under pressure. When the pressure is released, the air becomes an effervescent stream of very tiny bubbles (30 micron in size) that attach to the coagulated particles. This new DAF design eliminates the need for large air compressors, holding tanks for residence time and extra pumps and piping.
Hylander/Redux™ DAF Systems can process flow rates as low as 3 GPM or as high as 100 GPM.
HOW THE HYLANDER/REDUX™ WORKS
|»||Dirty water is fed through a process tank.|
|»||Chemical pumps add coagulant, pH control chemicals and a flocculent into the waste stream.|
|»||Pressurized air is dissolved into the solution by the special DAF pump.|
|»||When the water enters the Redux™ Clarifier, the pressure is released into atmospheric pressure and tiny bubbles form.|
|»||Solids and coagulated materials are carried to the surface by the bubbles, while clean water flows from the bottom of the Clarifier and redirected back into the process tank.|
|»||Contaminants accumulate in the top of the Clarifier, eventually being forced out the top and into a solids collection tank for future treatment.|
