Dissolved air flotation Description
The DAF combines Ph Control, Coagulation, Flocculation and Flotation, all in one unit. The Patented SYSDAF technology does not require compressed air or bottom scraping. Dissolved air is provided to the system all along the bottom of the flotation tank and this ensures very efficient operation, maximum removal of pollutants and no sedimentation.
DAF is designed to mainly remove fats, oils and grease (FOG), suspended solids (TSS), parts of biological oxygen demand (BOD) and chemical oxygen dem and (COD) that hard to be dissolved in water and other pollutants from waste water. The process is simple - tiny bubbles attach to solid contaminants causing them to float and then sludge is skimmed off the surface of the water - but designing a DAF system for a real-world application isn't quite as simple.
Dissolved air flotation Feature
Small footprint, Low energy consumption; Easy operation; Simple management;
Efficient dissolved air; Stable treatment effect ; Full-automatic operation;
Dissolved Air Systerm is used in this device. It has ingenious structure, and its efficiency of dissolving air is as high as 90%. But its volume is only one-fifth of the other kind of dissolved air system. In addition, it still has the super anti-clogging ability which is incomparable;
Release effect and the mean diameter of microbubble is only between 15 to 30 microns. In addition that,this kind of dissolved air releasers also has the self-cleaning ability;
This device also applies Chained Scum Skimmer, works Smooth and reliably and skims scum efficiently.
