Dissolved Air Flotation (DAF) is a physical chemical separation technique used to remove suspended solids and fats, oils and grease from the wastewater.
Aerofloat has patented DAF technology in its AeroDAF, which has combined proven traditional DAF principles with world-first patented design elements to make a truly innovative product.
The AeroDAF uses a unique tank with a 60 degrees conical bottom and conical top and a patented hydraulic float removal system to funnel waste float material from the top of the tank. Unlike traditional DAFs, mechanical scrapers are not required, resulting in a compact, mechanically simple and more affordable solution.
The waste material is removed from the enclosed tank by using the hydraulics on the incoming feed stream. Most industrial waste plants will require some pre-treatment by screening, blending, hydraulic balancing and pH correction.
