DAF Oil Water Separator Prices Air Floatation Machine WWTP Integrated System

Dissolved Air Flotation Description

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.

The removal is achieved by dissolving air in the water or wastewater under pressure and then releasing the air at atmospheric pressure in a flotation tank. The released air forms tiny bubbles which adhere to the suspended matter causing the suspended matter to float to the surface of the water where it may then be removed by a skimming device.

Dagyee Dissolved air flotation price designs utilize parallel plate packing material lamellas to provide more separation surface and therefore to enhance the separation efficiency of the unit.

Dissolved Air Flotation Feature

Dissolved air pump edge bibulous the edge is inspiratory, pump pressurized mix within, gas to liquid efficient dissolving, small bubbles than 30 um.
Low voltage operation, the dissolved gas efficiency is as high as 99 percent, release rate as high as 99 percent.
Tiny bubbles and suspended particles of efficient adsorption, improve the SS remove effect.
Dissolved gas water dissolving efficiency 80-100 percent, than traditional dissolved gas floating high efficiency three times.
Pressure-capacity curve smooth, easy to achieve automatic control, easy to operate, easy maintenance, low noise.
