Compact DAF Unit - Small-Scale Wastewater Treatment for Manufacturing Plants

Dissolved Air Flotation Description

Oil Water Separator Wastewater Plant Treatment DAF Dissolved Air Flotation is an efficient flotation method for water clarification. The term refers to the method of producing flotation by dissolving air in the water under pressure and then releasing the pressure. When the pressure is released the solution becomes supersaturated with air as millions of small bubbles form. These bubbles attach to any particles in the water causing their density to become less than that of water. The particles then rapidly float to the surface for collection and removal, leaving the clarified water behind.

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.
