Stainless steel dissolved air flotation for oil waste water treatment

Dissolved air flotation (DAF) is a water treatment process that clarifies wastewaters (or other waters) by the removal of suspended matter such as oil or solids. 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 basin. The released air forms micro or nano 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.

1. Flow rate of one set: 1-300 m³/h.
2. Recycle flow dissolved air flotation.
3. High efficiency pressurization system providing high quantity dissolved-air water to create large
quantities of small bubbles.
4. Custom design on different dissolved air flotation equipment and recycle flow ratio according to the type of wastewater and treatment requirement to achieve target removal effect and stability.
5. Adjustable stainless steel chain type skimmer to suit the different quantity of sludge.
6. Integrated coagulation tank and or flocculation tank and cleaning water tank(as optional)is
available to save the space and cost.
7. Automatic and remote controllable.
8. Material of construction: carbon steel epoxy painted, carbon steel FRP line, SS304/SS316L

Dissolved air flotation Specifications:

• High TSS removal efficiency: 96%~99%
• High hydraulic load: up to 80m3/(m2.h)
• High sludge load: up to 70kg/(m2.h)
• Small footprint: 1/5 of conventional DAF
• Less energy and chemical consumption
• High sludge concentration: up to 5% solid content

Dissolved air flotation machine package wastewater treatment plant is a water treatment process that clarifieswastewaters (or other waters) by the removal of suspended matter such as oil or solids. 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 basin. 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.

Dissolved air flotation is very widely used in treating the industrial wastewater effluents from oil refineries, petrochemicaland chemical plants, natural gas processing plants, paper mills, general water treatment and similar industrial facilities
