DISSOLVED AIR FLOTATION
PRODUCT INTRODUCTION
-
Dissolved Air Flotation (DAF) 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.
FEATURES
- Flow rate of one set: 100m³/h.
- Recycle flow dissolved air flotation.
- High efficiency pressurization system providing high quantity dissolved-air water to create large quantities of small bubbles.
- Custom design on different dissolved air flotation equipment and recycle flow ration according to the type of wastewater and treatment requirement to achieve target removal effect and stability.
- Adjustable stainless steel chain type skimmer to suit the different quantity of sludge.
- Integrated coagulation tank and or flocculation tank and cleaning water tank(as optional) is available and remote controllable.
- Automatic and remote controllable.
-
Material of construction: carbon steel epoxy painted, carbon steel FRP line, stainless steel SS304/SS316L.
APPLICATION
- DAF is a proven, and effective physical-chemical technology commonly used for many industrial and municipal applications, including:
- Product recovery and reuse
- Pretreatment to meet sewer discharge limits
- Pretreatment to reduce loading on downstream biological systems
- Polishing of biological treatment effluent
- Removing silt and grease from industrial water
- DAF is used extensively in the following industries:
- Meat, poultry and fish processing
- Dairy industry
- Petrochemicals
- Pulp and paper
