Dissolved Air Flotation Equipment

Dissolved Air Flotation Equipment

Dissolved Air Flotation Equipment is a Sewage Treatment equipment that utilizes the buoyancy generated by bubbles to separate suspended particles from water.
Working Principle
Dissolved air flotation (DAF) equipment works by introducing fine air bubbles into a liquid (usually water) to attach to suspended particles and create buoyancy, causing the particles to float to the surface for removal. The process first pressurizes and saturates the liquid with air, then rapidly depressurizes it, releasing microbubbles attached to the contaminants. As the bubbles rise, they bring particles to the surface, creating a layer of sludge that can be skimmed off. The method effectively separates solids and oil from liquids, making it suitable for a variety of industrial and municipal wastewater treatment applications.

Besides,regarding the Wastewater Treatment Equipment,except for the Air Flotation Machine,we also produce Micro Drum Filters,Rotary Mechanical Grille Cleaning Machine,Screw Press Sludge Dewatering Machine,Integrated Buried Sewage Treatment Equipment,etc.

Application of Dissolved Air Flotation Equipment
1. Treatment of papermaking wastewater The production process of the papermaking industry generates a large amount of wastewater, which contains a large amount of pollutants such as suspended solids, colloidal substances, and fats. Air flotation machines can generate bubbles to float these pollutants on the water surface, and then treat them with other equipment to achieve the goal of purifying water quality.

2. Food processing wastewater treatment A large amount of wastewater is generated during food processing, which contains a large amount of pollutants such as suspended solids, fats, and proteins. Air flotation machines can generate bubbles to float these pollutants on the water surface, and then treat them with other equipment to achieve the goal of purifying water quality.

3. Treatment of textile printing and dyeing wastewater The textile printing and dyeing industry generates a large amount of wastewater in the production process, which contains a large amount of pollutants such as suspended solids, dye pigments, and oils. Air flotation machines can generate bubbles to float these pollutants on the water surface, and then treat them with other equipment to achieve the goal of purifying water quality.

4. Petrochemical wastewater treatment The production process in the petrochemical industry generates a large amount of wastewater, which contains a large amount of pollutants such as suspended solids, oil substances, and chemical additives. Air flotation machines can generate bubbles to float these pollutants on the water surface, and then treat them with other equipment to achieve the goal of purifying water quality.

Advantages of Dissolved Air Flotation Equipment
1. Efficient removal of suspended solids: Air flotation machines can efficiently remove suspended solids in wastewater, including fibers, pigments, and other solid particles in papermaking wastewater, effectively purifying wastewater.
2. Strong adaptability: The air flotation machine has good adaptability to different substances in wastewater and can treat papermaking wastewater of different concentrations and types.

3. Energy conservation and environmental protection: Compared to traditional sedimentation or filtration processes, air flotation machines usually have higher processing efficiency and lower energy consumption, which is beneficial for energy conservation, emission reduction, and environmental protection.

4. Easy to operate: The operation of the air flotation machine is relatively simple, easy to maintain, and can achieve automated control, reducing labor costs and operational difficulties
