High-efficiency dissolved air flotation machine is mainly used for "solid-liquid" or "liquid-liquid" separation. A large number of fine bubbles are generated in the water through the dissolved air and release system, which make them adhere to the solid or liquid particles in the wastewater with a density close to that of water, causing the overall density to be less than that of water, and relying on buoyancy to make them rise to the water surface, thereby achieving the purpose of "solid-liquid" or "liquid-liquid" separation.
Air flotation machines have a wide range of functions and are mainly used in the following aspects:
1. Solid-liquid separation: Air flotation machines can float suspended matter, impurities, oils and other substances in wastewater to the surface to achieve efficient separation. This makes air flotation machines widely used in sludge treatment, papermaking wastewater treatment, petrochemical wastewater treatment and other fields in the field of water treatment.
2. Adsorption: Air flotation machines use tiny bubbles as carriers to adsorb harmful substances such as heavy metal ions, organic matter and dyes in water. After these substances are adsorbed, they are effectively removed through subsequent treatment processes, thereby reducing the pollution of wastewater to the environment.
3. Improve water quality: Air flotation machines can remove suspended matter, impurities and odors in water to improve water quality. This makes air flotation machines widely used in drinking water treatment, swimming pool water treatment and other fields.
4. Reduce COD: Air flotation machines can reduce the chemical oxygen demand (COD) in wastewater by removing organic matter in water. This is of great significance for the effluent quality control of sewage treatment plants.
5. Recycling useful substances: The air flotation machine can recycle useful substances such as oils, heavy metal ions and other substances in wastewater to achieve effective utilization of resources. This can not only reduce the pollution of wastewater to the environment, but also bring economic benefits to the enterprise.
In short, as an efficient water treatment equipment, the air flotation machine has a wide range of principles and functions, and plays an increasingly important role in the field of water treatment. With the continuous improvement of environmental protection awareness and the continuous innovation of technology, the air flotation machine will be more widely used and developed.
