Wastewater Treatment

DESCRIPTION：

Air flotation is one of the most effective methods for the removal of tiny suspended particles with a specific gravity close to that of water. It’s used to remove SS, oil&grease and other substances, reduce COD and BOD, and lessen the burden of subsequent treatment in industrial wastewater treatment, such as white water pulp recovery and water reuse of paper industry, removal of various heavy metal ions, refinery wastewater, oil pollution separation, impurities in tannery wastewater, color and impurities of printing and dyeing wastewater, various biological treatment, biological mud film Solid-liquid separation, sludge concentration, etc.

APPLICATION：

• Municipal water and wastewater treatment plants

• Plastic recycling

• Textile industry dyeing

• Tannery leather

• Slaughter breeding

• Agricultural/fishery community

• Food/beverage production

• Dairy farming/Meat processing

• Chemical manufacturing

• Other(paper manufacturing, oilfield associated water accompanied with crude oil mining, etc.)

WORKING PRINCIPLE：

The bubble liquid generated by the multiphase flow pump enters the air flotation reaction tank, and the microbubbles are adhered to the suspended solids particles as the carrier. By using the density difference between the air and the liquid, the pollutants float to the water surface to form scum. The scum is scraped by the scum scraping mechanism to remove oil and suspended solids and realize solid-liquid separation.

FEATURES：

• The air flotation equipment using Germany original imported multiphase flow pump, in the process it can achieve a very perfect effect, when the liquid and air is sucked from the inlet of the pump, air in a highly dispersed state achieves a complete mix with liquid, the solubility of the liquid dissolved air can reach 100% saturation state, the air exists in the microbubble dispersion state in the liquid, the average diameter of the bubble ≤ 26 microns;

• Liquids with air content of up to 30% can be transported stably;

• Eliminating the need for compressor, pressure vessel, releaser, control system and valve, centrifugal pump) compared to conventional air flotation systems, which are greatly simplified and more reliable.
