TPZF combined air flotation Machine consists of air floatation tank, dissolved air system, dissolved air return pipeline, dissolved air water release device, scraping device (combined, driving and chain plate according to user needs) and electric control cabinet. In the water supply and drainage treatment process, solid and liquid separation technology and machine are one of the key projects. 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.

The equipment is suitable for 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 (The treatment capacity is 30%-50% of machines capacity), etc.

Air-floating separation technology means that air and water are dissolved in water under a certain working pressure, and the air is dissolved in a state of saturation. Then, the formed pressure-dissolved water is released by decompression, and a large amount of fine bubbles are generated. It is in full contact with the suspended flocs in the water, so that the suspended flocs in the water adhere to the micro-bubbles, and float to the surface with the bubbles, forming into scum and then scraping it off, thereby purifying the water.
