1. Air flotation treatment is to inject air into the wastewater and separate it from the water as a carrier in the form of micro bubbles, so that the emulsified oil, micro suspended particles and other pollutants in the wastewater can adhere to the bubbles and float to the water surface together with the bubbles to form a three-phase mixture of foam gas, water and particles (oil). The purpose of separating impurities and purifying wastewater is achieved by collecting foam or scum. Air flotation equipment includes dissolved air flotation equipment and shallow air flotation equipment.

2. The dissolved air flotation equipment introduces new technology from Japan, using an efficient dissolved air pump to mix water and gas and dissolve them under pressure to form dissolved air water, which is then released under reduced pressure. Fine bubbles precipitate and suspended particles are efficiently adsorbed and floated up, thus achieving the purpose of solid-liquid separation.

3. The shallow air flotation equipment is designed using the "shallow theory" and the "zero speed" principle, integrating flocculation, air flotation, skimming, sedimentation, and mud scraping, and is an efficient and energy-saving water purification equipment.
