Vortex concave air flotation sewage treatment equipment adopts the principle of combining mechanical aeration and chemical flocculation to treat various types of sewage with different water quality, and is an ideal physical and chemical treatment equipment for sewage. In the treatment of some sewage with light pollutant content, the treated clean water can be recycled or discharged up to the standard. If it is combined with biochemical treatment technology, it can be treated up to the standard. Vortex concave air flotation is an excellent sewage treatment technology with reasonable design, convenient operation and economical operation. It generates air bubbles from the air and directly removes suspended solids from wastewater. The vortex concave aerator injects "micro-bubbles" directly into the sewage without dissolving air in advance, and then distributes the "micro-bubbles" evenly in the sewage through the diffuser impeller, so there will be no clogging during the entire operation. The vortex concave air flotation machine is mainly composed of a box, an aerator, and a mud scraping system, and does not require pressure dissolved air, air compressors, and circulation pumps.
