CAF cavitation air flotation machine
CAF cavitation air flotation machine
Product details
Introduction:
Vortex concave air flotation uses the principle of combining mechanical aeration with chemical flocculation to treat various types of wastewater with different water qualities, making it an ideal physicochemical equipment for wastewater treatment. In the treatment of wastewater with low pollutant content, the treated clean water can be recycled or discharged in compliance with standards, combined with biochemical treatment technology, and can be completely treated in compliance with standards.
This system is mainly used for the purification and treatment of industrial wastewater in industries such as papermaking, chemical, printing and dyeing, food, beer, pharmaceuticals, and slaughter.
advantage:
1. Low investment, low energy consumption, automatic slag removal without noise, and convenient operation and management.
2. Mainly removes the vast majority of insoluble COD and SS that can float (with a specific gravity lower than water) and sink (with a specific gravity greater than water) from sewage.
3. Compared with traditional pressurized dissolved air flotation systems in China, it eliminates equipment such as dissolved air tanks, air compressors, and high-pressure water pumps, and consumes 1/8 to 1/10 of the energy of conventional air flotation.
4. This system is capable of removing oil, gel like substances, and fiber suspended solids from wastewater, reducing sewage loads such as BOD, COD, SS, and significantly improving the color of water quality.
Operating characteristics:
HD-AF cavitation air flotation is an excellent innovation in sewage treatment technology equipment, with reasonable design, convenient operation, and economical operation. It directly removes solid suspended solids from wastewater and generates air flotation from air. The vortex concave aerator directly injects "microbubbles" into the sewage without the need for pre aeration, and then evenly distributes the "microbubbles" in the sewage through the diffuser impeller, so there will be no blockage during the entire operation process, and equipment such as pressure aeration, air compressor, and circulation pump are not required.
Untreated sewage first enters the aeration shell air section and is fully mixed with microbubbles. During the rising process, microbubbles bring solid suspended solids to the water surface. The scraper moves along the liquid surface to scrape the suspended solids onto the metal plate of the inclined material, and then pushes them into the sludge discharge pipeline. There is a horizontal screw propeller in the sludge discharge pipeline, which sends the collected sludge into the sludge collector. The thruster and scraper are driven by the same motor. The power is only 0.5 horsepower. After sewage purification, it will pass through the overflow tank under the inclined plate before discharge. The overflow tank is used to control the water level of the air flotation tank, ensuring that the liquid in the tank does not flow into the sludge discharge pipeline. The open throat flow pipeline extends from the aeration section along the bottom of the air flotation tank. At the same time as microbubbles are generated, the vortex concave aeration machine extends in the pool with a return pipe. At the same time, microbubbles are generated, and the vortex concave aeration machine forms a negative pressure zone at the bottom of the pool with a return pipe. This negative pressure effect will cause wastewater to flow back from the bottom of the pool to the aeration zone, and then return to the air flotation section. This process ensures that air flotation continues even with an inflow rate.
