Product Description
Aerator Cavitation Air Flotation Machine CAF for Wastewater Treatment Purification
Cavitation air flotation for Sewage treatment is widely used to remove the suspended solids (SS), fat, oil and grease (FOG) in the waste water. Especially for petroleum industry and it plays an important role in oil-water separation.
In the water supply and drainage treatment process, the gas float separation technology is an effective method for the removal of tiny suspensions with a proportion close to water.

Vortex depression is a new type of suspended pollutant separation purification equipment, specially designed to remove grease, gel and suspended solids in industrial and urban sewage, is an excellent sewage treatment technology, it is through the special design of the bulk air impeller to directly and uniformly inject microbubbles into the sewage without the need for complex gas-soluble technology in advance, so there will be no blocking phenomenon, with reasonable design, easy operation, economic and reliable operation and so on.
CAF (Cavitation air flotation) is consists of aerator, flotation tank, skimmer and electric cabinet. The aerator inhales the air by the high speed rotating driven impeller. The micro bubbles released by the aerator impeller distribute to the flotation tank. Then the oil & grease are stuck together and floated to the surface by the micro bubbles. The skimmer system scraps the surface sludge to clean the water. The clean underwater would flow into the clean water tank and pump to the next process.
vortex concave air float is the latest product with the introduction of American technology. The system has the advantages of low energy consumption, high efficiency, economical operation, simple operation, low investment cost, small occupation area and so on. It is widely used in papermaking, chemical industry, printing and dyeing, oil refining, starch, food and other industries of industrial sewage and municipal sewage treatment standards.
Aerator is the main component of Cavitation Air Flotation Machine (CAF) . It uses the high speed rotation of motor to drive the impeller to rotate at high speed. When the aeration impeller rotates at high speed under water and stirs the water flow, it generates negative pressure and inhales air through the air suction hole. After the impeller at high speed in the water will bring into the air at the bottom of the pool body cutting micro air bubble formation, the coagulant and flocculant, under the joint action of suspension physical flocculation and chemical flocculation, forming a large suspension floccules, under the effect of bubble group of ascending "floccules" floating on the liquid surface scum formation, utilization of slag scraper separation from water.
Features of Vortex Concave Air Flotation
No need of reflux pump, air compressor and pressure vessel
Save operating cost, floor space and investment cost
Simple, compact and maintenance-free
Especially suit for oily wastewater treatment

Work Principle of CAF machine
The untreated sewage first enters the super filter for pretreatment, and is preliminarily purified through screening and filtration. After treatment, the sewage is pumped or self-flowed to the air floatation machine, and the appropriate flocculant is added for coagulation.
Submersible concave aerator is the use of air conveying tube at the bottom of the gas impeller of the high speed rotation in the water to form a vacuum area, the liquid surface of the air is inhaled into the water, the micro bubbles, and spiral rise to the surface of the water, the oxygen in the air also entered the water.
Due to the pressure imbalance between the gas-water mixture and the liquid, a vertical upward buoyancy force is created, bringing the suspended matter to the liquid level. In the process of rising, the microbubbles will attach to the suspended object, and the suspended object will be supported by these bubbles after reaching the liquid surface, and will be removed by radial air thrust.
Suspended objects floating on the water surface are continuously removed by the driving type (or chain type) scraper, the scraper moves along the whole liquid level, and the suspended objects are pushed from the inlet end of the air float tank to the outlet end, through the inclined metal plate into the scum tank, and the collected sludge is sent into the sludge collection tank for storage and collection. For the sinking SS, a precipitation cone is designed.
Due to the relatively slow flow rate of water, the sinking SS can be deposited in the cone without interference, and then discharged regularly. After purification, the sewage enters the overflow tank through the outlet under the metal before discharge. The water level regulation device is designed on the overflow tank to control the water level of the air floating tank, so as to ensure that the sludge scraper will not blow the sewage into the scum discharge pipe when scraping.
Advantage of Vortex Concave Air Flotation
Low investment, low energy consumption, no noise from automatic slag discharge, convenient operation and management
Mainly remove the vast majority of insoluble COD in sewage and can float (proportion less than water) SS and can sink (proportion more than water) SS.
Compared with the traditional domestic pressurized dissolving air floating system, it saves the equipment of dissolving air tank, air compressor, high-pressure water pump and so on, and the energy consumption is 1/8~1/10 of the conventional air floating system.
The system can remove the grease, glue and fiber suspended matter in sewage, reduce the BOD, COD, SS and other sewage load, and can obviously improve the color of water quality.
