Cavitation Air Flotation Machine, Wastewater Treatment with CAF System

If you’re looking for a machine to remove suspended matter, grease and colloids from industry sewage and civil sewage, this cavitation air flotation machine is your best choice. With the help of flocculants, the suspended matters and organic pollutants can be removed to the greatest extent. This type of cavitation air flotation machine is usually used in paper industry and it can recycle the fiber in the sewage. Cavitation air flotation machine is mainly composed of box, aerator, and sludge scraper system. Without pressure vessels, air compressors and circulating pumps, the cavitation air flotation machine can reduce the consumption of electric energy.

The chain and sprocket wheel of the scraper device
The chain and sprocket wheel of the sludge scraper of the cavitation air flotation machine produced by BETTER EPT are made of nylon material, which makes the chain and sprocket wheel good mechanical strength, wear resistance and shock absorption.

CAF aerator
The CAF aerator produced by BETTER EPT is made of carbon steel. You can also choose the aerator made of stainless steel material, which will make the aerator more corrosion resistant and can produce more compact bubbles.

The cavitation air flotation machine is mainly used for solid-liquid or liquid- liquid separation. The pollutants in the sewage are divided into dissolved organics and insoluble substance. With the addition of coagulant and flocculants, the dissolved substances can be converted into insoluble substances. By injecting a large number of microbubbles in the sewage and with the bubbles adhering to the pollutants, the pollutants in the sewage will float to the surface under the reaction of buoyancy. And after the sludge is discharged by scrum removal system, the purpose of solid-liquid or liquid-liquid separation can be achieved.

• The removal rates of petroleum pollutants and suspended solids are over 80 percent, and the removal rates of BOD and COD are up to 60 percent. Because aeration can increase the content of dissolved oxygen in sewage, which can promote the oxidation of sulfides and reduce the sulfur content in sewage.
• The cavitation air floatation machine is composed of three parts, box, aerator and sludge scraper system. Without complex equipment and the machine are easy to control, so the manual operation and maintenance work is very few, which reduces labor and maintenance costs.
