Water treatment method and basic principle of air flotation machine

The air floatation machine is suitable for the treatment of low turbidity, high water content of organic compounds and low oil content, so that the particle size and content of the residue in the water and its water index value reach all normal. There are many ways to treat the purified water of the dissolved air floatation machine, one is the working pressure dissolved air floatation machine.

This new water treatment technology is to introduce many ultra-fine bubbles released from the working pressure dissolved gas water into the water to be treated, and use the buoyancy of the bubbles attached to the liquid residue to reach the goal of rapid separation of solid and liquid, and development of scum extraction level.

Dissolved air releaser is an important installation in water purification system of working pressure dissolved air floatation machine. If the working pressure dissolved air water goes through the installation of pressure reducing and energy dissipation, it can release a lot of ultra-fine bubbles. The advantages and disadvantages of the characteristics of the releaser, the amount of bubbles released when touching, the ultra-fine degree of bubbles and the distribution law of bubble specifications, etc., will immediately endanger the actual effect and electromagnetic energy consumption of the air flotation machine method for water purification.

The key basic principle of the air flotation machine is to add medicine to the waste water to make it reflect the flocculent chemical substances, introduce a lot of bubbles into the waste water together, so that the bubbles and floccules will float to the surface of the liquid, and then discharge them according to the slag scraper of the supporting facilities, and the cold water will be discharged from the outlet directly below.

Air floatation equipment is a kind of wastewater treatment equipment which is widely used at present. It causes a lot of micro bubbles in the water, which makes the gas adhere to the suspended solid particles in the form of micro bubbles with high and wide ratio dispersion, resulting in the situation that the relative density is lower than that of water. It floats on the river surface by using the basic principle of buoyancy, so as to realize the water purification equipment with solid-liquid separation. It is often used in water supply and drainage, chemical wastewater and domestic sewage treatment.
