1. Overview of dissolved air flotation Machine:
Dissolved air flotation machine is a new high-efficiency dissolved air flotation machine newly developed by our company. This dissolved air flotation machine is specially designed to remove grease, colloid and suspended solids in industrial and municipal sewage. By pressurizing the return water and air, the air is dissolved into the water to generate tiny bubbles, and the dissolved air is released through the releaser. For different wastewaters, adding appropriate flocculants and coagulants can effectively remove grease, suspended solids removal rate, COD, BOD, etc. The equipment has the characteristics of low operating cost, high work efficiency and simple operation and maintenance.
2. Working principle of dissolved air flotation machine:
The working principle of the dissolved air flotation machine is very advanced. The container system is a key part of the entire air flotation equipment, and the diameter and number of bubbles generated by the dissolved air system directly affect the air flotation effect. The air-dissolving cylinder is also the key part of the air-dissolving system. The air compressor enters the air-dissolving cylinder, and the special device in the air-dissolving cylinder pre-smashes the bubbles input into it, and fully dissolves the air into the reflux water under pressure to form a belt. Dissolved water with tiny bubbles, the diameter of which is between 5-20 microns. After the dissolved air and water flow out of the dissolved air cylinder, they are instantly released through the releaser, and dissolve with the sewage in the air flotation tank to form a milk-like mixture.
The biggest advantage of the dissolved air flotation machine is that it is ready to use. As long as the pressure of the dissolved air cylinder is controlled at about 3-4kg/cm2, there is no need to adjust any valves, air compressors and return pumps. When starting up, as long as the return pump and air compressor are turned on, the equipment can run smoothly by itself without manual duty. The dissolved air cylinder adopts the air crushing and dissolving system newly developed by our company, which is small in size, low in power consumption, and high in dissolved air efficiency. There is no problem that the dissolved air efficiency is affected by a long time. The release device is also a release device developed by our company, which can achieve no blockage and trouble-free operation. The residence time of the dissolved air flotation machine is shortened, so the floor space is reduced, and the equipment investment cost and operating cost are greatly reduced. The air flotation machine has replaced the traditional dissolved air flotation machine, traditional jet air flotation, etc., and has been widely used in advanced wastewater treatment.
