2. Because the treatment direction of air flotation mainly includes: mud-water separation; Oil removal, etc. Although it is mainly used for mud-water separation, its water distribution structure is different according to different water quality, different chemicals added and different emphasis on water purification. Reflux ratio; Amount of dissolved air; The requirements for operating parameters such as dissolved air pressure are also different, so there is no unified industry standard for air flotation machines at present, and air flotation machines are basically customized.
3. There are two main types of air flotation machines: horizontal flow and vertical flow. According to your water treatment capacity, both horizontal flow and vertical flow can be used. If only ordinary air flotation machine is used for PAC+PAM coagulation of low concentration and low turbidity water, the reflux ratio is10/30%; The dissolved gas pressure is 3~4 kg, the ground load is below 8, and the gas supply is above 15 cubic meter/hour.
4. The subsequent filtration treatment can be filter pressing or shallow sand filtration, which has low energy consumption, but it occupies a large area and is troublesome to maintain. Pressure filtration has high energy consumption and small floor space. Pressure filtration is recommended.

Well, this thing is just a gimmick. In fact, it is a combined structure of a horizontal air flotation tank and a gravity filter. Design according to the design specifications of air flotation tank and gravity filter. Attention should be paid to the washing and maintenance of gravity filter when the depth of water tank increases. This tells our colleagues not to ignore the old craft, and the old craft can also engage in gimmicks and play new tricks.
