Horizontal flow dissolved air flotation machineIt is a commonly used solid-liquid separation equipment in the sewage treatment industry, which can effectively remove suspended solids, oil, and gel substances in sewage. It is the main equipment for sewage pretreatment.

The working principle of the laminar flow dissolved air flotation machine is that the dissolved air tank produces dissolved air water, which is released into the water to be treated through a pressure regulator. The air dissolved in water is released from the water, forming tiny bubbles of 20-40um. These bubbles combine with suspended solids in the wastewater, making the suspended solids have a lower density than water and gradually floating to the surface to form floating debris. There is a scraper system on the water surface to scrape the floating slag into the sludge tank. Clear water enters the clean water tank from the bottom through the overflow channel.

The laminar flow dissolved air flotation machine is widely used for the recovery of white water pulp and the reuse of clean water in papermaking; Removal of various heavy metal ions; Separation of refinery wastewater and oil pollution; Removal of impurities from tannery wastewater; Removal of chromaticity and impurities from printing and dyeing wastewater; Solid liquid separation of sludge and membrane after various biological treatments. The laminar flow dissolved air flotation machine is widely suitable for wastewater treatment in industries such as petroleum, chemical, printing and dyeing, papermaking, refining, leather, steel, mechanical processing, starch, and food.

Scope of application of laminar flow dissolved air flotation machine:

1. Used for removing suspended solids, oils, and various gelatinous substances from wastewater, such as wastewater treatment in industrial enterprises such as petrochemicals, coal mines, papermaking, printing and dyeing, slaughtering, and brewing;

2. Used for recycling useful substances, such as collecting fine fibers in papermaking wastewater.

What are the advantages of the laminar flow dissolved air flotation machine

1. The dissolved gas tank produces small bubbles with a particle size of 20-40um, which adhere firmly to the floc and can achieve good air flotation effect;

2. Low usage of coagulants reduces costs;

3. The operating procedures are easy to master, the water quality and quantity are easy to control, and the management is simple.

4. Equipped with a backwash system, the release device is not easily clogged.
