Large scale horizontal flow dissolved air flotation machine

Large scale horizontal flow dissolved air flotation machineSolid liquid separation is a common method in the wastewater treatment manufacturing industry, which can effectively remove suspended solids, vegetable oils, and strong adhesives from wastewater. It is a key machine equipment in the early stage of wastewater treatment and an excellent auxiliary machine equipment for wastewater treatment and reuse.

Large scale horizontal flow dissolved air flotation machineScope of Application

1. Removing solid suspended solids, oil, and various colloidal substances from wastewater of other industrial enterprises such as petrochemicals, coal mines, papermaking, printing and dyeing, slaughtering, and brewing;

2. Used for recycling useful substances, such as collecting fibers from white water in papermaking.

Working principle of horizontal flow dissolved air flotation machine

The dissolved gas tank forms dissolved water, which is released into the water to be treated according to the depressurization of the release device. The air dissolved in water is released from the water, forming a 20-40 micron microbubble that combines with suspended solids in the wastewater, resulting in less suspended solids than water and gradually floating to the surface to form floating debris. There is a scraper system on the water surface, and the floating debris is scraped into the silt pool. Clear water enters the clean water tank from the bottom through the overflow tank.

The function of the advection air flotation sewage treatment device

1. Advection air flotation has a high unit flotation capacity and high utilization rate of dissolved air, making it suitable for treating wastewater with particularly high suspended solids, with a maximum concentration of 20000mg/L. Paper water with a floating content of up to several thousand millimeters/L can be easily used with this device.

2. Capable of separating floating objects ranging from 1UM-10UM, such as algae.

3. It can separate metal hydroxides with high specific gravity, such as iron, copper, chromium, zinc, etc. If copper containing wastewater with a concentration of hundreds to thousands of mg/L is separated, a single air flotation will result in a concentration of less than 10mg/L.

4. This equipment is used in the fields of papermaking, food, printing and dyeing, lifespan, steel, thermal power plants, etc. The processing effect is better than industrial equipment, and the protein recovery rate in the starch industry reaches 60% of the protein content, achieving the effect of one product. It can be used for the separation of naphthalene flakes in coking cooling water, separation of various tar in coking mixed water, extraction of phenols, recovery of solvent oil, removal of oil stains, COD, SS, etc.
