Air flotation machine to treat high-concentration organic wastewater conditions

Source:     Time:24 September 2020

In sewage treatment, air flotation machines are used in the separation of solid-liquid or liquid-liquid wastewater, and are indispensable treatment equipment in the treatment of high-concentration, refractory organic wastewater. It is to pass highly dispersed tiny bubbles into the wastewater, and use the bubbles as a carrier to poison the pollutants in the self-attached wastewater to make the density less than water and float on the water surface, and finally achieve the purpose of removal. At this stage, it is often used in the following aspects:
1. Separation of suspended oil and emulsified oil in petroleum and chemical wastewater;
2. Recycling useful substances in wastewater, such as the recovery of pulp fibers and fillers in wastewater from paper mills;
3. Replace the secondary settling tank to separate and concentrate the remaining activated sludge;
4. Separation and recovery of pollutants in molecular or ionic state, such as surface-active substances and metal ions.

The treatment process of the air flotation machine includes steps such as the generation of tiny bubbles, the adhesion of tiny bubbles and pollutants, and the floating separation. The use of air flotation machine processing technology must meet three basic conditions, that is, the treated pollutants in the wastewater must be in a suspended state, and enough fine bubbles, bubbles and suspended particles in the wastewater must be adhered.

ENVSET air flotation machine combines the three basic conditions required for the realization of air flotation, and can solve the problem of high-concentration organic wastewater treatment. 


In addition to being used in the treatment of high-concentration organic wastewater, ENVSET air flotation machines can also be used in wastewater treatment processes in a variety of industries, such as: food, pharmaceuticals, textile printing and dyeing, semiconductors, machinery, steel, chemicals, aquaculture, etc. Algae is also applicable, as well as sea water desalination.
