Application Industry

The aim of dissolved air flotation is to separate the fine suspended solids in water, algae and micro-floc. And dissolved air flotation can be used in the following industries:
1、 High concentration organic wastewater treatment: paper, printing and dyeing, textile, leather, pharmaceutical, fermentation wastewater and so on.
2、Biochemical effluent liquid separation: the anaerobic effluent solid-liquid separation, aerobic (activated sludge process, contact oxidation, filter) biochemical water solid-liquid separation, the secondary settling tank Effluent treatment and so on.
3、 Farm and slaughter house wastewater treatment: cattle, pigs, chickens farm, slaughter house wastewater.
4、 Manufacturing waste: electroplating, painting, etc.
5、 Purification: river, landscape, recycle water and so on.
6、Separate or recycle waste oil or grease in : oil exploration and refining, biodiesel, machining , food production and catering and so on.

Characteristics Advantages

Core Technology of dissolved air flotation for water clarification
l Micro-bubble generation technology
l Forth circulation and flocculation technology

Characteristics and Advantages of dissolved air flotation for water clarification

1、Overall specialized, compact structure, and high performance
2、 Huge markets ,high maturity, stable performance and reliable operation
3、 Hydraulic load: 3 ~ 5 m3 / (m2.h)
4、 Maximum inlet SS concentration is ≤ 1000 mg/L
5、Automatic scum discharge, solid content can be up to 30 ~ 100 mg/L
6、 Applied for the wastewater with suspended solids & floc density lighter than water or close to the water and weak precipitation phenomenon.
