Combination of Flotation and Flocculation Advanced Dissolved Air Flotation for Dyeing Industry Wastewater Treatment

Combination of Flotation and Flocculation Advanced Dissolved Air Flotation for Dyeing Industry Wastewater Treatment

DAF equipment is liquid/solid or liquid/liquid separation process to remove tiny suspended solids that density close to the water, colloid ,oil and grease etc. Benenv DAF equipment is an innovation combined with traditional dissolved air flotation concept and modern technology.

Brief Introduction of DAF Equipment

 A large numbers of fine and uniform bubble (5 ~ 80μm), bubbles, water, floc (oil) three-phase mixture, as a carrier, bubbles mixed with floc particles suspended in the water. Connect, adhesion, form floc with bubbles and float to the liquid surface, scraping scum to achieve separation of impurities, water purification .

The dimensions and other information of Benenv DAF equipment are as follows: 

Application Industry

 The aim of DAF equipment is to separate the fine suspended solids in water, algae and micro-floc. And DAF equipment can be used in the following industries:

l  Separate or recycle waste oil or grease in : oil exploration and refining, biodiesel, machining , food production and catering and so on.

l  High concentration organic wastewater treatment: paper, printing and dyeing, textile, leather, pharmaceutical, fermentation wastewater and so on.

l  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.

l  Farm and slaughter house wastewater treatment: cattle, pigs, chickens farm, slaughter house wastewater.

l  Manufacturing waste: electroplating, painting, etc.

l  Purification: river, landscape, recycle water and so on.

  Characteristics Advantages

Core technology of DAF equipment

l  Micro-bubble generation technology

l  Forth circulation and flocculation technology

Characteristics and Advantages of DAF equipment

l  Overall specialized, compact structure, and high performance

l  Huge markets ,high maturity, stable performance and reliable operation

l  Hydraulic load: 3 ~ 5 m³ / (m².h)

l  Maximum inlet SS concentration is ≤ 1000 mg/L

l  Automatic scum discharge, solid content can be up to 30 ~ 100 mg/L

l  Applied for the wastewater with suspended solids & floc density lighter than water or close to the water and weak precipitation phenomenon
