Overseas Technology DAF Sewage Treatment Plant Equipment DAF

Working principle of DAF dissolved air flotation unit:

The feed water of industry wasterwater to DAF dissolved air flotation tank is often (but not always) dosed with a coagulant (such as ferric chloride or aluminum sulfate) to coagulate the colloidal particles and/or flocculants to conglomerate the particles into bigger clusters.

A portion of clarified effluent water leaving the DAF dissolved air flotation tank is pumped into a small pressure vessel (called air drum or saturator) into which compressed air is also introduced. This process saturates pressurized effluent water with air under pressure (2.5~4kg/cm²).

1. Micro bubble generation

2. Sedimentation technology

3. Counter current mechanism

4. Scum circulation and flocculation technology

5. Hypo-surface capture technology

6. Laminar flow in separation zone technology

 The dimensions and other information of Benenv DAF dissolved air flotation are as follows: 

1. Simple installation: The DAF dissolved air flotation packs will arrived at your work site assembled, which reduces installation time. If needed, specialists will be sent to assist with instruction

2. Low energy consumption: The ability to save energy is among the best in the industry

3. High productivity: The maximum water capacity is 300t/h

4. Numerous models for choice: 6 types of standard DAF dissolved air flotation models, adapted to all the requirements of various industries

5. Customizable: Equipment will be adjusted by specialized designing team to meet customer's specific needs

6. Small volume: Cover an area of 30~50m², weight less than 8 tons

7. Advanced technology: Using mutual and developed technology to enhance the water separating ability

8. Reliable manufacturing process: The engineering process is built up by professional teams with many years of manufacturing experience

The aim of DAF dissolved air flotation is to separate the fine suspended solids in water, algae and micro-floc.

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.
