DAF dissolved air flotation for oil and grease treatment
Dissolved Air Flotation is the process of removing grease, oils and other fineSuspended solids and reduces COD and BOD device. the use of air bubble flotation. Air was dissolved into water, the air -saturated water generated from dissolved air micro bubbles attach to the surface of solids,The light of solids(less dense than water)lifting them to the surface.distributed over the whole tank width,make suer optimum phase separation. Mechanical skimmer remove the floating sludge layer and thepurified wastewater discharges to sewer.
Yosun dissolved air flotation solutions provide high-quality, high-capacity, and efficient clarification.
Application in Various 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:
l Separate or recycle waste oil or grease in : oil exploration and refining, biodiesel, machining , food production and catering and so on.
lHigh concentration organic wastewater treatment: paper, printing and dyeing, textile, leather, pharmaceutical, fermentation wastewater and so on.
lBiochemical 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.
lPurification: river, landscape, recycle water and so on.

1.What is the capacity of the range of DAF dissolved air flotation systems?
The range of DAF dissolved air flotation system is specially designed for industrial applications that usually experience high solid loading. We manufacture standard sizes,most suitable model and dissolved air recycle system to suit specific wastewater characteristics.
2.How to choose the right model to get a quote?
According to the amount of wastewater treatment, please select the appropriate model according to our selection table, or contact us directly to obtain the appropriate model and quotation.
3.Can the dissolved air flotation system handle variable load and flows?
It depends. In the application without chemicals, DAF dissolved air flotation system can operate under any flow rate and solid load and effectively treat wastewater to achieve its design capability. If chemicals are being dosed,on the contrary, it will adversely affect the chemical process.
4.Do I need to dose chemicals into the wastewater?
Dosing of chemicals into the wastewater upstream of the DAF dissolved air flotation system will improve the performance of the system. Whether it is necessary to dose chemicals depends on the water quality that is required.
5.How much sludge will the DAF dissolved air flotation system generate?
You can estimate the amount of sludge that will be generated by multiplying the solids load by the daily flow or contact me.
6.What is the performance of the DAF dissolved air flotation system in terms of pollutant removal?
The DAF dissolved air flotation system can remove over 99% of solids and grease which will result in quite significant reductions in BOD and COD. Nutrients and metals can also be removed using the DAF dissolved air flotation process.
7.Does the DAF dissolved air flotation system require much power?
The power demand for the actual DAF dissolved air flotation system is minimal. You can refer to our selection table or contact us.
8.Can the DAF dissolved air flotation system system handle large solids?
It can, but large solids can cause blockages and increase the chances of sedimentation occurring. We recommend the installation of a 1 -2 mm screen be installed upstream of the DAF dissolved air flotation system.For information on our range of screens, please check our website or contact us.
9.Is the DAF dissolved air flotation system easy to maintain?
Yes, the system can often be maintained by in-house personnel. The DAF dissolved air flotation system rarely fails, if you need support services pls contact us.
10.How long is the after-sale warranty period of DAF dissolved air flotation system?
