Wastewater Treatment DAF Unit Dissolved Air Flotation System
DAF system dissolved air flotation units for waste water treatment plant is an efficient flotation method for water clarification.The term refers to the method of producing flotation by dissolving air in the water under pressure and then releasing the pressure. When the pressure is released the solution becomes supersaturated with air as millions of small bubbles form. These bubbles attach to any particles in the water causing their density to become less than that of water. The particles then rapidly float to the surface for collection and removal, leaving the clarified water behind.
DAF is a proven, and effective physical-chemical technology commonly used for many industrial and municipal applications,including :
•Product recovery and reuse
•Pretreatment to meet sewer discharge limits
•Pretreatment to reduce loading on downstream biological systems
•Polishing of biological treatment effluent
•Removing silt and grease from industrial water
•Meat, poultry, and fish processing
•Dairy industry
•Petrochemicals
•Pulp and paper
•Food and beverage

The Benefits Of Using DAF Systems
There are numerous benefits to using DAF systems for water treatment. These include:
High efficiency
DAF systems are highly effective in removing a wide range of pollutants from water. They are capable of removing up to 95% of suspended solids, oils, and grease from water.
Cost-effective
DAF systems are more cost-effective than other water treatment methods, such as chemical precipitation and sedimentation. They are also more energy-efficient, as they use less energy to create the air bubbles than other methods.
Easy to maintain
DAF systems are simple to maintain and require minimal operational attention. They are also easy to operate, making them ideal for use in remote locations where maintenance and repair services may not be readily available.
Environmentally friendly
DAF systems are environmentally friendly, as they do not produce any harmful by-products or discharge pollutants into the environment.
The Application Of DAF Systems
Poultry and slaughterhouses
Petrochemical industry
Cosmetic wastewater
Convenience food production
Oil and fat refineries
Industrial kitchens and canteens
Meat, fish processing and packing
FAQ
Q: What is the capacity of the range of DAF dissolved air flotation systems?
A: 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.
Q: How to choose the right model to get a quote?
A: 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.
Q: Can the dissolved air flotation system handle variable load and flows?
A: 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.
Q: Do I need to dose chemicals into the wastewater?
A: 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.
Q: How much sludge will the DAF dissolved air flotation system generate?
A: You can estimate the amount of sludge that will be generated by multiplying the solids load by the daily flow or contact me.
Q: What is the performance of the DAF dissolved air flotation system in terms of pollutant removal?
A: 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.
Q: Does the DAF dissolved air flotation system require much power?
A: The power demand for the actual DAF dissolved air flotation system is minimal. You can refer to our selection table or contact us.
Q: Can the DAF dissolved air flotation system system handle large solids?
A: 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.
Q: Is the DAF dissolved air flotation system easy to maintain?
A: 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.
Q: How long is the after-sale warranty period of DAF dissolved air flotation system?
A: The warranty period is 24 months after acceptance or 26 months from the data of delivery.
