Dissolved Air Flotation (DAF System) is a water treatment process that clarifies wastewater (or other water, such as river or lake) by removing the suspended solids or oil & grease. It is widely used in the waste water treatment for solid-liquid separation, it can remove the suspended solids, oil & grease and colloidal substance effectively. Meanwhile, the COD, BOD can be reduced. It's the main equipment for the waste water treatment.
DAF System mainly consists of dissolved air pump, air compressor, dissolved air vessel, rectangle steel tank body, skimmer system.
- Easy operation and simple management, convenient control the wastewater quantity and quality.
- The micro bubbles produced by the dissolved air vessel are just 15-30um, it's adhesive with flocculant strongly to achieve better flotation effect.
- Unique GFA dissolved air system, high efficiency of air dissolving can reach 90%+, strong ability for clogging.
- Chain-plate type skimmer, stable operation and high efficiency to scrap.
The dissolved air water produced by GFA system is pumped into the air releaser by reducing the pressure. 15-30um micro bubbles from the air releaser would adhere to the suspended solids make them lighter than water, then the solids combined with micro bubbles can float onto the surface to form a scum layer that would be scrapped by the skimmer system into the sludge tank. The lower clean water flows into the clean water tank. At least 30% of the clean water is recycled for GFA system while other is discharged or pumped to next process.

Frequently Asked Questions
What is the primary function of a DAF system?
The primary function of Dissolved Air Flotation (DAF) is solid-liquid separation. It effectively removes suspended solids, oils, greases, and colloidal substances from wastewater by attaching them to micro-bubbles.
What materials are used for the tank body?
Depending on the specific industrial requirements and the nature of the wastewater, we offer tanks made of Carbon Steel (typically coated), SS304, or SS316L stainless steel for maximum corrosion resistance.
How efficient is the air dissolving system?
Our unique GFA dissolved air system is highly efficient, capable of reaching an air dissolving rate of 90% or higher, which ensures superior flotation performance.
Can the capacity be customized for large industrial projects?
Yes. While our standard models like the GF-150T handle 150m³/hour, we provide customized specifications to meet the unique treatment capacity requirements of any facility.
What is the size of the micro-bubbles produced?
The system produces micro-bubbles ranging from 15 to 30 microns. This optimal size ensures strong adhesion to flocculants and solids for efficient removal.
Is the skimmer system stable?
Yes, the system utilizes a chain-plate type skimmer designed for stable operation and high efficiency in scraping surface scum into the sludge collection tank.
