Product description:
Dissolved air flotation
Dissolved air flotation (DAF) is a water treatment process that
clarifies wastewaters (or other waters) by the removal of suspended
matter such as oil or solids. The removal is achieved by dissolving
air in the water or wastewater under pressure and then releasing
the air at atmospheric pressure in a flotation tank basin. The
released air forms tiny bubbles which adhere to the suspended
matter causing the suspended matter to float to the surface of the
water where it may then be removed by a skimming device.
1. Small footprint, lower energy consumption; easy operation and
simple management
2. High efficiency of air dissolving, stable treatment effects;
3. This unit uses our GFA dissolved air system with ingenious
structure. lts eficiency of air dissolving can reach up to 90%.
Compared with traditional dissolved air system, our new dissolved
air system has about one-fifth volume. What's more, it has strong
anti-clogging capacity.
4. Use new type of dissolved air releaser, high releasing degree,
the average particle size of micro bubbles is about 15-30um.
5. Use chain-plate skimmer, stable operation and high efficiency of
scraping.
Dissolved Air Flotation(DAF) consists of flotation tank, dissolved
air system, reflux pipe, dissolved air released system, skimmer
(Based on customer needs, there are combined type, traveling type
and chain-plate type to choose.), electric cabinet and so on.
Air flotation separation technology dissolved air into water at
certain working pressure. In the process, pressurized water is
saturated with dissolved air and is discharged into a flotation
vessel. The microscopic air bubbles produced by released air attach
to suspended solids and float them to the surface, forming a sludge
blanket. A scoop removes the thickened sludge. Finally, it complete
purifies the water.
Air flotation technology plays an important role in solid-liquid
separation (Simultaneously reduce COD, BOD, chroma, etc). Firstly,
mix flocculating agent into raw water and stir thoroughly. After
the effective retention time (lab determines the time, dosage and
flocculation effect), the raw water enters into the contact zone
where microscopic air bubbles adhere to the floc and then flows
into the separation zone. Under the buoyancy effects, the tiny
bubbles float the flocs to the surface, forming a sludge blanket. A
skimming device removes the sludge into the sludge hopper. Then the
lower clarified water flows into the clean-water reservoir through
the collecting pipe. Some of water are recycled to the flotation
tank for the air dissolving system, while others will be
discharged.
