Industry Wastewater Treatment Dissolved Air Flotation Solid Liquid
Separator Remove
The dissolving gas tank of the advection-type dissolved air
flotation machine generates dissolved gas water, and the dissolved
gas water enters the water to be treated through the release tube.
The small bubbles slowly rise and adhere to the impurity particles
to form a floating body with a specific gravity smaller than that
of water and float on the water surface. Scum is formed,and then
the scum is removed by a slag scraper.The scum is removed from the
slag scraper, sinks to the vertebral body more than the water ratio
,and is intermittently discharged into the sludge pool.
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
Dissolved Air Flotation Features
1 Small footprint, Low energy consumption; Easy operation; Simple
management;
2 Efficient dissolved air; Stable treatment effect ; Full-automatic
operation;
3 GFA Type Dissolved Air Systerm is used in this device. It has
ingenious structure, and its efficiency of dissolving air is as
high as 90%. But its volume is only one-fifth of the other kind of
dissolved air system. In addition, it still has the super
anti-clogging ability which is incomparable;
4 Release effect and the mean diameter of microbubble is only
between 15 to 30 microns. In addition that,this kind of dissolved
air releasers also has the self-cleaning ability;
5 This device also applies GLG Type Chained Scum Skimmer, works
Smooth and reliably and skims scum efficiently.
Dissolved air flotation Specifications:
- High TSS removal efficiency: 96%~99%
- High hydraulic load: up to 80m3/(m2.h)
- High sludge load: up to 70kg/(m2.h)
- Small footprint: 1/5 of conventional DAF
- Less energy and chemical consumption
- High sludge concentration: up to 5% solid content
Dissolved air flotation machine package wastewater treatment plant
is a water treatment process that clarifieswastewaters (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.
Dissolved air flotation is very widely used in treating the
industrial wastewater effluents from oil refineries,
petrochemicaland chemical plants, natural gas processing plants,
paper mills, general water treatment and similar industrial
facilities
