Electrocoagulator DAF System Dissolved Air Flotation Septic Tank Sewage Wastewater Treatment
DAF dissolved air flotation 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 of us 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.
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
