Dissolved Air / Gas Flotation Separators. DAF system with lamella separator & type flocculator. Dissolved Air Flotation (DAF) System : Dissolved Air Flotation (DAF) is aPhysio-Chemical Treatment where air is intimately contacted with an aqueous stream at high pressure,dissolving the air. The pressure on the liquid is reduced through a back pressure valve, thereby releasing micron-sized bubbles that sweep …

Review Concerns and Requirements of the NewDissolved Air Flotation SeparatororSeparationSystem With the Engineer / Designer List all provisions that need to be considered to ensure the new system will be accessible for maintenance, will meet site specific area classifications (ie: seismic and explosion proof area classifications, etc.) and will meet all regulatory and effluent discharge requirements.
Dissolved Air Flotation Clarifiers. The M.W.Watermark Dissolved Air Flotation (DAF) Clarifier is designed to remove suspended solids, oils, grease, metals and non-soluble BOD from a waste stream. Clarification rates as high as97% removal, with proper chemical pretreatment, are common.
GFT™Flotation. GFT™ saves money and time. It quickly processes single-tank volumes as high as 750,000 BWPD to target outputs of 10 ppm.GFT combines the design of an API tank andflotationvessel into a single unit, greatly reducing capital and tie-in costs and achieving retention times of about one hour versus 4-6 hours with typical skim tanks.
Description Dissolved air flotation (DAF) is a proven andeffective physical/chemical technology for treating a variety of industrial and municipal process and wastewater streams. DAF systems are commonly used for the removal of oils & greases and suspended solids to meet a variety of treatment goals including: Product recovery and reuse
Dissolved gas designs take a portion of the treated water effluent and saturate the water with natural gas in a contactor. The higher the pressure the more gas can be dissolved in the water. Most units are designed for a 20 to 40 psig contact pressure. Normally, 20% to 50% of the treated water is recirculated for contact with the gas.

Adissolved gas flotationsystem for treatment of wastewater or contaminated water and having an improved flow pattern wherein the subnatant discharge outlet and the inlet distribution structures are located adjacent one another. Such a structural design takes advantage of the fluid flow patterns within the tank to maximize the effect of the air bubbles in separating solids from the fluid.
In my prior Patent No. 2,746,605 entitled, Treatment of Liquids by Means ofDissolvedGases, issued May 22, 1956, I described generally the process offlotationseparation whereby a mixture of immiscible liquids, for example, are directed into aflotationcell with air or othergas dissolvedand entrained therein.
Normally, 20% to 50% of the treated water is recirculated for contact with thegas. Thegassaturated water is then injected into theflotationtank as shown in Figure 7-13. Thedissolved gasbreaks out of solution in small diameter bubbles that contact the oil droplets in the …
Jun 02, 2019· Among the most common include thedissolvedairflotationsystem, the water oilseparatorsystem, the aerobic treatment system, and the inducedgas flotationsystem. These water treatment systems vary from one another in both their principles of operation and the purposes for which they were designed.
Dissolvedairflotation(DAF) is a proven and effective physical/chemical technology for treating a variety of industrial and municipal process and wastewater streams. DAF systems are commonly used for the removal of oils & greases and suspended solids to meet a variety of treatment goals including:
DissolvedAirFlotationsystems effectively remove TSS, FOG, and other pollutants from wastewater. Conceptually, the DAF process is simple – tiny bubbles attach to solid contaminants causing them to float and then sludge is skimmed off the surface of the water – but designing a DAF system for a real-world application isn’t quite as simple.

Oil WaterSeparator--DissolvedAirFlotationUnit (DAF Machine)DissolvedAirFlotationmachine, short for DAF, it is main machine used to remove the TSS and oil. It is widely used in the pre-treatment process for the wastewater treatment. The TSS and oil removal rate can reach above 90%, at the same time it can remove some COD around 30~50%.
