Dissolved Air Flotation (DAF) systems are designed to remove suspended solids (TSS), biochemical oxygen demand (BOD 5), and oils and greases (O&G) from a wastewater stream. Contaminants are removed through the use of a dissolved air-in-water solution produced by injecting air under pressure into a recycle stream of clarified DAF effluent.
Dissolved air flotation (DAF) is a water treatment process that clarifies wastewater by removing suspended 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.
The Dissolved Air Flotation (DAF) process has been used extensively for wastewater treatment to remove suspended matter from waste streams such as fats, oils, and grease (FOG), total suspended solids (TSS) and insoluble BOD. bioprocessH2O provides a complete line of bioDAF units along with ancillary equipment for captial purchase, rental and piloting.
The Dissolved Air Flotation technology (DAF) has proven to be very successful as a pre-treatment step. Nijhuis flotation systems have been developed since the 1970s and our units stand out as …
Dissolved Air Flotation (DAF) VLT Series Systems Dissolved Air Floatation is widely used for separating solids, fats, oil, and grease from a waste stream. In the process, pressurized water is saturated with dissolved air and is discharged into a flotation vessel.
Our Dissolved Air Flotation “DAF” units use a pressurized stream of water to deliver dissolved air to an incoming wastewater treatment stream that contains flocculated waste. When the pressure of the dissolved air and water stream is reduced, the air effervesces out …
• PILOT & RENTAL UNITS We have several DAF pilot plants as well as full scale rental units available. The small (10-100 GPM) pilot units can be installed for 1-2 weeks to test the suitability of a process stream; the full size rental DAF units (500 GPM) can be rented longer term for seasonal processes or emergency situations.
WPL Dissolved Air Flotation (DAF) The WPL Dissolved Air Flotation (DAF) wastewater treatment plant is typically used in a wide range of industrial applications to mitigate the financial impact of trade effluent charges, and maintain environmental compliance.The WPL DAF wastewater treatment system is widely used for the reduction of Chemical Oxygen Demand (COD) present in fats, oils and greases ...
Pre-treatment of trade wastewater by a system based on the Dissolved Air Flotation (DAF) principle is a commonly used best practice option, where grease arrestors or other simple passive pre- treatment devices are inadequate.
Dissolved air flotation (DAF) uses microfine bubbles to float greases, oils and solids to the surface, from where they’re removed. Fluence has been developing and continually improving dissolved air flotation (DAF) systems for decades, and has successfully implemented installations in a variety of …

Dissolved Air Flotation (DAF) is an efficient flotation method for water clarification. The term refers to the method of producing flotation by dissolving air in the …
Applications of Dissolved Air Flotation. DAF units are specifically designed to remove suspended solids which are buoyant in nature (or exhibit near neutral buoyancy) or which have a propensity to float under certain conditions.
What is Dissolved Air Flotation (DAF)? DAF is a mechanical process using ultra-fine air bubbles to separate somewhat neutral or positively buoyant contaminates from water. These contaminates form nuclei on which microscopic air bubbles coalesce.
Dissolved air flotation is designed for the removal of suspended solids or water immiscible liquids from process or wastewater to produce an effluent of high clarity and free of objectionable particles or liquid.
Dissolved air flotation (DAF) has gained widespread usage over the last forty years for the removal of suspended solids (TSS), oils and greases (O&G), and biochemical oxygen demand (BOD) from wastewater and other industrial process streams.
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 …
The Westlake Environmental Dissolved Air Flotation System Is The Best DAF For Your Industrial Water & Wastewater Treatment Needs. Home About Equipment Parts & Service Contact Dissolved ... high performance systems that range from 5 GPM to over 3,000 GPM in a single DAF unit.
Dissolved air flotation (DAF) is a water treatment process that separates liquid from solids, including oil and grease. The process involves microscopic bubbles becoming attached to solid particles causing them to …
Dissolved Air Flotation Equipment Rentals and Pilot Units. Dissolved Air Flotation Equipment Rentals are great when wastewater treatment systems go down for maintenance, when process alterations affect effluent quality, or when capital for purchasing and owning equipment is not available.
What is Dissolved Air Flotation (DAF)? DAF is a mechanical process using ultra-fine air bubbles to separate somewhat neutral or positively buoyant contaminates from water. These contaminates form nuclei on which microscopic air bubbles coalesce.
R5 DAF Overview. The R5 DAF is a pre-engineered, modular, and skid-mounted dissolved air flotation unit with variable tank sizes, flow, and recycle rates.
Dissolved Air Flotation/Dissolved Gas Flotation (DAF/DGF) is a separation technique whereby the adherence of micro gas (air) bubbles to suspended pollutants in a carrier liquid is used to enhance separation efficiency.
The Dissolved Air Flotation Units (DAF) developed by Toro Equipment are designed for the optimum treatment and reduction of the concentration of solids in wastewater. The equipment is manufactured in PRFV, AISI316 steel and PP.
Dissolved air flotation Once in the flotation zone, microscopic air bubbles are injected. The 50 micron bubbles used for flotation are formed by recycling a small stream of clarified water through an air pressurized, packed tower saturator to specially designed nozzles at the DAF cell inlet.
Coupled with the PEWE DAF, this super air saturated water releases uniform 20-30 micron bubbles into the flotation system and effectively floats fine suspended …
DAF or Dissolved Air Flotation is a simple but ingenious concept. Make tiny bubbles by dissolving gas (air typically) into water under pressure according to Henrys Law of gas whereby the pressure applied to gas will dissolve it into liquid (water).
Jul 29, 2013· Siltbuster Limited is the UK's leading supplier of Dissolved Air Flotation (DAF) Systems for a range of industries, applications and flowrates.
Next Generation DAF System. CWT's Gas-Energy Mixing (GEM) System is the next generation of primary wastewater treatment technology. The patented GEM System technology is able to significantly remove higher levels of contaminants from the stream than any other Dissolved Air Flotation (DAF).
Dissolved air flotation [DAF] is a treatment process which removes suspended solids, oil and grease from wastewater. Many applications use the DAF process but it is particularly useful for industrial wastewater treatment as it can reduce COD by up to 90%.
