Environmech Sdn. Bhd. since 2012: Dissolved Air Flotation (DAF), Malaysia Supplier

Dissolved Air Flotation (DAF) has been known and applied widely as one of the most effective and economical ways to remove suspended solids (SS), fats, oils and grease (FOG), phosphorus (P) from industrial wastewaters by the generation of microbubbles.

Our DAF is an innovation combined with traditional dissolved air flotation design theory and modern technology after years of research and application.DAF is based on a physical/chemical process. Wastewater is dosed with treatment chemicals upstream of the DAF inlet to form flocs.

When those flocs enter the DAF chamber, massive microbubbles attach to the flocs and bring them floating to the top. The floating solids are harvested by DAF’s top skimmer. After the separation process, clean effluent will be collected and discharged.

The generation of microbubbles is through the air saturation vessel and air diffuser plates. A portion of the DAF effluent is recycled to the air saturation vessel to mix with air by venturi jet under high pressure, and form air dissolved water (white water) . When the air-dissolved water flows to the air diffuser plates, the sharp reduction of the pressure will make the microbubbles release from the air-dissolved water, and form massive microbubbles.

DAF-Standard DAF SYSTEM

Dissolved Air Flotation (DAF) is a water treatment process that removes suspended solids, oil, and grease from wastewater by using air bubbles as a flotation agent. The process works by adding small air bubbles to the wastewater, which cause the suspended particles to float to the surface, where they are removed by skimming. The purified water is then drained from the bottom of the DAF tank. DAF is commonly used in industrial wastewater treatment, municipal wastewater treatment, and drinking water treatment.

IDAF/IDAF2-Integrated DAF/DAF2

We have standardised DAF products, which have 5 types in total. The above picture is our IDAF (flat bottom) /IDAF2 (slant bottom) series. It has those main features: 1. Perfect combination of chemical reaction device and DAF unit 2. Compact design for smaller footprint, and easier installation 3.The most cost-effective solution and the best-seller series 4. Design hydraulic loading rate:4-6m3/m2/h

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.
