The air micro-bubbles are used in dissolved air flotation systems (DAF), in which air is dissolved in clean water recycled from the flotation tank. The clean water is injected in a pressurized saturation vessel, also named saturator, to dissolve air and then be released into the flotation tank through a needle valve. Then, producing air micro ...

Dissolved Air Flotation (DAF) has been known as one of the most effective and robust ways to remove suspended solids (TSS), biochemical oxygen demand (BOD 5), fats, oils and grease (FOG), phosphorus (P) or nutrients from industrial wastewaters.In response to variations in industrial activity, variations in wastewater and water streams and the ever …
What is it? Dissolved Air Flotation, or DAF, is a method of wastewater treatment in which dissolved air is released from solution in a flotation tank. The resulting bubbles collect around any materials suspended in the wastewater, floating those materials to the surface where they can be removed by a skimming device.
Dissolved air flotation (DAF) units have been a traditional thickening device for decades. In recent years, devices such as gravity belt thickeners and rotary drum thickeners have gained popularity as alternative process choices. These units are typically smaller in foot print, have fewer components, and consume less power than DAFs.

The lower edges of the tabletops are beveled to allow for precise fit with the frame. Air plenums are made of hard plastic and sealed with silicon gel.
DAF system is widely used in industrial wastewater reuse, pretreatment system before membrane treatment, reclaimed water reuse, MBBR biological film process. 1.The bubble size is less than 10um, Dissolved gas efficiency is over 95%. 2.Land-occupying province,the solid suspended matter content in effluent can be less than 20 mg/L.
In lamella flotation units based on separation of air bubbles in thin liquid layers, treated wastewater containing a water-air mixture is passed between the inclined plates, and the air bubbles float vertically up to the surface of the upper plate (Fig. 1 b).Download : Download high-res image (351KB) Download : Download full-size image …
LOW AIR CONSUMPTION: The ADT consumes less than 1 SCFM/500 liters (132 gallons) of ADT capacity. MAXIMIZED FLOTATION: When the ADT is matched with a properly sized globe valve for pressure release, the ADT will produce a 10-70 micron air bubble which is well suited for dissolved air flotation. INSTALLATION VERSATILITY: The ADT

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. DAF are incorporated when the sludge is less dense than water, or is …
DAF is used to separate solids from a liquid through the use of very fine air bubbles. These bubbles stick to the suspended matter — whether it's algae, oil, or another contaminant — temporarily reducing its density. The buoyant bubbles cause the particulates to rise to the surface. Source or untreated water that contains light, buoyant ...
