2016-2-1However, in specific flotation processes e.g. produced water treatment, air is not preferred due to the presence of oxygen in the air that could lead to possible metal precipitation and explosion. Methane is generally used in produced water flotation systems due its availability and compatibility with the influent aqueous solution.Discover More
DAF system may be designed for pressurization and air dissolution of the total flow or, more commonly, the incoming effluent enters the flotation vessel where it comes into contact with a portion of recycled, treated effluent sometimes termed whitewater. The percentage of the total effluent flow into which air is dissolved under pressure and subsequently recycled will be determined by ...Discover More
Dissolved air flotation DAF is a clarification process that utilizes air to remove suspended matter from the surface of treated water. DAF works by dissolving air under pressure and then releasing millions of tiny air bubbles into the water at atmospheric pressure. This process allows the dissolved air bubbles to adhere to a suspended matter ...Discover More
In accordance with Henrys Law, more air is dissolved into a given volume of water at increased pressures. A 65 psi system requires less recycled water and produces smaller air bubbles than those operated at lower pressures. Recycled water serves to transport dissolved air to the flotation unit.Discover More
2020-7-20Filtration is used in addition to regular coagulation and sedimentation for removal of solids from surface water or wastewater. This prepares the water for use as potable, boiler, or cooling make-up. Wastewater filtration helps users meet more stringent effluent discharge permit requirements.Discover More
2017-1-23Many water treatment plants use a combination of coagulation, sedimentation, filtration and disinfection to provide clean, safe drinking water to the public. Worldwide, a combination of coagulation, sedimentation and filtration is the most widely applied water treatment technology, and has been used since the early 20th century.Discover More
2020-7-19Sedimentation is one of several methods for application prior to filtration other options include dissolved air flotation and some methods of filtration. Generically, such solids-liquid separation processes are sometimes referred to as clarification processes. There is a variety of methods for applying sedimentation and include horizontal flow, radial flow, inclined plate,Discover More
Everyone is familiar with the water cut statistics three to seven barrels of produced water emerge from the ground per barrel of oil. This oft-cited statistic is useful to appreciate the scale of the volumes of water produced in the Permian Basin. However, it does not tell the whole story.Discover More
Air flotation is simply the production of microscopic air bubbles, which enhance the natural tendency of some materials to float by carrying wastewater contaminants to the surface of the tank for removal by mechanical skimming. We offer proven innovative designs for combining the raw wastewater with the formed air bubbles or recycle stream.Discover More
2019-9-30Dissolved air flotation Last updated September 30, 2019. 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.Discover More

1983-3-22A majority of particles in the water is collected by flocs in the water and floated to the water surface by air bubble action. The floating sludge is removed by a spiral scoop carried by the carriage. The water is then passed through the bottom filter which removes the remaining flocs completing the clarification of the water for discharge.Discover More
