The term "hydrocleaner" encompasses a variety of technologies used in environmental and water treatment, all aimed at removing impurities and contaminants from water sources. One prominent example is the Dissolved Air Flotation (DAF) system, a highly effective process employed in a wide range of applications, from municipal wastewater treatment to industrial effluent cleanup.
Baker Hughes Process Systems, a leading provider of environmental solutions, offers a sophisticated DAF system known for its efficiency and reliability.
Understanding Dissolved Air Flotation (DAF)
DAF utilizes the principle of air flotation to remove suspended solids and other impurities from water. The process involves saturating a pressurized water stream with air, forming tiny air bubbles. When the pressure is released, the dissolved air forms microbubbles that attach to the particles in the water, making them buoyant and allowing them to float to the surface. A skimming mechanism then removes the concentrated solids, leaving a cleaner water stream.
