Dissolved Air Flotation System, commonly known as DAF, is a highly effective and efficient treatment process used in wastewater treatment plants. It is a physical-chemical separation process that removes suspended solids, fats, oils, and greases from wastewater by using air bubbles. The DAF process is based on the principle that air dissolves better in water under pressure, and the dissolved air is released under atmospheric pressure in the flotation tank. The released air forms small bubbles that attach to the suspended solids and float them to the surface, where they are removed by skimming.
The DAF system is widely used in the water treatment industry due to its high removal efficiency and low maintenance cost. It is used for various applications, including food and beverage processing, chemical and petrochemical processing, pulp and paper processing, and municipal wastewater treatment. The DAF system can effectively remove suspended solids, fats, oils, and greases, which are harmful to the environment and human health.
The DAF system has several advantages over other wastewater treatment processes. It has a smaller footprint and requires less space than conventional sedimentation tanks. It can treat a wide range of wastewater flows and concentrations, making it suitable for various industrial applications. The DAF system can also handle wastewater with high oil and grease content, which is difficult to treat with conventional methods. Additionally, the DAF system produces less sludge, reducing the cost of sludge disposal.
The DAF system can be customized to meet specific industry requirements. It can be designed for high flow rates and can be integrated with other treatment processes, such as biological treatment or chemical treatment. The DAF system can also be designed for different water temperatures and pH levels. The DAF system is a reliable and efficient wastewater treatment process that meets strict environmental regulations and reduces the impact of industrial wastewater on the environment.
