Our CDA Series Dissolved Air Flotation (DAF) system is a wastewater treatment technology used for the removal of suspended solids, oils, and other contaminants from industrial or municipal wastewater. The DAF system uses air bubbles to separate the contaminants from the water.
The DAF system typically consists of a flotation tank, a skimmer or scraper mechanism, an air injection system, and a solids collection system. The flotation tank is where the water to be treated enters the system, and the air injection system introduces air bubbles into the tank. The air bubbles attach to the suspended solids and cause them to float to the surface of the tank, where they are removed by the skimmer or scraper mechanism.
The solids collection system collects the removed solids and sends them to a sludge holding tank for further treatment. The treated water is then discharged or sent for further treatment.
DAF systems are commonly used in industries such as food and beverage, dairy, paper and pulp, chemical processing, and oil and gas, among others. They are also used in municipal wastewater treatment plants for primary and secondary treatment, as well as tertiary treatment to remove nutrients such as phosphorus and nitrogen. DAF systems are efficient, cost-effective, and environmentally friendly, making them a popular choice for wastewater treatment.
