Dissolved Air Flotation (DAF) is a separation technique whereby the adherence of micro air bubbles to suspended pollutants in water is used to enhance separation efficiency. DAF is applied when the density of the suspended pollutants is close to that of the water so that gravity separation becomes very difficult.
The Pipe Flocculator consists of a calculated length of pipe which is expanded in diameter along its length in order to facilitate the slower ortho-kinetic floc building up. The pipe is divided into certain lengths that are connected by 180° elbows.
