Breaking Down a DAF System
Dissolved Air Flotation is an advanced way of treating wastewater. The system is mainly used in the industrial sector for treating organics, algae, grease, and oil in water. However, DAF has numerous other industrial applications. This video is an illustration of how the DAF system works.
The process involves the separation of contaminant particles suspended on liquids like oil and grease by bringing them to the surface. The particles are then removed physically. The wastewater is first treated, and chemicals like flocculants and coagulants are added. There are three types of DAF, and although they work on the same system, they have minor differences.
The DAF process starts at the flotation tank, which is separated into two sections. The first section is where flocculants are introduced to trap the contaminant particles. It is also known as the reaction section. The second section is the separation zone, where bubbles are introduced. The bubbles should be small to create agglomerates.
The formation of bubbles involves dissolving air in a saturator while under pressure. The bubbles contact the contaminants through adhesion and absorption and then move to the separation sector. This zone facilitates the rising of the bubbles to the tank’s surface so that the thick layer of dirt can be removed. The treated water is then removed from the bottom. The water may get further treatment as needed.
DAF treats wastewater and raw water with oil, grease, algae particles, and other solids. It is very useful in places where water does not settle by sedimentation.
