Dissolved Air Flotation

DAF is a fast and highly efficient method for removing turbidity, color, suspended solids and other contaminants from water using air bubbles. These specially created air bubbles are first mixed with wastewater, attach themselves to solids present and then separate them by flotation

Dissolved air flotation (DAF) is a conventional tech-nology that plays an important role in drinking water and wastewater tertiary treatment. During the DAF process, compressed air is introduced into a recycle stream, is dis-solved, and subsequently generates 10100μm bubbles when released through a dispersion header into a DAF
