Application Guide: Dissolved Air Flotation Optimization Hach

In industrial processing plants, a Dissolved Air Flotation (DAF) is often used to reduce loadings and clarify wastewater. Tiny air bubbles are released into the tank causing small particulates to float to the top where they are skimmed off. To remove larger suspended solids, coagulant is dosed into the feed water—this helps to speed up ...

Installation, Operation Maintenance Manual

A DAF (Dissolved Air Flotation) system creates microscopic air bubbles that are attached to incoming wastewater particles in order to float them. Once floated, they are separated from the wastewater and skimmed from the top and into the float scum chamber. The treated wastewater then exits from near the bottom of the DAF.
