Optimizing dissolved air flotation design system - SciELO

In dissolved air flotation (DAF), the water saturated with air under pressure (higher than 3 atmospheres) passes through a nozzle whereby the bubbles are formed and reach the flotation chamber, which is at atmospheric pressure. The air becomes supersaturated and precipitates out of solution in the form of tiny bubbles

Dissolved Air Floatation - DAF - United International

Dissolved Air Flotation (DAF) systems are designed to remove suspended solids (TSS), biochemical oxygen demand (BOD5), and oils and greases (O&G) from a wastewater stream. Contaminants are removed through the use of a dissolved air-in-water solution produced by injecting air under pressure into a recycle stream of clarified DAF effluent

Dissolved Air Flotation For Water Clarification: Edzwald

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

Dissolved Air Flotation Applications for DAF Flotation

Dissolved air flotation is a method for separating and removing sus-pended solids from liquid based on changes in the solubility of gas as pressure varies. Air is dissolved under pressure in a clean liquid, usually recycled effluent from the DAF unit, and injected into the raw feed stream. Upon entering the DAF unit, the air pressure is re
