Us10093554b2 Multibubble Injection Type Dissolved Air

Disclosed herein is a multibubble injection type DAF Dissolved Air Flotation water treatment apparatus which supplies fine bubbles injected through injection of saturated water to a lower area of a separation zone as well as a lower area of a contact zone of a flotation basin, thereby improving removal efficiency of flocs.

Daf Micro Bubble Generator Air Dissolving Daf Corp

The DAF AMT micro bubble generator air dissolving mixing tube is an essential complement to a dissolved air flotation clarifier. The AMT produces billions of microscopic 20 to 50 microns, uniformly sized air bubbles that attach themselves to the waste particles making them strongly buoyant.

Optimizing Dissolved Air Flotation Design System

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 Flotation Daf Lian Tadbir

Dissolved Air Flotation DAF systems are designed to remove suspended solids TSS, biochemical oxygen demand BOD5, and oils and greases OampG 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.
