usters Water offers a complete line of dissolved air flotation (DAF) systems. Ideally suited for liquid solid separation in municipalities and many industries, including separation of free oils and grease. The DAF units are designed for effective removal of total suspended solids (TSS), biochemical oxygen demand (BOD) and fats, oils and grease (FOG).

Nov 16, 20190183;32;The common parameters for dissolved air flotation process are tabulated in Table 7.1. Gravity thickeners are essentially circular primary settling tanks with or without mechanical thickening devices. The dilute sludge is fed into the settling tank where solids are allowed to settle over a few days.

Installation, Operation Maintenance Manual

The RAD system is used to create water that is saturated with dissolved air and introduces this air/water mixture into the DAF flotation/separation chamber at the influent point. Once in the separation chamber, the dissolved air begins to come out of solution and create small air bubbles that attach to the particles (oil droplets, solids, etc.)

Sludge Thickening Tank Thickener Design

How Dissolved Air Flotation Sludge Thickening Works. Sludge thickening tanks are typically designed in three different ways, with each design using a different process to thicken the sludge. The three methods that are used to thicken sludge include gravity thickening, centrifugation and dissolved air flotation.

Dissolved air flotation

Dissolved air flotation

Dissolved air flotation (DAF) is a water treatment process that clarifies wastewaters (or other waters) by the removal of suspended matter such as oil or solids. The removal is achieved by dissolving air in the water or wastewater under pressure and then releasing the air at atmospheric pressure in a flotation tank basin. The released air forms

discussed after a short look at the most important basic elements of dissolved air flotation. For dissolved air flotation the waste water or a split flow of the clarified water, with pressure being applied in the range from 4 to 6 bar, is saturated with air and then passed over the flash valves into the flotation tank.

Dissolved Air Flotation (DAF) Systems

Dissolved Air Flotation (DAF) systems are designed to remove suspended solids (TSS), biochemical oxygen demand (BOD 5), and oils and greases (OG) 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.
