Sewage Separation Technology Equipment Dissolved Air Flotation in Dyeing Wastewater Treatment System

The most prominent problem of Dyeing wastewater is high concentration of organic pollutant. In dyeing wastewater treatment process, solid-liquid separation and its equipment are one of the key projects. DAF dissolved air flotation is one of the most effective methods whose specific gravity is close to 1.0 from water.

Principle

Working principle of DAF dissolved air flotation unit:

The feed water of dyeing wasterwater to DAF dissolved air flotation tank is often (but not always) dosed with a coagulant (such as ferric chloride or aluminum sulfate) to coagulate the colloidal particles and/or flocculants to conglomerate the particles into bigger clusters.

A portion of clarified effluent water leaving the DAF dissolved air flotation tank is pumped into a small pressure vessel (called air drum or saturator) into which compressed air is also introduced. This process saturates pressurized effluent water with air under pressure (2.5~4kg/cm²).

1. Micro bubble generation

2. Sedimentation technology

3. Counter current mechanism

4. Scum circulation and flocculation technology

5. Hypo-surface capture technology

6. Laminar flow in separation zone technology
