Dissolved Air Flotation Unit In South Africa

Dissolved air flotation has been used in South Africa for more than 25 years in the field of water and wastewater treatment, with practically all the development and verification done locally. This substantial body of knowledge and experience was recently condensed into a document titled A South African Design Guide for Dissolved Air Flotation

3D TRASAR™ Technology for Dissolved Air Flotation (DAF) is the next generation of DAF performance management. Its advanced control algorithms determine the appropriate chemical dosage to your system in real time. It continuously detects critical systems changes such as Total Suspended Solids (TSS), pH and process flow and provides remote

Pressurized flow is released in a conical pattern inside the flotation unit, producing thorough mixing with minimal turbulence. Loss of dissolved air through external piping or distribution systems is prevented. The air-water-solids mixture is uniformly distributed across the flotation tank by action of the inlet diffusion chamber

Dissolved air flotation filtration is a water treatment process that clarifies polluted waters by removing suspended pollutants such as oils and various solids. The waste removal is achieved by dissolving air in the water or wastewater under pressure and then releasing the air at atmospheric pressure into a flotation tank or basin

Relief of dissolved air into the DAF unit should be through an appropriate self flushing valve with broad seat clearance. Manual valves (i.e. ball valves) must not be used in an attempt to maintain constant dissolved air feed to the DAF unit, as they are likely to partially block and result in turbulent large air bubbles. This decreases the performance and reliability of the DAF unit
