Get Price- Can CFD modeling be used in water treatment flocculation?
- The CFD approach can be applied to study the hydrodynamic behavior of the full scale flocculation system, and optimize the operational conditions at the limit or beyond design capacity. A review of CFD modeling in water treatment flocculation processes is presented by Bridgeman et al. .
- What is coagulation flocculation?
- The coagulation flocculation is considered the most important process in water surface treatment. Coagulation allows by the injection and the scattering of chemical (coagulants) during relatively intense mixing to destabilize naturally occurring particles and macromolecules and/or to precipitate additional particles (Mackenzie and Cornwell 1991).
- How does flocculation work?
- Introduction Flocculation is a crucial unit operation in drinking water and wastewater treatment. By using flocculation chemicals, the smaller destabilized particles are agglomerated into larger ones, known as flocs. Then, the flocs are separated by the solid-liquid separation process as filtration or sedimentation to decrease turbidity and color.
- Are settled turbidity removals dependent on flocculation conditions?
- Settled turbidity removals were dependent on the applied mixing conditions. Filtered turbidity was found to be independent of the investigated flocculation conditions, which calls into question the true value of mixing conditions with substantial implications on facility design, operation, and regulation.
