The efficiency of coagulation and flocculation will greatly determine the success of your entire treatment process.
Flocculation is the accumulation of destabilized particles into microfloc and later into bulky floccules.
During this process, slow stirring and particle contact aid the formation of the floc particles.30 Jul 2012
What is the purpose of flocculation?
Flocculation: A process wherein colloids come out of suspension in the form of floc, either spontaneously or due to the addition of a clarifying agent. It is used in applications like water purification, sewage treatment, cheese production and brewing, for example.
Why is coagulation and flocculation important?
Coagulation-Flocculation. Coagulation-flocculation is a chemical water treatment technique typically applied prior to sedimentation and filtration (e.g. rapid sand filtration) to enhance the ability of a treatment process to remove particles. Dissolved and suspended particles are present in most of natural waters.24 May 2019
What is flocculation and why is it important for clean water?
In conventional coagulation-flocculation-sedimentation, a coagulant is added to the source water to create an attraction among the suspended particles. The mixture is slowly stirred to induce particles to clump together into “flocs.” The water is then moved into a quiet sedimentation basin to settle out the solids.
What is the purpose of flocculation in water treatment?
Drinking Water Treatment – Flocculation. Now that the particles have a neutral charge and can stick together. The water flows into a tank with paddles that provide slow mixing and bring the small particles together to form larger particles called flocs. Mixing is done quite slowly and gently in the flocculation step.
