What process is used to remove large particles from water in treatment?

Coagulation and flocculation is the correct process used to remove large particles from water during treatment. This method involves the addition of chemicals known as coagulants, which help to destabilize the particles suspended in the water. As these particles clump together, they form larger aggregates called flocs. The flocculation phase involves gentle mixing to encourage the formation of these larger particles, which can then be easily removed from the water through subsequent processes like sedimentation or filtration.

While filtration may also be used to separate particles from water, it is primarily employed for smaller particles after the coagulation and flocculation process has been applied. Distillation involves heating water to create steam and then condensing it back to liquid, which is not effective at removing large particles. Reverse osmosis is a membrane process that is effective in removing dissolved solids and various contaminants, but it is not designed specifically for large particulate matter. Therefore, coagulation and flocculation play a crucial role in the initial stages of water treatment for effectively removing larger particles.
