Coarse Separation
Clarification & Sedimentation consists of removing all kind of particles, sediments, oil, natural organic matter and color from the water to make it clear.
A clarification step is the first part of conventional treatment for waste and surface water treatment.
Sedimentation is the separation from water, by gravitational settling, of suspended particles that are heavier than water. It is one of the most widely used unit operations in water and wastewater treatment.
The particle separation processes in sedimentation include the following: Coagulation, sedimentation, and flotation. Other technologies for particle removal by processes such as filtration and membrane technologies and complex systems will be described in another activity.
Particle separation is a key process in water and wastewater treatment, with a vital role in meeting water quality standards around the world, and encompassing a very wide range of particulates in widely varying contexts.
