Sedimentation process in water treatment

Posted on by

Sedimentation is the process of allowing the particles present in water in suspension to get ettle out of the suspension with the help of the effect of gravity. The particles that get settle down in the bottom becomes sediment ad it is known as sludge. When a thick layer of this sludge keeps on settling down then it is known as consolidation. When mechanical means start assisting this consolidated sludge or sentiment then this is known as thickening. Grease trap denver are used for filtration and for the treatment of septic tanks, denver septic tank services is available on denver drain cleaning companies.

During the water treatment process, the untreated water is passed through the sedimentation process to reduce the number of particles in suspension before the process of coagulation so that the number of coagulation chemicals required for the coagulation process can be reduced or after the coagulation process or flocculation. When sedimentation is done after the process of coagulation, the main aim is to reduce the concentration of solids in suspension so that the subsequent filtration can function at its best.

The sedimentation process is one among the many methods which are used before the filtration process: the other process includes dissolved air flotation and some other methods of filtration. Generally, the process which separates the solid particles from the liquid matter is known as the clarification process.

There are various methods through which we can apply the sedimentation process and these various processes include: radial flow, horizontal flow, ballasted floc, inclined plate, and floc blanket sedimentation.

When the concentration of solid particles present in water is extremely low, approximately less than 1% v/v, the particles have negligible Impact on each other after getting settled down at the bottom. As the concentration of the particles starts increasing and when it becomes greater than 1%, the particles start impacting the adjacent particles i.e., hinder. Furthermore, when the concentration of solid particles gets increased by more than 8% v/v, at the point the suspension is in Completely obstructed governance.

When the concentration of particles is about to touch the mark of 18% v/v, then there is a transition in the appearance in the suspension. When the concentration of particles becomes greater than the 18% v/v, the upper interface should be distinct between suspension and water. When the concentration is less than 18%, then the interface gets diffused, increasingly so with smaller concentrations.
