Which of the following process is used to remove dirt and sand from wastewater?
Which of the following process is used to remove dirt and sand from wastewater?
The correct option is C Sedimentation
Flocculation refers to the process by which fine particulates are caused to clump together into a floc. The floc may then float to the top of the liquid (creaming), settle to the bottom of the liquid (sedimentation), or be readily filtered from the liquid.
Distillation is the action of purifying a liquid by a process of heating and then cooling.
Aeration is the process that allows air and water to penetrate into built-up grass or lawn.
Sedimentation is a process of separating specifically heavier, suspended matter present in a solution. Solid matter settles on the bottom of the vessel and the liquid above it is poured off. Hence, sedimentation is used to remove dirt and sand from wastewater.
