own as a water-treatment method in which water is filtered through a screen to eliminate chemical contaminants and microorganisms is known as reverse filtration. chlorination. distillation. micron filtration.
I believe the water treatment stated above is micron filtration. Micron filtration is a water treatment method where water is filtered through screens that have microscopic holes. The holes are measured in microns and the smaller the hole the more contaminants can be removed.
Micron filtration is a process of water clarification in which waste or impure water is passed through a set of sieve which can be of any pore size depending upon the impurity type i.e the size of contaminants or micro organism
However in reverse filtration water is force to passed through a semipermeable membrane on application of pumping force. Distillation is a physical process of cleaning in which mixture is separated based on difference in boiling points and chlorination is addition of chlorine or its compounds.
