The water is than disinfected‚ usually by means of chlorination. Removal of dissolved solids Microrganisms are not only a threat to water; they can also be an advantage when it comes to water purification processes. They can convert harmful contaminants to harmless substances. This biological purification

CLEAN DRINKING WATER Our primary needs are food‚ water and shelter; but water is the most important need of every person. Without water‚ we cannot survive. Even for one day‚ we cannot live without water. If we have safe and clean water for drinking ‚ we’ll live healthy and prosper. The clean water we drink and which is germless is called potable water. The water we drink in our homes‚ is supplied by the municipal community. We think that it is safe and germs free but in reality it is not fully
