Water treatment plant is used to treatment of water like removal of hardness, microorganism, salts and impurities in order to improve the color, odour, taste or properties of the fluid. Water may be treated differently in different communities depending on the quality of the source water that enters the treatment plant. The water that enters the treatment plant is most often either surface water or ground water. Surface water typically requires more treatment and filtration than ground water because lakes, rivers, and streams contain more sediment (sand, clay, silt, and other soil particles), germs, chemicals, and toxins than ground water.
