How does a water treatment plant work?
Most of the water treatment plants make use of a sand filter. The sand filter is low-tech but is a very efficient way of carrying out water purification. Once the water reaches the filtration phase, it is made to pass through differing coarseness of sand. Particles keep on getting trapped as the coarseness of the sand filter decreases.

How does a drinking water treatment plant work?
Water treatment plants can use a process called ultrafiltration in addition to or instead of traditional filtration. During ultrafiltration, the water goes through a filter membrane with very small pores. This filter only lets through water and other small molecules (such as salts and tiny, charged molecules).
