4 Essential Purification Steps Water Treatment Plants Follow, New Haven, Connecticut

Ground and surface water can contain a number of harmful contaminants that can cause serious water-borne illnesses among adults and children alike. To combat these dangerous toxins, water gets treated following strict regulations, ensuring the water supplied by the Regional Water Authority is safe for consumption. The Regional Water Authority in New Haven explains the process some water treatment plants follow to provide clean drinking water for nearby communities.

4 Steps At Water Treatment Plants

1. Coagulation

Water treatment plants begin the purification process by cleansing water of visible dirt and debris through a method called coagulation. This is done by adding positively charged compounds which react with water pollutants to form insoluble particles known as flocs.

2. Sedimentation

3. Filtration

Clear water left behind after dirt removal is further purified by passing through several natural filters, including charcoal, gravel, and sand. As it moves through a variety of pore sizes in the water filtration process, the supply loses much of its microbial content like viruses and bacteria.

4. Disinfection

Also called chlorination, the final step entails adding chemicals like chlorine to disinfect the filtered water. By doing so, water treatment plants ensure that your supply is completely cleansed of any parasites and germs left behind during water filtration.
