The Water Treatment Process
The water treatment process begins with pump stations drawing in raw water from a variety of lakes, streams, and underground aquifers.
- The raw water is transported to a water treatment center where the larger sediment and particles are removed with the use of chemicals known as coagulants. These coagulants act like magnets to pull in these particles and caused them to clot together (flocculation).
- Depending on the water treatment center, the flocculation will either be drawn to the bottom of the tank or air is pumped in to force flocculation to rise to the top of the tank. This part of the process will remove the majority of the sediment from the water.
- Filtration is required to remove any residual particles from the water. The filtration is layers of activated carbon, sand, and gravel which traps and holds any particles left behind by the coagulants. Other layers of filtration media such as activate alumina will remove specific toxins such as fluoride and arsenic.
- The last step is to disinfect the water of tiny microorganisms which can cause a person to become ill. Chlorine and ozone are the most popular additives to scrub and clean the water from any bacteria or viruses.
The water treatment process is complete and now it’s ready to drink!
