The well water is high in iron content that must be removed to avoid staining of clothes and plumbing fixtures, as well as to improve the taste. Well Raw Water Piping from Well Aeration Aeration is a process that mixes air and water for oxidation. The process of oxidizing brings the iron in the well water from a dissolved state into a state of suspended matter. Suspended iron is easier and more cost effective to remove. Aeration also removes any dissolved gases which may be present in the groundwater.
Chlorine performs two duties in the treatment process.
The main purpose of chlorine addition is for disinfection. Disinfection of the drinking water neutralizes any microorganisms which could be present in the water. Also, the addition of chlorine assists the aeration process in oxidizing the iron from a dissolved to a solid state. This makes it easier to accomplish other steps in the treatment process and also prevents corrosion from occurring in the treatment plant and the distribution system. After the particles have settled out, they can be removed more easily.
