PRECHLORINATION Meaning and
Definition
-
Prechlorination is a water treatment process wherein chlorine is added to the water prior to any other disinfection or treatment procedures. It is an initial step in the process of purifying water supplies to kill and control the growth of microorganisms, algae, and other harmful substances.
The word "prechlorination" is derived from the prefix "pre-", meaning before, and "chlorination", which refers to the process of adding chlorine. This technique involves introducing chlorine-based chemicals, such as chlorine gas or sodium hypochlorite, into the water supply at the source, often at the water treatment plant.
Prechlorination serves several purposes. Firstly, it rapidly eliminates any existing bacteria, viruses, and parasites in the raw water. Secondly, it neutralizes or reduces unwanted odors and tastes caused by the presence of certain organic compounds. Thirdly, prechlorination aids in controlling the growth of nuisance organisms such as algae and their associated byproducts, which can affect water quality and make it visually unappealing.
Furthermore, prechlorination can help prevent the formation of harmful disinfection byproducts (DBPs), such as trihalomethanes (THMs), by oxidizing the organic precursors present in the water. This process also protects downstream treatment equipment from fouling and enhances the efficiency of subsequent disinfection methods, such as chloramination or ultraviolet (UV) irradiation.
In summary, prechlorination is the initial step of adding chlorine-based chemicals to water sources as a means of disinfection, algae control, odor and taste elimination, precursor oxidation, and overall improvement of water quality.

Etymology of PRECHLORINATION
The word "prechlorination" consists of two roots: "pre-" and "chlorination".
1. "Pre-" is a prefix derived from the Latin word "prae", meaning "before" or "in advance". It is used to indicate that something occurs before the main action or event.
2. "Chlorination" comes from the term "chlorine", which is a chemical element with the symbol "Cl". Chlorine is a highly reactive and strong oxidizing agent commonly used in disinfection processes. The word "chlorination" refers to the act of treating water or other substances with chlorine to kill bacteria, viruses, and other pathogens or to disinfect and purify them.
When combined, "prechlorination" refers to the application of chlorine or chlorination treatment done in advance or before the primary treatment or process.
