Which of the following process does not take place in domestic water treatment?

The process that does not take place in domestic water treatment is neutralization. Domestic water treatment involves several processes to make water safe for human consumption. Chlorination is a process that involves adding chlorine to water to kill harmful microorganisms. Flocculation is the process of adding a chemical called a flocculant to water to help clump together small particles and impurities, making it easier to remove them through sedimentation. Sedimentation is a process in which the water is left to settle, allowing heavy particles and impurities to sink to the bottom. Neutralization, on the other hand, is a chemical process that involves the reaction of an acid with a base to form water and a salt. This process is not typically used in domestic water treatment, as the pH of the water is usually adjusted through other means such as adding lime or carbon dioxide.
