The term describes a chlorination setup that dissolves chlorine gas in a small amount of water (an auxiliary water supply) to form a chlorine solution, which is then injected into the sewage. This approach is known as a solution feed gas chlorinator because the dosing is delivered as a chlorine-containing solution rather than as pure gas or a different chemical form. It differs from simple gas chlorinators that inject chlorine gas directly into water without forming a defined solution, hypochlorinators that dose liquid hypochlorite, and electrolytic chlorinators that generate chlorine on-site from salt. By creating and dosing a chlorine solution, this method can achieve more consistent mixing and residual control in the sewer.
