WebA new method of chlorination called Pulse-Chlorination® was developed by KEMA in 1998. Pulse-Chlorination is based on the principle that mussels and clams, in general have a recovery period before full opening and start filtering after exposure to a chlorination period. The chlorination Web14 seconds. More recent studies on flow C-H chlorination focused on the use of Cl 2 gas in situ generated by photolysis sulfuryl chloride[10] or acid treatment of NaOCl.[11,12] We thought that if rationally designed scalable photoflow setups are available, flow C-H chlorination using chlorine gas would be able to focus on production.
WebContinuous chlorination using an automatic chemical feed pump can effectively remove medium to high levels of hydrogen sulfide (Fig. 4). Chlorine quickly oxidizes hydrogen sulfide into a tasteless, odorless form. Continuous chlorination also effec-tively removes iron and manganese that can occur in association with hydrogen sulfide.
