摘要:

This article is a continuation of “Chlorine‐‐‘Special Agent’ for Disinfecting Water” by Ralph Leidholdt (OpFlow September 1982). In this selection, the author discusses the chemical reactions that occur when chlorine gas, calcium hypochlorite, or sodium hypochlorite is added to water for disinfection purposes. The following chlorine residuals are discussed: hypochlorous acid; hypochlorite ion; monochloramine; dichloramine; and trichloramine. Breakpoint chlorination is also defined and discussed, as well as superchlorination and dechlorination.

摘要:

This month's “Certification Corner” presents problems on the following topics: calculating the solution‐strength by weight of a chemical dissolved in water; calculating filter backwash; identifying organisms frequently associated with tastes and odors in water supplies; determining the reason why backwash rate requirements are greater in summer than in winter; and identifying one compound used as a coagulating chemical in water treatment.

摘要:

This article discusses specific hazards associated with chlorine exposure, proper procedures to follow when working with chlorine, preventive measures to take to avoid chlorine gas injuries, and procedures to follow in treating chlorine gas injuries. Discussion includes safety precautions for use with chlorine gas, calcium hypochlorite, and sodium hypochlorite. Safety features are outlined for rooms in which chlorine containers are being used, and operators are encouraged to become familiar with self‐containing breathing apparatus and how and when to use them.
