Chlorine Measurement In Wastewater And Regulated Discharge Requirements
8/8/2014
Homes, industry, schools, and businesses all generate sanitary waste, or sewage. Sewage treatment is a multistage process that cleans up wastewater before discharge or reuse. In the final step of the treatment, disinfectants are added to kill disease-causing organisms. Common disinfectants are chlorine gas and sodium hypochlorite. Chlorine dosage levels are designed to leave almost no residual in the wastewater after treatment

Application Note: Chlorine Measurement By Amperometric Sensor
6/2/2009
Chlorine in aqueous solutions is used for a number of purposes such as disinfection, taste and odor control, bleaching, and as a powerful oxidizing agent in various manufacturing processes. Chlorine is a costly chemical and requires large amounts of energy to produce. About 3000 KWH are required to produce a ton of chlorine from brine, and the delivered cost ranges from $160 to $300 per ton. As energy becomes more expensive, so inevitably will chlorine.

Case Study: Newport News Uses Emerson Ozone Instrumentation For Safe, Effective Disinfection
5/22/2006
Maintaining the quality of the water supply is the top priority for municipal drinking water treatment plants across the country. Water plants use several treatment processes to ensure water quality and safety, and these treatment steps include disinfection. Traditionally, chlorine is used in both primary and secondary disinfection treatments and has been used since 1908. Some water plants are moving to ozone for primary disinfection. One water utility that is taking this direction is Newport News Waterworks.
