Water Testing: Residual Chlorine in Wastewater

Mar 28 2006

Chlorine has a long history of being used as a disinfectant, but QCL Scientific say it has certain health and safety limitations. Chlorine is used as a disinfectant because it destroys target organisms by oxidising cellular material. Disinfection of municipal wastewater is necessary to preserve watershed quality.

One disadvantage of using Chlorine even at low concentrations is the toxicity to aquatic life as oxidation of certain types of organic matter in wastewater creates more hazardous compounds. Therefore, proper measurement of residual chlorine levels requires precise, accurate products such as the Orion 4-star pH/ISE meter and Orion Solid-State Chlorine electrode.

Just some of the unique features available on the Orion 4-Star meter are downloadable internet updates, five point calibrations for direct ion measurement and a special storage mode that allows you to store and password-protect up to 10 methods. On site measurements with Orion meters allow faster readings with an easy to read LCD display. Since treated wastewater can be for drinking and recreational purposes, the proper treatment and measurement of residual levels must comply with government regulations.
