Disinfection: TCL Total Chlorine Analyzer

Total chlorine measurement is essential in the control of chlorine in water before its return to the environment in a wide range of industrial applications including desalination. It also provides accurate reporting to the EPA about that control. To meet EPA requirements, the instrument must be reliable for long periods of time and monitor down to 500 ppb. The Rosemount Analytical Total Chlorine Measurement system from Emerson meets and exceeds all requirements while saving money through the use of low-cost reagents.

The Rosemount Analytical TCL from Emerson Process Management, a complete system for measuring total chlorine in water, employs low-cost reagents – white distilled vinegar and potassium iodide – saving significant money and time. The system requires reagent change only every two months – a dramatic reduction over other total chlorine systems. The TCL also uses a low flow rate (less than 6 gal per day), which is a real advantage in areas where drainage is limited and/or water usage is an issue. The complete system incorporates a sample conditioning and measuring system for the continuous determination of total chlorine in water. The conditioning system continuously pumps acetic acid and potassium iodide into the sample. The sensor measures the iodine concentration, and the analyzer displays the total oxidant concentration in ppm as CL2. With no metal wetted parts, it is ideal for seawater and measures samples having alkalinity as great as 300ppm.
