Monoclor Chloramine Residual Management System Manages Residual For Problematic 5.5 Million Gallon Tank

Eastern Municipal Water District (EMWD) serves about 142,000 customers in Riverside County, CA. The EMWD service area is one of the largest for any water district in arid southern California. On the drinking water side, EMWD manages two water treatment plants and over 15 reservoirs. With 70% of the district’s water coming from the Metropolitan Water District with chloramine disinfection, EMWD has become reliant on chloramine disinfection to manage long transmission lines and longer detention times.

Disinfection: TCL Total Chlorine Analyzer 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 Total Chlorine Measurement system from Emerson meets and exceeds all requirements while saving money through the use of low-cost reagents.

ABOUT DRINKING WATER DISINFECTION

WATER DISINFECTION

Water disinfection is the process of removing unwanted chemicals, biological contaminants, suspended solids and gases from contaminated water. It is also the elimination, deactivation or killing of pathogenic microorganisms.

Methods used include physical processes such as filtration, sedimentation, and distillation, biological processes such as slow sand filters or activated sludge, chemical processes such as flocculation and chlorination and the use of electromagnetic radiation such as ultraviolet light.

Ozonators produce small quantities of ozone which is a strong oxidizing agent that kills pathogens over a short period of time.
