Analytical instruments and overcoming process challenges
Citizens Energy Group had long relied on another manufacturer’s analyzers to monitor total chlorine levels, which were used to estimate bromine concentrations for microbial control. While effective, the units required monthly reagent changes, biannual service visits and frequent part replacements.
Memosens technology: a solution for chilled water systems
The utility team engaged Endress+Hauser and George E. Booth Co. to explore advanced alternatives for chlorine monitoring. Following a productive consultation with George E. Booth Co., a new digital total chlorine sensor Memosens CCS53E was installed.
What is total chlorine?
Total chlorine refers to the combined concentration of all chlorine-based disinfectants present in water, including:
Free chlorine – the active form that disinfects (e.g., hypochlorous acid and hypochlorite ion)
Combined chlorine – chlorine that has reacted with organic or inorganic compounds (e.g., chloramines)
Total chlorine = free chlorine + combined chlorine
What is bromine?
Bromine is a chemical disinfectant used in industrial water systems, especially where high temperatures or organic loads are present. It’s effective at removing bacteria and viruses and is often estimated by measuring total chlorine when bromine is generated from bromide salts.
What are the advantages of using chilled water systems?
Chilled water systems offer efficient, centralized cooling for large buildings and industrial facilities. Instead of using individual air conditioning units, these systems circulate chilled water through a network of pipes to absorb heat and maintain temperature control.
