Liquid ring compressors, service water and seal water shall be treated to control_________.

• A. All of the above
• B. waterborne pathogens
• C. chlorine
• D. hyper chlorination

Answer: (A)

Water quality in service and seal water is critical for liquid ring compressors because these waters come into direct contact with moving parts and can contaminate the gas stream if they harbor microbes or have improper disinfectant levels. Treating the water aims to keep it free of waterborne pathogens, ensure chlorine levels are managed so disinfection is effective but not excessive, and control hyperchlorination to avoid damage to equipment and residuals that could affect gas purity. When all these aspects are addressed by treatment protocols, you reduce microbial risk, protect the integrity of the medical gas system, and maintain safe, clean operation—so selecting all of the above reflects the full scope of necessary water treatment.
