Water Quality Standards For Heat Exchangers - Vasai

I want to like to obtain information pertaining to the maximum limit of calcium, magnesium, sodium salts in industrial water used for the purpose of cooling heat exchangers. Our plant is based at Vasai, coastal area. Relevant standards may kindly be mentioned. We would like to ascertain if our current processes are matching required quality demands & adjust as needed if modifications are needed.

Dear Mr.Malshe,

I am a Water Management Consultant with close to 40 years of experience with a lot of time spent in Industrial Water Treatment.

Is your system a twin circuit system? i.e the primary circuit with the heat exchanger and a secondary circuit comprising a circulatory cooling system to cool the heat exchanger with a cooling tower in the circuit.

If the answer is yes, the primary circuit with the heat exchanger must have demineralised water in it. The secondary circuit with a cooling tower must have at least soft water with a total hardness between 5 to 10 mg/lit as CaCo3 and with a comprehensive chemical treatment programme to prevent corrosion and fouling.

The total dissolved solids in the secondary system is critical as it can have a major effect on the cycles of concentration in the system which is critical.
If you send me a test report of the treated water used in the secondary circuit,I can give you suggestions.

Regards
