Hi ,

You should ask the person /company in charge of the treatment of the cooling water in your facility , he knows the quality of your make up water .

Hope this helps a bit.

Hi ,

To me your water (all) is good quality water !  Utility water should be used .

 

Hope this helps

Looks like chlorides are high in your utility  water. What is the chloride and bicarbonte of utility water? Chlorides are detrimental to SS and bicarbonates will form scalle. Calculate Langlier Index and Stability Index (LI) and (SI). Both  will tell about the nature of water (scale forming or corrosive).  You have to action accordingly..

hi ,

I agree with P.K Rao in general , still needto  investigate with the company in charge of the treatment .

Yes, we used utility water but cooler water spray nozzles frequently chocking due to deposition of salt particles causes tripping of compressor at after cooler high temperature.

Yes Chlorides are 584 mg/L and Sulfates are 380 mg/L in Utility water.

I want to share some pics of salt deposited in water spray nozzles but I don't know how to paste pics here.
