Technical Minute - Condenser
Corrosion & White Rust
Do you have visible white rust and corrosion on your condenser? If so, why? Did you know when it was occurring or it just happened over time? Most folks don't know that it is happening because they are blindly trusting their water treatment representative. This photo is a prime example of what happens when the tests are ran based on a program and not on results. If the right tests would have been ran, the site would have known this was occurring and changes could have been made to prevent this damage. At Sustainachem, we educate and partner to stop damage before it is visible.
Scale Formation & Leaks
Do you have scale on your coil? In the picture you see scale all over the coil and then a white scale on top in one area. This is an ammonia leak. It is not detectable as it dissolves in the water. The high dollar controller is increasing acid feed and blowdown to control. No one even knew there was a leak. The scale was built up over time but had a simple mass balance been completed and adjustments made to the program, no scale would be visible on this 5 year old condenser coil. Sustainachem focuses on mass balances to know when scale is forming, what type of scale and then adjusts to stop it before it is visible. It doesn't have to look this way.
Scale in Mist Eliminators
Do you have hard scale in your drift eliminators? Have you been told it is just because of evaporation and a design issue? If so, that is not true. The fact is that if mass balances had been ran then your representative would have told you that calcium carbonate was forming and made the right adjustment to stop it. If the treatment levels are correct then the only precipitation that should occur is calcium phosphate which is soft and washes off easily. Hard deposits are due to poor treatment. At Sustainachem we inform our customers when scale is forming and what type. If we see calcium carbonate we adjust, if we see calcium phosphate we also adjust because calcium phosphate forms mud in your basin. It isn't from the road, it is from overfeeding cooling water products. Don't turn up the pump, figure out he issue and fix it. Let us help.
