Hi guys! I've searched the forum for about an hour now and didn't see an answer for this so any help is appreciated.
How do most of you clean the scale out of your cooling towers? Normal procedure here is to shut down the tower and valve it off, then add a descaling compound into the basin. After it soaks for a few days, then we drain the tower and scrape off the scale with paint scrapers. Does that seem ok to you?
The problem right now is that some of the crews didn't do their annual cleaning, and my crew is picking up the slack. The daily temps are rising here and we don't really have the luxury of letting the unit soak, so we are having to scrape the scale off without first using the descaler.
I'm curious as to what you guys normally do, and what you would do in this situation.
2nd question: Occasionally the units begin to leak. We remove the old silicone from around the inside of the basin and reseal everywhere, but when we refill the unit, there is still a little seepage. Is there a trick that we should be doing to help ensure that the units seal well?
Background info: I am a new supervisor at a utility plant. My background is in electrical and generators, so some of the HVAC equipment is new to me. Any information that you have is appreciated.
