Hi Group,
I have a question about water additives to eliminate rust.
At work, we have a water tank, (1500 gallons) which is used to cool a large stationary engine. The tank is in a small room, open to the atmosphere, and an external pump supplies water from the tank to cool the engine, then returned to the tank. Combining the large volume of water, and the limited use of the engine, the water temperature is never raised about 130F or so. We use a simple water filter inline to give some measure of filtering, but over time the water does get a bit of a rust buildup on the tank floor. Is there some sort of water additive that will eliminate rust? The obvious choice is some sort of automotive anti-freeze solution I suppose, but did not know if there was something out there for the larger water volume we are dealing with.
The water is changed annually, but we do not want to have any toxic additives that would not allow the water to be discharged into the parking yard behind the shop.
Any ideas out there? All positive comments welcome!
