I'm thinking it's unworkable because I haven't been able to google someone else doing it. I've been thinking of flood coolant and bacteria problems. Seems to be a merry go around with no real ideal solution, oil skimmers, running aerators, swapping the coolant often, using bleach (contested) or other biocides (possible other side effects) and maybe something else that I've missed. Now what I was thinking, why not install a heating coil in the coolant container and set it to heat the flood coolant to say 75C one day every week, perhaps during night so it won't bother anyone.
I thought of this because our heat pump in our house has a program that weekly increases the water temperature to prevent legionella from forming in the reservoirs. Also pasteruized a bunch of apple juice earlier. Thought maybe this could be adapted to flood coolant as well, at 75C most bacteria should be well dead. Problems I see would be if the temperatures in that range might affect the composition of the coolant, and the increased evaporation of such a process, though if you keep the coolant in a well sealed container it shouldn't be too bad, the built in sump might not be good enough for this, and hot water and moisture would make rust issues worse, so a separate container is probably better, maybe built from stainless.
Anyway is there anything obvious I am overlooking that makes this not work, because if it worked I feel someone would have come up with it already...
