cooling water after process
(OP)
Hello, im looking for diffrent ideas to cool water. Basically i have city water at 65f that runs thru copper and runs out of drilled holes over a hot drum which heats it up to about 102f and then runs into a drain...big waste, not to mention big water bill. So we would like to re-use this water by re-useing it and bringing the temperature back down to 65F. in basically an endless cycle. We are in the north east so winter weather is a factor and 65f is the optimal temp of the water we need at the start. Thanks for any ideas

If you have lots of available real estate you can spray the water into open ponds. You'll get some cooling from the spray stage and the rest by exchanging heat with the air but this is going to give you warmed water than a cooling tower.
A lot is going to be driven by your water costs. What sort of payback would be needed? That and your current water cost would give you an idea of how much the system could cost and some phone calls to vendors would let you know if it was even feasible to pursue.

The optimal solution will depend on the economics of the problem, including capital equipment costs, the cost of power and water in your area.
A friend of mine had a photo lab (back in the old days of film) that required a few GPM of cool water to control process temperatures. The original installation just took city water, ran it through the heat exchanger and dumped it into the drain. After the city started hitting him up with big water bills, he acquired a drinking fountain chiller and pump. Plumbed the thing into a loop to recycle the water and (by his estimation) saved quite a bit of money (Seattle WA power rates were low back then).
