Question by $ree: How to maintain the temperature of water in a water recycle system (31 to 34 Celsius)?
I have a water recycle system. The problem is the temperature of the output water is a bit high (38 to 43 Celsius) than my need (31 to 34 Celsius). Now I am maintaining this by mixing fresh water to it. But it is not cost effective. Please give me another solution to keep it low. Thank you.

If the system is small enough put the water through a radiator. A fan to blow over and through the radiator may be enough. A thermostat controlled water drip can be added for additional cooling.
Maybe putting the radiator in a larger water filled tank will work.

Well, this is not at all clear.
I presume you have some sort of closed circuit coolant system using water, and that is what you are asking about.
Since it isn’t clear how the system is set up, nor any details on mass flux and system size, storage buffers, and all that, or really, even where you live (climate), or what sort of mechanical fixes are feasible, it is impossible to really advise you.
If you live in a climate where air temperature is well below your target temperature of 31 to 34 degrees, the best solution would apparently be to divert the flow to cooling towers or some such similar system. Some sort of roof-mounted cooling stack is common for this type of closed coolant system. You have to get the heat outside the building.
Of course, if the air is pretty close to your target range, it will be difficult to cool down to that temperature without incorporating some tertiary coolant system. Cheapest would be using water spray to cool the coils in your stack, but then, you don’t want to use new water, so that idea is probably out.
