How to reduce the water temperature in the aerobic tank
Thread Content
As is well known, the water temperature in the aerobic tank has a significant impact on bacteria and the operation of the system. In summer, as temperatures rise, so does the water temperature in the aerobic tank. When this temperature exceeds 35°C, it begins to affect the operation of the system, and when it exceeds 40°C, problems start to arise. So, what are some good ways to lower the water temperature in the aerobic tank?
Cooling tower + heat exchanger. Personal opinion, for reference only
Could you be more specific? Where to add it, how to add it, how to achieve heat exchange, and what coolant to use.
When the water temperature in the aerobic tank exceeds 35°C, it begins to have an impact on operation; when it exceeds 40°C, operational problems start to occur. Our situation is as follows
You are relatively happier, but isn’t the water temperature lower in winter as well?
Increase the sludge circulation rate; even self-circulation can be considered. Increase the aeration volume. After all, the water temperature in summer is only around 40°C, so a cooler or something is probably not necessary.
The raw water temperature is controlled at around 30°C； Increase the outflow rate, increase the water distribution in the regulating tank or equalization tank to lower the water temperature, etc. At 40°C, the duration is not long; control mainly remains at the raw water level.
Personally, I think maintaining good ventilation is key; if it’s caused by too high water temperature, a cooling tower can be installed. If the aerobic tank has a roof, it hinders cooling; it is best to have strong ventilation. If it is outdoors, the temperature generally will not rise to 40 degrees. Also, control the temperature of the incoming water – it shouldn’t be too high; around 25 degrees is ideal.
