Hot water circulation Chemical dosing
Thread Content
Does an 80°C hot water circulation system require the addition of chemicals, such as corrosion and scale inhibitors, or disinfectants?
Fungicides can be added regularly, while scale inhibitors need to be added continuously.
Is our hot water system a closed system that requires regular drainage and refilling of water? Also, does the fire protection water system need water treatment chemicals to be added?
At 80°C, bacteria generally grow quite well; although the temperature is high and the dissolved oxygen level is low, it is still necessary to add disinfectants regularly to prevent the proliferation of anaerobic bacteria under such high-temperature conditions； The addition of scale inhibitors must be done in a timely manner, as scaling occurs more rapidly at high temperatures compared to normal temperatures.
Scale inhibitors and corrosion inhibitors can be added. Add fungicides regularly. Should the water used for rehydration be soft water or tap water? At high temperatures, the solubility of calcium carbonate decreases, making scaling more likely.
