Water storage temperature stratification

Increase in the water temperature typically results in chemical and thermal stratification along with an increase in biofilm growth and a decrease in the chlorine residual. The sun warms the outside of the storage tank and the heat inside increases the corrosion of metal above the water line in the headspace of the storage tank. [pdf]
