Often these waters can be of high quality and are low in buffering calcium minerals, but are high in dissolved carbon-dioxide gas, which can cause the low pH or acidity.
Treatment is accomplished by neutralizing the water with the use of an automatic neutralizer .
These water filter tanks are filled with a blend of calcium and magnesium carbonates made from naturally occurring minerals, which dissolve into the water, making it less corrosive. In some cases, instead of dissolved carbon dioxide causing the low pH or acidity, the acidity is caused by mineral acids, either natural or from mining or other industrial wastes. Often the pH is very low, less than 5.0. Treating this type of water requires injection of soda ash or sodium hydroxide with a metering pump , and generally, the neutralizing type mineral filters decribed above will not work well on this type of water.
