Water with a pH lower than 7 is considered to be acidic and potentially damaging causing staining and corrosion. Treatment, by means of a pH correction filter, involves the use of a neutralising media, generally composed of crushed and processed calcite.

This media dissolves into the water as it passes through the filter and the natural alkalinity of the filter media raises the pH. It is important to note however that due to the calcium level within the filtration media, the hardness of the water is also affected and may be expected to rise by around 50ppm. In such instances additional treatment by a water softener may also be required.

pH correction filters are available in different sizes. If you require technical support and assistance; or if you simply have a question about pH correction flters, please contact one of our specialist advisors.
