pH is an abbreviation for ‘power of hydrogen’. It is the negative log of hydrogen ion concentration in a water-based solution. With the pH of pure water being 7, drinking water and other natural water exhibits a pH range because it contains dissolved minerals and many gases. Surface waters typically range from pH 6.5 to 8.5 while groundwater ranges from pH 6 or 6.5 to 8.5.
The pH scale is a logarithmic scale that reads from 1 to 14. Each pH value less than 7 (the pH of pure water) is 10 times more acidic than the higher value and each pH value greater than 7 is 10 times less acidic than the one below it.
How to get your acidic water pH neutralised with our filters
To raise the pH of incoming water, you need to install one of our acid neutralisation filters (ANFs), which will have the effect of totally neutralising the acidic water. The inside of our filter vessels contains a filter media called Calcite and, as the water passes through the filter, the Calcite’s calcium carbonate neutralises the acidic water. This process will slightly increase the hardness of the water, but normally not enough to cause any scaling.
