pH Treatment Units

pH (pondus hydrogenii) is an indication for the acidity level of a substance. In areas of low pH (soft water), the acid effect of the water can corrode the inside of copper water pipes and immersion heater tanks, slowly leading to costly leaks and immense inconvenience. The tell tale sign that can accompany water of a low pH is a blue/green staining around and under taps in basins, baths and showers.

In areas with water of a high pH level, water is generally speaking "hard", thus it will contain minerals such as calcium and magnesium. Hard water can be treated with dedicated water softening equipment.

Acidic, or soft water can have its pH level corrected with a correction unit that contains a correction media that will raise the pH to neutral. Our pH correction units use calcium carbonate (trade name CALSAN) as a correction media. Calcium carbonate is only dissolved by the acidity in the water and is not water soluble. For this reason, the water only uses enough of the calcium carbonate to correct the pH up to the neutral level and will not overdose as is the case with most lime based medias that can be over-absorbed and lead to a bitter tasting water.

The rate of usage of the calcium carbonate is dependent on the pH of the water entering the unit and the amount of water usage. The peak flow rate of the water determines the size of the unit required, this is to allow an ample area of media in the unit to correct the pH. Too small a unit and the water does not make contact with the calcium carbonate for long enough to be completely neutralised.

pH treatment equipment is available for residential households, right up to sizes suitable for commercial use. Advice should be sought in order to obtain a system suitable for your specific needs.
