Why use magnodol

Many borehole water or spring water supplies have a pH of less than 7. If your water supply has a pH of less than 7, it is considered to be acidic and must be treated. Acidic water can cause various problems, such as staining and corrosion. The water filter media used in a pH neutralising filter is crushed and processed limestone, called Magnadol. Magnadol can usually raise a pH from 6 to 7.

The Magnadol dissolves into water as it passes through the filter and the natural alkalinity of the Magnadol (pH neutralising water filter media) raises the pH. Because of the calcium level in the Magnadol, the hardness of the water is affected. The hardness would be expected to rise around 50ppm. Periodically, the pH neutralising filter will backwash, which changes the water flow through the water filter. The water in the backwash cycle flows in from the inlet down the centre riser tube, up through the Magnadol bed and out of the control valve to drain. The next step in a pH neutralising filter regeneration cycle is rinse. The water in a rinse cycle of a pH neutralising filter flows as in service, down through the composite pressure vessel and Magnadol filter media and up through the centre riser tube through the neutralising filter control valve and to drain. The pH neutralising filter then returns to its normal service position.
