   Such systems do not remove minerals from the water itself. Rather, they can only alter the downstream effects that the mineral-bearing water would otherwise have. These systems do not fall within the term "water softening" but rather "water conditioning". [citation needed] Similar claims for magnetic water treatment are not considered to be ...

3. Dealkalization of water - Wikipedia

   In order to justify installation of a dealkalizer on low-pressure boilers, the alkalinity content should be above 50 ppm with the amount of make-up water exceeding 1,000 gallons (approx. 4,000 litres) per day. Cooling system make-up will also benefit from reduced alkalinity.
