pH correction systems from Global Water Solutions are self standing pressure vessels - designed to correct the pH level in your water.
How does the pH correction system work?
pH correction occurs by the following process. Calcite is a natural 'Rock' like substance, and exhibits an alkaline pH.
As low pH water (acidic quality) passes through the bed of calcite, the calcite slowly dissolves and the result is an addition of dissolved calcite in the water, in turn, stabilising or 'correcting the pH level in the given water.
When this system is not in use, pH will rise to approx. pH 7(this is considered a neutral level). As the water is then, no longer acidic, the action ceases until water flow is re-established.
This acts as a simple regulator, so that the level remains as near to neutral, as possible. Acidity (pH) in more detail.
Water which
contains excess acidity tends to act aggressively towards plumbing and
fixtures, causing corrosion and staining (i.e.-blue green stains on
fixtures from copper pipes). Relative acidity/alkalinity is measured on
the pH scale, ranging from 0- 1 4, where 7 is neutral, numbers lower
than 7 are progressively more acidic, and numbers higher than seven are
increasingly alkaline (basic). The pH value refers not to the quantity
of acidity, but rather to the relative acidity/alkalinity of a
particular sample.
Alkalinity acts
as a buffer to deactivate the acidity, a process called neutralisation.
For example, limestone (calcium carbonate) is often applied to soil to
offset the acidity which comes from acid rain and decaying organic
material. The acceptable range for water is 6.5-8.5.
Acidity cannot be
removed from water. However, it can be neutralised by raising the pH
with alkalinity. This can be done by injecting a basic
(alkaline) solution with a feed pump, or by passing the water through a
bed of calcite or limestone as explained above.
