| A
pH of above 7 indicates the presence of alkaline substances.
If the pH value rises above 8, the effectiveness of
the disinfection process is reduced and the water has
an increasing tendency to precipitate hard salts.
The water can become cloudy and the filter capability
reduced, due to blockage.
Acidic Conditions - Low pH
A pH value below 7 indicates the presence of acidic
substances.
If the pH falls, the water becomes increasingly corrosive
to metals and the chlorine level decreases, weakening
the disinfection process.
Finally, and most importantly, if the pH is too low
or high, irritation of the eyes and skin may be caused
by the water. |
