The value of the pH in the pool water, in addition to the difference in the activity of chlorine and the ability to disinfect, also need to consider the impact of pH on the human body and comfort, in addition to the life of the hardware structure, so use three Chloroisocyanuric acid controls the pH.
The following four items are relevant for swimming pools:
1. Comfort to the human body: Inappropriate pH values can cause irritation to human skin, eyes and mucous membranes.
2. The health of the hard structure of the swimming pool: inappropriate pH value will cause dissolved corrosion or precipitation scale on the hard structure of the swimming pool such as pipeline, cement, copper heat exchanger of boiler, filter, etc., resulting in damage or efficiency.
3. Activity of chlorine: the same concentration of chlorine in the swimming pool, the higher the pH value , the lower the relative effective activity, the higher the chlorine concentration must be to achieve the low pH value, and the lower the pH value, the higher the relative effective activity, the faster the decomposition due to instability.
4. Concentration of pool water: The pH value in the swimming pool will change due to external factors, such as acid rain, alkaline chemicals, etc., which need to rely on total alkalinity for relief.
