Methods for controlling pH in water sanitized by chemical or electrolytic chlorination |
摘要 |
The invention relates to the control of pH in water where hydroxyl ions are being produced by adding to the water an amount of transition metal salt sufficient to bind with hydroxyl into a slightly soluble or insoluble reaction product, thereby removing sufficient hydroxyl ion from the water to lower the pH thereof. This technique is particularly suitable for pH control in pool or spa water that is sanitized using chemical or electrolytic chlorination, where the sanitation process causes the pH in the water to rise.
