What is the acceptable pH range for treated water?

The acceptable pH range for treated water is critical in ensuring the safety and efficacy of water for various purposes, especially in medical and industrial applications. A pH level of 6.8 to 7.4 is optimal for treated water as it closely aligns with the physiological pH of human blood, which averages around 7.4. This range minimizes the risk of corrosion in plumbing systems and reduces the potential for leaching of metals from pipes, which can occur at more acidic pH levels. It also helps in maintaining the stability of certain chemicals used in water treatments and aids in preventing the growth of harmful microorganisms.

Choosing this range ensures that the water is suitable not only for patient care but also for other sensitive applications where pH can significantly impact chemical reactions, solubility of compounds, and the overall safety of the water. Therefore, maintaining a pH within 6.8 to 7.4 is essential for achieving high standards in water treatment processes.
