According to WHO criteria, the ideal pH level of drinking water is often in the range of 6.5 to 9.5. An aesthetic objective of ≤500 mg/L has been established for total dissolved solids (TDS) in drinking water by WHO.
The TDS is directly proportional to pH, for mineral water TDS is 30 ppm. But each country different parameters. according to USA the TDS is 500 ppm. One of the most misunderstood aspects of water is it pH level. In recent times, there are many claims being made about the advantages of drinking alkaline water that is said to be rich with antioxidants, and has the ability to slow down degenerative diseases and slow down ageing. According to some doctors, our body is anyway designed to adjust to its ‘optimal pH balance’. Once alkaline water enters your stomach, your body simply pours in greater amounts of acid to neutralize it.
