Adding a squeeze of lemon or lime to a glass of water can make your water more alkaline as your body digests it. Adding pH drops or baking soda is another way to make water more alkaline.
How do you naturally pH your water?
If the pH of water is low in that case soda ash or sodium bicarbonate can be added to water to increase pH value. Naturally, we can also do it by adding clean rocks or quartz porphyry to the drinking water to increase pH. On the other hand, citric acid or vinegar can be added to decrease pH value of water.
How do I lower the pH in my tap water?
Soda ash/sodium hydroxide injection
This treatment method is used if water is acidic (low pH). Soda ash (sodium carbonate) and sodium hydroxide raise the pH of water to near neutral when injected into a water system. Unlike neutralizing filters, they do not cause hardness problems in treated water.
