The water with […]

pH and Drinking Water

A question often asked is what is the effect of water, with a pH lower than 7, on human health? Under certain conditions a reverse osmosis purifier will lower the pH of the permeate or purified water slightly. (This depends on the equilibrium relationship between CO2, HCO3, and CO3). To understand the effect of pH […]
