As the smallest molecule in nature, hydrogen is flexible and highly penetrating. It has low solubility in water and is easy to escape. (These characteristics determine that the amount of hydrogen dissolved is limited, and it needs to be placed in an aluminum alloy container after dissolution, otherwise It is difficult to maintain a stable hydrogen concentration in the water for a long time).
RO (Reverses Osmosis) refers to reverse osmosis water---also commercially available pure water. The principle is to apply a greater than osmotic pressure at one end of the raw water to produce reverse osmosis.
