DE-MINERALIZED WATER

REVERSE OSMOSIS (RO) IS IT A GOOD OPTION FOR DRINKING WATER HOW DOES IT WORK

Reverse Osmosis (RO) was developed to remove salt from sea water for military submarines. The reverse osmosis process draws water through a porous membrane. Salt water is put through on one side of the porous membrane and as pressure is applied it first stops and then reverses the osmosis process. It generally takes a lot of pressure and is fairly slow removing all the minerals smaller than the pores in the membrane.

Water without minerals can be a problem. Dr. Zoltan Rona comments in her book "Pure Water" against the use of de-mineralzed water produced by distillation and reverse osmosis. Dr Rona adds, "Longevity is associated with the regular consumption of hard water that is high in minerals. Disease and early death are more likely to be seen with the long term drinking of distilled water" Water produced by reverse osmosis is similar to the distillation process, purified to a point where it is devoid of healthy minerals. New reverse osmosis systems using a five stage filtering process reintroduce minerals like calcium back into the drinking water after the water runs through the osmosis process.
