What is reverse osmosis in water treatment?

Reverse osmosis (RO) is a special type of filtration that uses a semi-permeable, thin membrane with pores small enough to pass pure water through while rejecting larger molecules such as dissolved salts (ions) and other impurities such as bacteria.

In fact, the reverse-osmosis process removes 92 to 99 percent of beneficial calcium and magnesium. What is alarming, is that consuming RO

Reverse Osmosis (RO) is a membrane separation water purification process in which feed water flows along the membrane surface under pressure. Other requirements include prefiltration to remove suspended impurities and carbon to remove chlorine (damages the membrane).

In the reverse osmosis process, cellophane-like membranes separate purified water from contaminated water. RO is when a pressure is applied to the

A reverse osmosis system removes sediment and chlorine from water with a prefilter before it forces water through a semipermeable membrane
