Membrane
Spiral type module (RO)
Reverse osmosis is a technique for separating water from dissolved matter by applying a pressure of more than the osmotic pressure of the treated raw water to the treated raw water (normally, around 1MPa to 6MPa) using asymmetrically structured membrane or composite membrane which has ability to block the dissolved matter. It is used in many areas for the purposes of desalinization, removal of low molecular weight substances whose molecular mass is 1,000 or less and so forth.
