RO System :

Ro Systems Reverse osmosis has become one of the most cost efficient technologies to purified water. reverse osmosis does not use expensive and hazardous chemicals, it has replaced ion exchange demineralization in many applications such as boiler feedwater treatment, rinse waters, laboratories, drinking water , mineral water system ,etc.

Reverse osmosis uses membranes wound around a core in order to fit large amounts of membrane surface area into a small volume. Such membranes are referred to as "spiral wound" and have largely displaced the early "hollow fiber" systems. Since the membrane prevents 98% of dissolved ions from passing into the clean water stream, a lot of minerals are left on the "dirty" side of the membrane. To sweep these away and minimize scaling (as the minerals become more concentrated, many may exceed their solubility concentration and begin to precipitate or scale onto the membrane, thus decreasing its filtration efficiency and potentially rendering it useless, typically about 25% of the total feedwater is washed across the dirty side of the membrane to drain. In addition to the concentrated minerals, much of the tiny particles of suspended dirt in the feedwater are also swept to drain. This produces a very clean product water since even very small particles (down to 0.0001 micron), including most total organic carbon or TOC is also removed.
