Reverse osmosis purifiers (RO) are commonly used to provide pure water for the food, mining pharmaceutical industries, as well as for home consumers.

Osmosis is a process that occurs when two solutions of different concentrations are separated by a semi-permeable membrane. Water passes through the membrane in the direction of the more concentrated solution.

RO water purification works by forcing the water under pressure against an ultra –fine, semi-permeable membrane designed to allow single water molecules to permeate through, while at the same time rejecting most contaminates. The membrane acts as a mechanical filter, straining out particulate matter, micro organic compounds.

A typical RO filter purifier consists of three, four or five filters in series depending on the water quality, plus a storage tank. The first is a sediment filter to remove particulates, eg; (dirt, rust, silt) the second housing contains the ultra-fine activated carbon block, to remove any remaining chlorine by-products such as chloroform or THMs.

Once the contaminates are separated from the clean water, they are washed away so that they don’t build up in the purifier. Such a system removes a wide spectrum of impurities; the only energy required is that of mains-pressure. RO removes turbidity, sediment, colloidal matter, total dissolved solids, toxic metals, radioactive elements, pesticides, and herbicides. This can have significant health benefits. Trials at the university of Quebec in Canada in 1993 concluded that ‘individuals consuming the un-modified tap water experienced gastro-intestinal symptoms 30% more frequently than those who consumed the water after reverse osmosis treatment:

Unlike filters, RO membranes don’t accumulate pollutants, but the membranes themselves gradually degrade with use. While the sediment and carbon filters gradually degrade with use. While the sediment and carbon filters will probably need replacement every 6-12 months, membranes should be replaced every 3-5 years, or as specified by the manufacturers.
