Reverse osmosis produces one of the purest methods of water filtration, removing up to 99% of all contaminants from water.
Water passes through a series of filters including an activated carbon filter for the removal of chlorine. After which the water passes through a semi permeable membrane that has the ability to remove and reject a wide spectrum of impurities, bacteria and contaminants from the water, producing an ultra pure product water.
Reverse Osmosis systems were originally designed for desalination and have been widely used for many years by the shipping industry, oil rigs etc for the conversion of sea water into drinking water. Now the technology is being used by hospitals, Industry and pharmaceutical companies where the purest of water is required.
R/O systems typically have the following components: A supply pump or pressurized raw water supply, prefiltration in one or more stages, chemical injection of one or more pretreatment agents may be added, a pressure pump suited to the application, sized and driven appropriately for the flow and pressure required, a membrane array including one or more membranes installed in one or more pressure tubes (also called pressure vessels, R/O pressure vessels, or similar), various gauges and flow meters, a pressure regulating valve, relief valve(s) and/or safety pressure switches, and possibly some form of post treatment. Post treatment should usually include a form of sterilization such as Chlorine, Ultra-Violet (U-V) or Ozone. Other types of post treatment may include carbon filters, pH adjustment, or mineral injection for some applications.
This technology is now available to the discerning members of the public who will accept only the highest standards in their drinking water
Reverse Osmosis systems are available in different configurations to suit individual needs.
Pre-filtration is of the utmost importance to prevent fouling of the membranes, different pre-filtration cartridges are available to suit local water conditions.
