How Do Reverse Osmosis Systems Work?

Many of our readers have asked questions about reverse osmosis drinking water filtration systems and want to know more about them. Hence the purpose and reason for this deviation from the normal subject matter in this Water Testing Blog entry.

“The reverse-osmosis water filter is usually installed beneath your kitchen counter. The filter commonly consists of five components: one or two sediment pre-filters, the RO membrane filter, a drain for reject water, a small treated water storage tank, and a carbon post-filter. In addition, an air gap is built into the faucet; this serves as a sanitary device by preventing wastewater from flowing back into the filter.

Most reverse-osmosis systems purify water in 3 to 5 phases. The early phases use pre-filters to remove particles of dirt and sediment, chemical contaminants, certain microorganisms, and odors; a middle phase employs the RO membrane itself to eliminate dissolved solids, metals, and other microorganisms; and a final phase actuates a carbon (charcoal) post-filter to eradicate any remaining traces of chemicals and odors, thereby improving the quality and taste of the water.
