Many people have heard of reverse osmosis and know that it can be used to treat water to a high degree of purity, but their understanding of the technology ends there. This month's article is intended to familiarize readers with how the technology works, and what it will or will not do for water contamination.

To understand reverse osmosis (called "RO" for short), it first helps to understand the natural phenomenon of osmosis. Simply put, osmosis is the flow or diffusion of a fluid--generally water--through a semi-permeable membrane.

Nature will often use osmosis as a way ...
