re·verse os·mo·sis (rĭ-vûrs′ ŏz-mō′sĭs, ŏs-)
A technique for purifying water, in which pressure is applied to force liquid through a semi-permeable membrane in the opposite direction to that of normal osmosis.
Great beer is only as great as its ingredients. Grain, hops, yeast and water, all must be of the highest quality to ensure high quality beers. Since beer is mostly water, it makes sense that the water used in making the beer is of the utmost highest quality and purity. Reverse Osmosis (referred to as RO) water treatment is one of the most effective and thorough methods to effectively remove undesirable additives and other contaminants from a water supply. The RO process is particularly effective in removing chlorides, dissolved solids and fluoride from the water supply. Fluoride, for example, is not removed by traditional paper or charcoal filters and is concentrated in the brewing process if not removed.
