Reverse Osmosis

Products Description:

Reverse osmosis (RO) is one of the most effective processes for providing a consistent supply of high purity water in healthcare applications. Typically, an RO system works by feeding a conventional mains supply under pressure into a module containing a semi-permeable membrane. The membrane removes a high proportion of impurities, including up to 98% of inorganic ions, together with virtually all colloids, micro-organisms and macromolecules, with almost 70% - 80% of the feed-water passing through the membrane as a purified permeate, with impurities being removed in a residual concentrate stream that is run to drain.

RO systems generally include a pre-treatment package designed to meet the characteristics of the feed-water. Typically, this equipment includes a combination of multi-grade sand filter, Ion-exchange softener and Ultrafilteration to remove Suspended solids, hardness, Silica and microbial load that would otherwise shorten life of the RO membranes. Further protection being provided by passing the water through activated carbon filters or by dosing SMBS, to remove free chlorine and organic contaminants, with any remaining particulates being removed by a fine filter before the pre-treated water enters the RO plant.
