Reverse osmosis membranes have been shown to significantly reduce total dissolved solids, heavy metals, organic pollutants, viruses, bacteria, and other dissolved contaminants. Experience from commercial membrane wastewater treatment plants has demonstrated that key design parameters must be followed to prevent rapid membrane fouling, and thus reduce high system maintenance costs and significant downtime. Current best practices include the use of ultrafiltration or microfiltration membranes to remove colloidal debris, maintain a chloramine residual to prevent bio growth, select proper anticipant chemicals used.
Reverse Osmosis Is a new filtration technology that uses a semi-permeable, thin membrane with pores small enough to pass pure water through while removing larger molecules. It can remove dissolved salts and other impurities such as bacteria. Reverse osmosis is used to produce highly purified water for drinking water systems, industrial boilers, food and beverage processing, pharmaceuticals, seawater desalination, and many other uses.
