  • Reverse Osmosis Membrane - an overview |

    The RO unit uses thin-film composite (TFC) polyamide membranes in spiral-wound configuration. The single-pass RO system is a two-stage (6:4) membrane array designed to achieve a product water recovery (PWR) of 75% (53 m 3 /h permeate/70 m 3 /h feed). The design is based on membrane manufacturer's projections given in Table 4.1.
