BRANEX LE membranes are manufactured by optimizing the formulations and process conditions of both the support layer and thin-film composite (TFC) layer—resulting in tailored adjustments to membrane density and performance properties. Compared to conventional brackish water RO membranes, these elements deliver a 99.3% rejection rate while operating at a 30% lower pressure. The integration of this membrane element cuts RO system energy consumption by up to one-third, all without compromising product water quality. LE RO membranes are available in 4” and 8” configurations to suit diverse system requirements.
