摘要：Novel low pressure reverse osmosis and nanofiltration membranes and aprocess for their preparation are disclosed. Polyamide reverse osmosis membranes arecontacted with organic sulfonic acid solutions without the need for additional treatmentby a rejection enhancing agent. These membranes provide sodium chloride rejections ofgreater than 20 percent and water fluxes greater than 15 gallons per square foot perday at a test pressure of 75 psi. Optimally treated membranes when tested similarly on0.2 percent magnesium sulfate provide rejections greater than 95 percent with waterfluxes greater than 15 gallons per square foot per day.
