FORWARD OSMOSIS MEMBRANE WITH HIGH FLUX AND MANUFACTURING METHOD THEREOF

摘要

PURPOSE: A forward osmosis membrane of high flux and a method for preparing the same are provided to improve flux by forming a polyamide layer containing an aqueous additive on a support based on non-woven fabric and a polymer layer and accelerating the pore formation of the membrane. CONSTITUTION: A support is based on non-woven fabric and a polymer layer. A polyamide layer contains a polyamine salt compound as an aqueous additive. A forward osmosis membrane of high flux is composed of the support and the polyamide layer by forming the polyamine layer on the support through an immerging process and an interfacial polymerizing process. The polyamine salt compound is a tertiary polyamine salt compound obtained from tertiary polyamine and strong acid.
