Brief Description

Description :

This technology involves the integration of membrane separation processes with ion-exchange resin columns to produce demineralized water suitable for multiple applications. The system combines the advantages of membrane filtration for removal of bulk dissolved solids and resin-based ion exchange for polishing residual ions, thereby ensuring high purity output. It is designed to operate at capacities ranging from approximately 25–60 L/h and can be used in applications requiring consistent demineralized water quality. The integration improves efficiency by reducing load on individual components and enhances overall system performance and reliability. Key Features: • Hybrid system combining membrane filtration and ion-exchange resin columns • Enables efficient removal of dissolved salts and residual ions • Produces high-quality demineralized water suitable for multiple applications • Improves overall system efficiency by distributing treatment load • Compact design suitable for moderate capacity operations (25–60 L/h)
