Performance Identified Technology of Ion Exchange Membranes & Recovery to Acid and Alkaline Technology (R2A):材料世界網技術櫥窗

Performance Identified Technology of Ion Exchange Membranes

■ Technology Overview

Developing the rapid screening tests for membrane performance including moisture content, membrane resistance, ion exchange capacity, permselectivity, swelling degree, acid and alkali resistance, and burst

strength has been a characteristic indicator for membrane materials development. In addition, we also build the standard module for system function testing and provide the standardization test process for quick screening of the electrodialysis performance.

Recovery to Acid and Alkaline Technology (R2A)

Zero Liquid Discharge (ZLD) System Market size will surpass USD 9 billion by 2025; according to a new research report by Global Market Insights Inc.

Due to the strict regulations on wastewater disposal, freshwater scarcity, high cost of wastewater recovery, and increasing public environmental awareness, developing novel technologies for brine management and treatment is urgently needed.

R2A is a technology that converts ions in wastewater into valuable substances. It uses membrane-based electro-Separation process to separate and convert the anions and cations in the wastewater into acid and alkali solutions separately. In comparison with conventional thermal processes, the non-thermal ZLD process, R2A, for brine treatment shows the capability of valuable resource in-line recovery in liquid phase with less energy consumption and environmental impact.
