Název v původním jazyce
Evaluation of Elution Waste from Ion-Exchange Columns Using a Combination of Membrane Technologies
Popis výsledku v původním jazyce
Ion exchange (IEX) processes are an integral part of many water and food treatment industries, designed to reduce the concentration of undesirable ions in water. During water treatment, the ion-exchange resin becomes depleted and saturated, requiring regeneration. Regenerants, typically NaCl, strong acids, or bases, are used for this purpose. However, this process generates a significant amount of liquid waste that is challenging to treat before discharge, primarily due to its low pH, high pH, or salinity.This project aimed to evaluate the feasibility of using a combination of different membrane processes to recover a substantial amount of water. Another objective was to produce acids and bases at the concentrations required to regenerate the ion-exchange resins. The membrane processes investigated in this project include nanofiltration (NF), reverse osmosis (RO), bipolar electrodialysis (EDBM), and electrodialysis reversal (EDR).
