Ion exchange resin

The negatively charged polyamide thin-film-composite nanofiltration membranes have been used to possibly treat the sodium-enriched water, particularly cooling tower water, to separate hardness producing solute like MgSO4 from univalent salts using ESNA and EDA nanofiltration membranes. The flux decl

Acetic acid is a compound commonly found in hemicellulosic hydrolysates. This weak acid strongly influences the bioconversion of sugar containing hydrolysates. Previous investigators have used anion exchange resins for acetic acid removal from different hemicellulosic hydrolysates. In this study, th

The reuse of water coming from electrolysis manufactory effluents is studied by means of the electrodeionisation technique. A neutral water stream which contains small quantities of zinc, copper, cadmium and lead is treated. Results obtained by electrodialysis and ion exchange by resins are presente
