This study presents a novel desalination technology that couples Donnan dialysis (DD) with thermally-recoverable solutes and utilizes low-grade heat as energy input. In the proposed process, saline feed streams receiver solutions of concentrated NH4HCO3(aq) flow stepwise across cation- anion-exchange membranes. The large transmembrane concentration differences NH4+ HCO3– set up electrochemical ...

cyanide ion, is an environmentally significant pollutant in many industrial wastewaters.therefore, a considerable number of methods have been studied for the wastewater treatment containingcyanide. the goal of our work consists in applying a simple and economic process for solving this problem ofpollution. the removal of cyanide ions by using three anion exchange membranes has been studied unde...
