摘要: AbstractThis work is concerned with the feasibility of surface water desalination by neutralization dialysis (ND) process and difficulties related to it. The pH conductivity model saline solution have been measured during different ND operations, using a three-compartment membrane stack 64 cm2 active area for each ion-exchange (IEM). concentration maintained at 0.02 mol L−1. influence three parameters has investigated, i.e. flow rate (from 35 100 mL min−1), alkaline concentration, acidic 0.02 0.1 mol L−1). We shown that diffusion boundary layers great on kinetics through IEMs. A leakage HCl cation-exchange proved. Its more pronounced when concentrations are low. These leakages modify shapes vs. time curves, de...
