an anion exchange membrane (aem) was used to separate hcl from nacl brine in a pilot scale experiment. the performance of the membrane under different feed temperature, nacl concentration, and feed flow rate was investigated. the results indicate that the hcl flux increased with the increase of nacl concentration and that the nacl flux decreased with increasing feed temperature. the optimum nacl concentration for hcl and nacl flux was found to be 5.00 wt%. under the optimum conditions, the hcl flux was found to be 18.62 l/m2hr, which is almost three times higher than the hcl flux reported for typical membrane process
in this study, the membrane electrochemical system (mes) was used for the treatment of an anaerobic sludge with addition of nacl and hcl as co-substrates. the effect of nacl and hcl concentration on the performance of the mes was investigated. it was found that the highest cod removal efficiency of 93.
the development of an alternative and efficient process for wastewater treatment is very important in the field of wastewater treatment. the existing processes such as biodegradation, adsorption, and membrane filtration are expensive, time consuming, and ineffective methods to remove the pollutants from the wastewater [ 14 ]. membrane filtration is the most widely employed, cost-effective, and efficient method for the removal of organic pollutants from the wastewater. however, the use of membranes is restricted by several factors such as mechanical, hydraulic, and economic constraints [ 14 ]. due to the restrictions in the use of membranes, a variety of alternative methods including adsorption, coagulation, and electrochemical processes have been developed to overcome the membrane limitations [ 13, 15 ].

separation of sulfuric acid from a dilute solution involved a plate and frame type electrodialysis unit using a commercial anion exchange membrane. experiments were conducted in batch with catholyte concentrations ranging from 1 to 5 wt%. effect of applied current density, initial catholyte concentration and initial concentration difference of catholyte and anolyte on the molar flux was studied extensively. the maximum molar flux was estimated to be 10.5210-8 mol cm-2s-1 at 4.45 wt% catholyte concentration and applied current density of 30 ma cm-2. current efficiencies were observed to be 75 to 85% at lower current density, which rose to more than 100% at 20 and 30ma cm-2, at equal initial concentration of catholyte and anolyte. diffusive flux and flux due to membrane potential contributed very less compared to total flux in presence of applied electric current. an equation was developed to predict the practical molar fluxes, which fitted satisfactorily with minor standard deviation. pristine and used membrane specimens were characterized using fourier transform infrared spectroscopy (ftir) and scanning electron microscopy (sem).
