dc.description.abstractElectrodialysis (ED) is a method that shows a good potential to separate and concentrate hydrochloric acid while unreacted glucose are partially recycled. Two sections of experiment had been done; section A and section B. Section A of the experiment was carried out using hydrochloric acid and glucose mixture with different concentration of hydrochloric acid in feed and product stream; voltage supplied and feed flow rate using anion-exchange membrane (PC Acid 60) and cation-exchange membrane (PC-SK) in batch mode. The main parameters which quantify the performance of the process are the duration of completing the separation, the maximum recovery level of the acid, the average product flux, the current efficiency and the energy consumption. Section B of the experiment was done based on chosen effects from section A, which were the concentration of hydrochloric acid in feed stream, the voltage supplied and the feed flow rate, under constant parameters of concentration hydrochloric acid (0.1M) in product stream and glucose concentration (5 g/l) in feed stream. This had been done using design of experiment (DoE). A central composite design (CCD) and response surface methodology (RSM) were used to obtain the optimum values of the parameters. It can be conclude that under optimum conditions (0.1M HCl in feed and product stream, 1.47 mL/s of feed flow rate,voltage supplied of 21.21V and sampling time of 100 min), the best results of energy consumption, recovery percentage and average flux were 37.93kW.h, 97.4% and 5.3kmol/m2.s.en_US
