摘要

In recent times, due to the increase in water crisis and the population quantityrnand density, the development of emerging water desalination techniques are crucial.rnElectrodialysis reversal (EDR) process is the advanced water treatment processrnflourishing these days. EDR is based on the principles governing the behavior of ionicrnsolution when subjected to direct current potential. EDR can be designated as thernmodified form of ED (Electrodialysis) i.e. introduction of reversal process to ED.rnThe EDR performance can be evaluated by three important parameters likernSeparation Percentage (SP), Current Efficiency (CE) and Thermodynamic efficiencyrn(TE). This works throws light on EDR performance by mainly evaluating parameterrnSP. The SP can be defined as the amount of salts removed from the feed water tornobtain a portable product. The main aim of this work is to study the influence of thernoperating factors like temperature, flowrate, voltage on SP at two differentrnconductivities of water. The design of experiments (DOE) is two and three levelrnfactorial design where the different experiments are conducted at the differentrnflowrate, temperatures and voltages. The water analysis data is utilized to carry outrnthe calculations and plotting of graphs.rnGraphs are plotted for SP with each of the operating factor to understand therneffect of the operating conditions on SP. Therefore, a generalized relationshiprnbetween SP and operating conditions is studied. Water, when subjected to electricalrnpotential generates both cations and anions. Graphs are plotted for individual cations.
