【Abstract】 By combining electrodeionization(EDI) with electrodialysis, the experimental study has been done for the process of EDI. The influence of the raw water conductivity and the electric current on the EDI stack etc. were investigated. The optimal operating conditions of EDI stack were discussed.It was found that the high quality pure water can be obtained by increasing the current of the EDI stack.At the same time, the lower influent conductivity and increasing the influent flow were helpful to improve the product water quality.更多还原
