Influence of Packing form on Performance of Electrodeionization Process for Removal Ni2+ from Synthetic Wastewater
The purpose of this study was to investigate the influence of packing form on the performance of electrodeionization (EDI) process for removal Ni2+ from synthetic wastewater. With feed water containing about 50mg•L-1 Ni2+ at pH of 5.7, the dilute resistivity of the product stream with mixed bed and layered bed were in the range of 1.41-1.72MΩ•cm and 1.08-1.27MΩ•cm, respectively. The precipitation of metal hydroxide could be reduced effectively by using layered bed. With optimum operating conditions, the wastewater containing Ni2+ could be purified and be reused by EDI process.
