| Abstract: | The combined reverse osmosis and electrodeionization(RO-EDI) process was used for treating nickel in water under different operational conditions.Experimental results showed that this combined process had high efficiency in purifying the nickel-containing wastewater.It could reduce the Ni2+ concentration from initial 200 mg·L-1 to lower than 0.5 mg·L-1.The optimum operational conditions are: a pressure of 1.5 MPa for RO;a Ni2+ concentration of 1600 mg·L-1 in the RO concentrate;and a current density of 7.5 A·cm-2 and a hydraulic retention time of 4 min for EDI. |
