| Abstract |
This study was focused on experiment for the separation and concentration process of Cu(Ⅱ), Zn(Ⅱ) solution with the variation of applied pressure and concentration using reverse osmosis plate and frame modules. Rejection coefficient and degree of concentration for Cu(Ⅱ) component using single and multi-stage reverse osmosis process were showed 96.3 ~ 97.8%, 0.044 ~ 0.191(in single-stage), 96.3 ~ 98.4%, 0.400 ~ 2.264(in multi-stage) within the range of experimental condition, respectively. Those of Zn(Ⅱ) were 93.3 ~ 97.1%, 0.019 ~ 0.395(in single-stage), 96.3 ~ 98.2%, 0.365 ~ 1.454(in multi-stage), respectively. Degree of concentration of multi-stage were higher than those of single-stage. Heavy metal[Cu(Ⅱ), Zn(Ⅱ)] separation was very efficient in using reverse osmosis plate and frame type modules. Separation efficiency for a mixed solution Cu(Ⅱ) and Zn(Ⅱ) was higher than those of each one of Cu(Ⅱ) and Zn(Ⅱ). |
