The characteristics for the separation and concentration process of Cu(Ⅱ), Zn(Ⅱ) solution was discussed with the variation of applied pressure and concentration using reverse osmosis plate and frame modules in this study. Rejection coefficient and degree of concentration of Cu(Ⅱ) component using single and multi-stage reverse osmosis plate and frame type modules were showed 96 ∼ 98%, 0.044 ∼ 0.191(in single-stage), 96 ∼ 98%, 0.400 ∼ 2.264(in multi-stage). Rejection coefficient and degree of concentration of Zn(Ⅱ) component were 93∼ 97%, 0.019 ∼ 0.395(in single-stage), 96 ∼ 98%, 0.365 ∼ 1.454(in multi-stage).
