This paper presents a possibility of removing Cu(II), Ni(II) and Zn(II) ions from model and real galvanic wastewater applying the hybrid complexation-ultrafiltration process. The complexing agent applied in the research was Instar AS which contained polyacrylic acid. In order to separate the formed metal complexes, porous membranes made from polycaprolactam were used. The most favourable ratio between the concentrations of the complexing agent and the metal ions and optimum pH were determined applying model solutions. The process of concentration of real wastewater was characterized by good effectiveness and enabled an 85-97% retention of the metal present in the wastewater.
