D. Tech. Chemical Engineering === Concerns for the limitations of conventional technology for acid mine water treatment and the potential use of waste water have led to increased interest in membrane technologies. Studying the physical properties of nanofiltration membranes is a very important development in nanofiltration separation process. For optimum separation performance, the nanofiltration membranes have to possess certain physical properties, given the appropriate interactions with solutes in the process stream. This study investigated the performance evaluation of Nano-Pro-3012 and NF90 membranes in the treatment of synthetic wastewater effluents and acid mine water and the influence of membrane characteristics on retention in nanofiltration. The research was aimed to evaluate the performance of a new acid stable nanofiltration material (Nano-Pro-3012) produced by Bio Pure Technology for the removal of heavy metals from shaft 8 at Rand Uranium wastewater treatment plant and compare with a commercially available nanofiltration membrane.
