Charged Membrane Low Pressure Ultrafiltr

Low-pressure ultrafiltration with negatively-charged, non-cellulosic membranes is shown to be a feasible process in terms of achieving the simultaneous separation of various contaminants from acid mine drainage waters. The objective of this research was to evaluate the effectiveness of charged membranes in treating acidic effluents commonly associated with mining operations. The methodology involved testing different membrane materials and configurations to optimize the filtration process while assessing parameters such as permeability, solute rejection rates, and operational pressures. Results indicated that the negatively charged membranes exhibited enhanced separation capabilities for metal ions and suspended solids, which are prevalent in acid mine drainage. The findings suggest that employing low-pressure ultrafiltration can significantly improve water quality and facilitate the recovery of valuable metals, thus offering a viable solution for mitigating pollution from mining activities. This research contributes valuable insights into water resource management by demonstrating an effective approach to treating contaminated water while promoting sustainability through resource recovery.
