Processes of Ultra- and Nanofiltration for Cleaning Solutions from Iron Colloid Substances

Abstract:

The application of NF90 membrane was shown to be the most effective for the removal of silicon and iron ions and organic substances from natural water. In this case, the membrane retention capacity amounts to ~ 86.0 % for silicon ions. The application of GR81PP and GR95PP membranes was shown as the most effective for the removal of iron ions and organic substances from natural water. In this case, the membrane retention capacity amounts to ~ 86.0 % for organic substances and 99.8% for iron ions. Therefore, the processes of ultra- nanofiltration can be used as a post-treatment step for groundwater of Western Siberia.
