Phosphorus removal using nanofiltration membranes

Water Science and Technology, 2011
A high concentration of phosphorus in wastewater may lead to excessive algae growth and de-oxygenation of the water. In this work, nanofiltration (NF) of phosphorus-rich solutions is studied in order to investigate its potential in removing and recycling phosphorus. Wastewater samples from a pulp and paper plant were first analyzed.
