Abstract:
An acid mine drainage (AMD) treatment means comprising polyethersulfone (PES) having dispersed therein hydroxy-sodalite (H-SOD) so as to form a membrane is described. The PES-H-SOD membrane is suitable for treatment of acid mine drainage (AMD) by providing a filtration means to remove toxic chemicals, including but not limited to heavy metals. The invention extends to a method of manufacturing the acid mine drainage (AMD) treatment means.
