tony searles are they actual nanoparticles or are this metal present in the aquifer your tapping in if they are in ion form Al3+ , Ba2+ and Sr2+ then you cant re move them directly by microfiltration. It either will require nanofiltration or a chemical treatment as prescribed by other posts. we treated in the past Ca++ Sr++ and Ba++ by lime softening followed by MF and polishing stage electrocoagulation and a second MF stage the starting concentration were extremely high. Depending on volume and concentration you could also look at ion exchange. if you want a further chat don't hesitate to contact me.
