Three main products have been obtained as a result of the project BENTOMET: i) an industrial plant for recycling waste bentonites, which is located in Lurederra’facilities in Los Arcos (Navarra); ii) modified bentonites resulting from the constructed recycling line, which can be used as heavy metals adsorbent for wastewaters; and iii) a wastewater treatment system incorporating modified bentonites, which has been implemented into a real wastewater treatment industrial line in COOLREC facilities (The Netherlands). Such treatment system is able to remove very efficiently heavy metals from wastewaters and, then, to easily separate the saturated solid from the treated water using a magnetic device, due to the magnetic properties of the adsorbent.
