TOTAL Mitteldeutschland Refinery presents a case study on wastewater reuse at Aquatech Amsterdam
Total Raffinerie Mitteldeutschland wants to decrease its water consumption in order to further improve their environmental footprint. In order to achieve this, it is necessary to implement a treatment train that can treat the effluent of the wastewater treatment plant for reuse as boiler feed.
As Total could experience first hand, polymeric membrane-based MBRs cannot always cope with the high fouling potential of complex and highly varying refinery wastewater, rendering them technically or economically infeasible. For this reason a 4-month field trial was conducted with akvoFloat™ –a flotation-filtration technology based on novel ceramic membranes– which was designed to treat extremely challenging industrial wastewater. The results showed in this presentation demonstrate that the target water quality could be met reliably and the permeability of the membranes could be fully recovered at all times, making the operation of akvoFloat™ stable and cost-effective.
