KMS supplies first large-diameter SWRO system

Koch Membrane Systems

The port facilities for Chile's Minera Esperanza copper/gold mine will soon be provided with drinking water from an innovative new seawater reverse-osmosis (SWRO) system supplied by Koch Membrane Systems (KMS). The system is the first full-scale large-diameter membrane RO system for seawater that KMS has developed.

The system uses KMS MegaMagnum® high capacity seawater membranes, made from a unique thin-film composite developed specifically for seawater applications. The original pilot operates at a rate of 20 m³/h.

Upon completion of the installation of the second phase of the project, this unit will be removed and will be replaced by the permanent RO system consisting of two new MegaMagnum MM2 units, which will provide the port facilities with a capacity to store about 80 m³/h (1,900 m³/d).
