The OMNIPURE Series 64 marine sewage treatment system from De Nora is compliant with International Maritime Organization standards and ranges in treatment capacities up to 13,200 gpd in a single system. Units can be combined for increased capacity. The system uses a catalytic coating technology to ensure a smaller footprint and minimized maintenance. The electrolytic processes in the system impose physical and chemical changes to the wastewater stream as it passes through, resulting in effluent quality below the required specifications. 215/997-4000; www.denora.com
