Waste, Oil & Fresh Water Management WÄRTSILÄ HAMWORTHY MEMBRANE BIOREACTOR (MBR) TECHNOLOGY THE ADVANCED, HYGIENIC END TO WASTEWATER AT SEA As environmental regulations continue to evolve, ensuring that your ship’s effluent is clean and safe is a growing priority. Understanding and keeping up with these new, green requirements can be a challenge. Wärtsilä has a proven track-record in developing technology that meets anticipated environmental standards and has set the global benchmark in shipboard wastewater management. The Wärtsilä Hamworthy Membrane BioReactor (MBR) system is advanced, innovative technology which allows for the high purity treatment of black and grey water, satisfying the highest level of marine and offshore standards. The Wärtsilä Hamworthy MBR system is based on biological degradation and membrane separation that allows for the treatment of black and grey water to satisfy the most stringent standards. The process produces the highest quality discharge, without requiring any addition, or generation of, chemicals that are hazardous to the environment or ship operation. Effluent quality tests conducted by the US National Sanitary Foundation, on the Wärtsilä Hamworthy MBR, produced results exceeding the rigorous future legislative pollutant standards envisaged. The technology also achieved outstanding performance in Alaska, under the scrutiny of the local authority, USCG and USEPA studies over the past seasons. The membrane permeate quality exceeds the most demanding coliform standards even without additional UV or chemical disinfection. The latest system optimisation has achieved over 25% savings on energy consumption plus consumables and over 50% reduction in operational man-hours. Satellite communication allows the MBR systems to be remotely monitored by specialists, as part of our fleet support

ULTRAFILTRATION MEMBRANE MODULES MARKET DRIVERS MBR systems utilise a side-stream cross-flow membrane configuration. The membrane module has robust GRP housing perfectly suited for the shipboard environment. The module contains large numbers of ultrafiltration membrane tubes designed to achieve very high permeate production under the cross-flow scouring velocity with minimum risks of any blockage. CUSTOMER BENEFITS: • Meet and exceed the likely regulatory requirements for both new and existing installations. • Maintain a more proactive public image. • Minimisation of size and weight. • Lowest...
