A Marine Sanitation Device (MSD) by ACT2 Technologies, of Ft. Lauderdale Florida has been fitted to Transocean's 'Discoverer Enterprise'.
The Discoverer Enterprise is leased to BP and owned by Transocean. ACT2 say that they are also working on additional units for Transocean in the 200 person range.
BP, Transocean, and ACT2 Technologies are committed to reducing sanitation pollution to zero while existing 159(55) regulations still allow many pollutants to be discharged. Factory Acceptance Testing of ACT2 Piranha units show pollutant values at zero, or U (Undetectable) while 159(55) regulations still allow pollutants to have 2 and 3 digit values.
The ACT2 Piranha systems are designed to digest sewage and paper into pure, odorless and colorless water to meet EPA water reuse standards, thus making it more pure than any navigable body of water on the planet. The systems do not use chlorine or other harmful chemicals that are banned in Europe and other Countries around the world. The Piranha systems also meet the more stringent land based Sewage Treatment Plant requirements.
All Piranha units are sludge digesters and do not use corrosive saltwater to dilute the sewage to legal limits before pumping overboard. The systems do not use MBR (Membrane Bio Reactors) that require physical and regular sludge removal and storage, a job that all engineers try to avoid. The Piranha units are also self-cleaning so engineers or crew do not handle or clean, or come in contact with sludge or wastewater.
Optional modules will allow the effluent to exceed EPA drinking water standards should there be a need to generate reuse water for technical purposes such as cleaning, re-flushing, Deepwater drilling, etc, etc.
