Shipboard wastewater treatment system shows promise in meeting strict effluent standards.
A project tested a new wastewater treatment system for ships to see if it could meet strict standards for cleaning sewage and graywater. They used advanced technology with ozone and UV light. The system didn't work well at first with both types of water, but after changes, it could clean sewage water effectively, though not as much at once. More testing is needed for this technology.
