Replacing sewage treatment plant (STP) that have been installed onboard is an expensive and complex operation. This is why shipowners and operators often are surprised by our unique retrofit STP models: the Super Trident® RTC. This retrofit STP is easy to install thanks to only three modular components, each of which fits through standard vessel access ways. No need to cut open the hull of the ship!
Over the last few decades, the RTC line has been widely regarded as a standard retrofit specification by many shipowners worldwide. The Super Trident® retrofit STPs from Wärtsilä Water & Waste offer the most economic and safe answer to disposal of wastewater at sea. On top of that they are fully compliant to IMO MEPC 227(64) effluent quality standards.
