Wärtsilä Hamworthy sewage treatment plants. For marine & offshore applications.

Hamworthy sewage treatment plants (STPs) are a standard in the marine & offshore market. The Hamworthy STP is known to be the most cost-effective and safe answer for processing wastewater at sea. No tempering with our oceans' quality, operating in full compliance with IMO MEPC 227(64) and other stringent guidelines. Each Hamworthy sewage treatment unit is optimised for processing onboard black and grey wastewater streams. The plants are compatible with both conventional gravity and vacuum fed collection systems. They can be operated with salt and freshwater. Each STP is fully automated, allowing for unattended and flexible operation. On-board maintenance requirements are reduced and long-term operating costs are significantly lowered. Hamworthy sewage treatment plants are compact and modular in design, suitable for between-deck installation and adaptable to the customer's new-build specifications.
