Wärtsilä has fitted its advanced wastewater treatment system onboard Cunard Line’s Queen Mary 2, enabling her to meet the latest environmental regulations.

The 2,620-guest ship’s existing onboard wastewater system will be replaced by two Wärtsilä Hamworthy Membrane BioReactor (MBR) 16 systems, which will manage both black and grey wastewater and monitor discharges to the sea.

“Environmental performance is of ever increasing importance throughout the marine industry, but especially so for cruise ships and ferries,” said Juha Kytölä, vice president of Environmental Solutions at Wärtsilä Ship Power. “Wärtsilä’s in-house know-how and broad experience in wastewater treatment and management systems for ships were crucial factors in the award of this important contract.”

Wärtsilä Hamworthy MBR is an advanced wastewater treatment process based on biological degradation and membrane separation and does not require any addition of chemicals that could be hazardous to the maritime or shipboard environments. It will enable Queen Mary 2 to meet both current and future environmental regulations.
