Wärtsilä pollution prevention for ‘QM2’

Cunard’s 2,620 passenger capacity Queen Mary 2 entered service in 2004 and was designed with the aim of reducing the vessel’s impact on the environment through more efficient waste management. With the existing on-board system now due for replacement, Wärtsilä will install two Wärtsilä Hamworthy Membrane BioReactor (MBR) 16 systems to maintain the ship’s high environmental standards.

“Environmental performance is of ever increasing importance throughout the marine industry, but especially so for cruise ships and ferries,” said Juha Kytölä, vice president, environmental solutions, Wärtsilä.

The Wärtsilä Hamworthy MBR solution is designed to help with the management of both ‘grey’ and ‘black’ wastewater, and to monitor discharges to the sea.

Based on biological degradation and membrane separation, Wärtsilä say it delivers high quality discharge without the need for any addition or generation of chemicals hazardous to the maritime or shipboard environments.
