Cruise vessels equipped with latest wastewater technology

Two vessels to be built by Fincantieri for Princess Cruises will become the latest luxury cruise ships to feature Hamworthy’s Membrane BioReactor (MBR), the technology specifically designed to meet wastewater discharge requirements even in the most sensitive areas.

Both 141,000 gt “Ruby Evolution” class ships (passenger capacity: 3,600) will be fitted with two Hamworthy MBR24 systems each.

With the delivery date for the first vessel due in spring 2013, the first two MBRs will be delivered in August 2011, for installation/commissioning by December 2012. The second vessel is due to be delivered in spring 2014 with equipment delivery in May 2012 and installation/commissioning by December 2013.

Hamworthy’s MBR has been shown to surpass new IMO wastewater discharge regulations by a significant margin: According to the company it achieves suspended solids limits of 3.1mg/l, BOD5 of 2.6mg/l, while faecal coliform is limited to 10.6 cfu per 100m/l. Both residual chlorine levels and pH are also within limits defined for sensitive waters.
