The Queen Mary II is one of the largest and fastest passenger ships ever built. The vessel is equipped with cutting-edge technology from the mast to the keel. This luxury liner produces enough electricity for a large city and has its own on-board wastewater treatment facility.
New legislation for environmental standards in relation to waste treatment on board vessels meant that an upgrade of their facilities was necessary.
The new process required the installation of a sludge cake handling system to be fitted within a limited space which was capable of metering approximately 20%ds dewatered sludge from a centrifuge into a sludge dryer process to increase the dry solids content prior to being incinerated to maximize energy production.
KEY FACTS
SEEPEX pumps were installed in the ship’s new, modernized facilities which process waste in an environmentally friendly fashion, turning it into energy.
Special BTI range pumps which have the ability to handle highly viscous non-flowable products, as well as being able to accurately meter the product, were fitted with variable speed drives and installed on space-saving, easy-maintenance pump skids.
Centrifuges dewater the sludge to approx. 20% dry solids, which is then metered with SEEPEX pumps into a thermal dryer. To optimize the dryer efficiency, it is important that the correct feeding technology is selected to ensure that the right amount of dry solids is fed into the dryer for optimal efficiency.
KEY SPECIFICATIONS
The technology installed within the new wastewater treatment process enabled compliance with the new environmental standards by burning the accumulated waste in a high-temperature incinerator and then reusing the heat generated within the ship's energy cycle.
The technical solution delivered by SEEPEX results in cost savings for the customer due to reduced disposal costs and assists their energy production. SEEPEX experts were aware of the limited space on board and created a compact design for the sludge cake handling system that fitted perfectly in the available space.
