Global cleantech company Evac has received a contract from an undisclosed client to install its integrated waste and wastewater management systems on-board three large-scale cruise vessels of the client, with an option to install on another further vessel.

The first of the three vessels is expected to be delivered in 2018, with the last slated to be delivered by 2021.

Under the €10m deal, the product package to be delivered by Evac is comprised of an Evac Moving Bed Biofilm Reactor (MBBR) wastewater treatment plant.

“The system can be tailored in accordance to site-specific shipboard layouts, ensuring optimum functionality.”

Certified by the International Maritime Organization (IMO) International Convention for the prevention of pollution from ships (MARPOL), Evac’s MBBR delivers environmental capabilities suited to function in environmentally sensitive sea areas (ESSAs) and SPECIAL AREAS (SAs) defined nationally or internationally, where special discharge restrictions apply.

The system can be tailored in accordance to site-specific shipboard layouts, ensuring optimum functionality within the restricted area of the vessel.

It has the ability to treat any blend of marine wastewater streams, including black and grey water streams from accommodation, galley, food reject water, and laundry sources.

The process associated while utilising the technology incurs a low annual chemical consumption rate, which paves the way for a low-cost lifecycle cost solution.

Under the contract, Evac will also provide dry and wet waste treatment systems, including an incinerator and recycling equipment, covering glass, plastic, paper, cardboard and aluminium waste, food waste vacuum systems, a bio sludge treatment unit, plus vacuum collecting systems, including six vacuum units and approximately 2,300 vacuum toilets per vessel.

Last year, among other navy, coast guard, and offshore contracts, Evac was contracted to install its total waste management system on-board the Atlantic Mercy civilian hospital ship.
