Global cleantech company Evac has been contracted to install its total waste management system on-board the Atlantic Mercy civilian hospital ship.
The Atlantic Mercy, which is owned and will be operated by the non-profit Mercy Ships, is currently under construction with China Shipbuilding Industry Corporation at the Tianjin Xingang Shipyard.
The ship will be operated to provide medical care in the poorest parts of Africa. It is expected to be delivered in 2016.
Evac marketing and sales Asia senior vice-president Konstantin Tchetchine said: "All these technologies serve to reduce waste, maximise hygiene, and free up space on the ship for use in accomplishing its primary mission.
"Vacuum toilets require only 1.2l of water per flush, six to seven times less than gravity toilets. That means water savings of 52m³ per day for this ship which can carry 950 persons.
"When we flush a toilet we are wasting pure, drinkable water.
"And in Africa, pure water is a very precious commodity."
Evac’s total waste management system will include 393 vacuum toilets, two vacuum units (type Evac OnlineMax 175), two sewage treatment plants (type Evac MBR 135K), one incinerator, a sludge handling system and a food waste vacuum collecting system.
The system also features a converter for medical waste, which is ground at high-temperatures to disinfect it, and a thermal steriliser for hospital wastewater rounds to further reduce contamination risks from the ship’s hospital areas.
