The contract, valued at approximately $5 million, encompasses the installation of Zenon's systems on two more cruise ships.
"A year ago we purchased a Zenon system for the ms Statendam to treat gray and black water for discharge into the environment," said Stein Kruse, Senior Vice President of Fleet Operations. "With the successful results from that ship, we are excited to apply Zenon's system to two additional ships this year."
The ZenoGem membrane bioreactor will process both black and gray water for safe discharge into the environment. Gray water includes water from showers, sinks, galleys and laundry. Black water comes from toilet collection systems onboard ships.
Until recently, gray water discharge has been largely unregulated. Today, the cruise line industry is faced with stringent wastewater discharge regulations on both gray and black water related to sensitive marine environments worldwide.
"In its commitment to maintaining a clean environment of the places it visits, Holland America has demonstrated its corporate responsibility and industry leading stewardship to meet and exceed current regulations," said Kruse.
"Zenon's technology will allow any marine vessel to comply with and beneficially exceed existing discharge regulations," said Andrew Benedek, Zenon's Chairman and Chief Executive Officer. "This contract represents a significant step in the wider adoption of Zenon's technology for the growing cruise ship market globally."
