Space is always an issue on river cruise vessels.\u201d<\/p>\n<p>Beavis, a marine engineer, said that using a vessel\u2019s existing tanks as a first stage bioreactor can allow for greater colonies of bacteria to more effectively \u2018eat away at the waste\u2019.<\/p>\n<p>\u201cThis is a much more cost-effective approach to wastewater treatment where space is a limitation, and we can easily adapt the concept to meet the requirements of larger ocean-going cruiseships,\u201d he said. \u201cUse of existing tanks in this way, can reduce system footprint by more than two-thirds, depending on the dimensions of tank, and reduce capital expenditure. However, additional tank venting would be required for safety reasons.\u201d<\/p>\n<p>The European riverboat sector is relatively new market for ACO Marine, with the Maripur NF Mark IV system passing EC Rhine Rules certification tests in 2012.<\/p>\n<p>Directive\u00a02006\/87\/EC regulates the discharge of wastewater in the Mosel, Rhine and Danube rivers and requires more extensive equipment tests than those required for commercial ocean-going vessels.<\/p>\n<p>Stringent certification testing can take up to 40 days as equipment has to be trialled at different electrical loads, typically 50%, 100% and 200%.<\/p>\n<p>ACO Marine is now actively marketing its wastewater treatment technology in the river cruise segment with several contracts nearing the final stage of negotiations.<\/p>\n<p>The Carissima is one of a number of river cruise vessels being retrofitted with ACO Marine\u2019s waste water treatment systems<\/p>\n<p>&nbsp;<\/p>\n<p>www.acomarine.com<\/p>\n","protected":false},"excerpt":{"rendered":"<p>ACO Marine has been awarded contracts to supply its advanced wastewater treatment technology as retrofit solutions to river cruise vessels operating on European waterways.
