Evac, the leading supplier of advancedwastewater collection and treatment solutions introduces the ORCA III smallfootprint physicochemical advanced wastewater treatment unit, the company said in a statement.
The ORCA III is the ideal wastewatertreatment system for merchant vessels, navy and patrol vessels, ferries,offshore supply vessels, service vessels and platforms, and for mega-yachts,requiring a compact design, small volume and footprint and fully automatedoperation.
The ORCA III comes in six different sizes,with a hydraulic loading capacity ranging from 20cu.m./day down to1.5cu.m./day. It is ideally suited for efficient wastewater treatment forvessels which stay idle part of the time, thanks to its physicochemicaltreatment technology. The system meets the requirements of MEPC 159(55) of theInternational Maritime Organization (IMO).
"With the ORCA III now in production,Evac offers the whole range of advanced wastewater treatment systems for themarine industry," says Mika Karjalainen, General Manager of Evac Oy."Its predecessor, the ORCA II unit, has been installed over the years onseveral hundred vessels, and it complements our MBR biological membranewastewater treatment units, also installed on several hundred vessels to date,which also fulfils the MEPC 159(55) requirements."
In the ORCA III wastewater treatment systemthe sewage from the holding tank for black and grey water is transferred, usinga macerator pump, to a sedimentation tank through a static mixer andflocculation dosing. In a separate second tank section the clarified liquid isre-circulated through a disc filter and the organic matter is oxidised withHypochlorite, after which the clean wastewater is discharged overboard. Being fully automatic the ORCA III is safeand easy to operate and maintain. The operation costs are low. The completepackage includes also the transfer/macerator pump.
Evac is a global market leader regardingthe contracted number of advanced onboard wastewater process systems. Inaddition to the ORCA III family of physicochemical wastewater treatment unitsthe company produces also its MBR biological membrane-based advanced wastewatertreatment system.
The company is also the market leader inonboard vacuum toilet technology for the marine industry. For the Mega Yachtmarket several new products are currently being introduced, including a newsmall capacity Evac E16 vacuum pump. The smaller capacity units of the ORCA IIIalso fit perfectly into this segment, thanks to its compact design andautomatic operation.
