Evac introduces ORCA III

Evac, the leading supplier of advanced wastewater collection and treatment solutions introduces the ORCA III small footprint physicochemical advanced wastewater treatment unit.
The ORCA III is the ideal wastewater treatment 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 automated operation.

The ORCA III comes in six different sizes, with a hydraulic loading capacity ranging from 20cu.m./day down to 1.5cu.m./day. It is ideally suited for efficient wastewater treatment for vessels which stay idle part of the time, thanks to its physicochemical treatment technology. The system meets the requirements of MEPC 159(55) of the International Maritime Organization (IMO).

In the ORCA III wastewater treatment system the sewage from the holding tank for black and grey water is transferred, using a macerator pump, to a sedimentation tank through a static mixer and flocculation dosing. In a separate second tank section the clarified liquid is re-circulated through a disc filter and the organic matter is oxidised with Hypochlorite, after which the clean wastewater is discharged overboard.

Being fully automatic the ORCA III is safe and easy to operate and maintain. The operation costs are low. The complete package includes also the transfer/macerator pump.

Evac is a global market leader regarding the contracted number of advanced onboard wastewater process systems. In addition to the ORCA III family of physicochemical wastewater treatment units the company produces also its MBR biological membrane-based advanced wastewater treatment system. The company is also the market leader in onboard vacuum toilet technology for the marine industry.

For the Mega Yacht market several new products are currently being introduced, including a new small capacity Evac E16 vacuum pump. The smaller capacity units of the ORCA III also fit perfectly into this segment, thanks to its compact design and automatic operation
