Evac introduces ORCA III, the small footprint physicochemical wastewater treatment unit

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).
"With the ORCA III now in production, Evac
offers the whole range of advanced wastewater treatment systems for the
marine industry," says Mika Karjalainen, General Manager of Evac Oy.
"Its predecessor, the ORCA II unit, has been installed over the years
on several hundred vessels, and it complements our MBR biological
membrane wastewater treatment units, also installed on several hundred
vessels to date, which also fulfils the MEPC 159(55) requirements."
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.
