OceanGuard® Ballast Water Management System adopts dual mechanisms of filtering and
electro-catalysis to filter and kill the organism in water. EUT Unit is the key part of the system.
The technology is also called Advanced Electro-Catalysis Oxidation Processes (AEOP),
which is environment-friendly, non-toxic and harmless. The system can produce hydroxyl
radicals to highly efficiently kill the micro-organism of ship’s ballast water. Active substances
themselves can break down quickly into unharmful substances without residues,

General Requirements
Filter
Keep some maintenance space left above the filter and equip necessary lifting equipment in
order to maintain the filter element easily. In case to maintain the Filter, piping of something of
the Filter top to be removed temporarily
Cleaning Pump
Keep 150mm space around cleaning pump to guarantee there is enough air around cooling
fan of motor.
Motor is forbidden to hang upside down when pump is installed.
Back-Flushing Pump
It’s better to install the back-flushing pump just after the filter back flushing outlet.
EUT Unit
EUT unit can be installed horizontally and vertically. The subject vessel adopts which
method, and shipyard is responsible for the installation operation.
EUT Power Unit
Cable length between EUT Unit and EUT power supply should not be longer than 60m,
otherwise shipyard need to confirm with manufacturer.
Monitoring Unit
Distance between Monitoring Unit and sampling port need to meet requirements in PI&D
drawing.
Do not install the system close to the outer surface of oil tank (oil container), water tank
(water container), double bottom, etc. (If it has to, 50mm must be left between the system and
such kind of bulkhead surfaces, and add enhanced recovery board. However, resister, heater
and other electric equipment which generate high temperature in the process of work cannot
be installed.
Material of sampling pipe cannot be copper
Neutralization Unit
Neutralization Unit is an important equipment of OceanGuard® Ballast Water Management
System. If the TRO in the tank exceeds 0.1mg/l when the system discharges ballast water, the
Control Unit automatically starts the Neutralization Unit and automatically add certain amount
of neutralizer (sodium thiosulfate solution) into the pipes. The amount of the neutralizer is
automatically pumped by the metering pump in the neutralization unit to keep the TRO in the
water from the system lower than 0.1mg/l.
Flow Meter
Length of Straight Pipe should meet the requirements
Direction of Upper Monitor can be changed according to installation requirements.
Sampling Unit
There need to be enough space for maintenance and sampling.
If there are several discharge lines, it might be necessary with a Sampling Unit on each.
Filter Control Box
Do not install the system close to the outer surface of oil tank (oil container), water tank
(water container), double bottom, etc. (If it has to, 50mm must be left between the system and
such kind of bulkhead surfaces, and add enhanced recovery board. However, resister, heater
and other electric equipment which generate high temperature in the process of work cannot
be installed.
Best installation position is far from places of the heat source and strong vibration.
