Pre-screening
The separator is not designed to handle heavy solids. A Y-strainer or other suitable pre-
screening filter needs to be installed by the customer in front of the separator to keep larger
particles out of the system
.
A 5 micron sediment filter is included in the system to handle
some turbidity and to protect the oil/emulsion filters.

MAINTENANCE
The system does not have installed redundancy. The general maintenance philosophy for most
of the components is to replace the components as they fail. We have not developed a mean time
between failure for most of the components because every situation is different. The system
does not generally run continuously—only when the bilge level increases to a designated level.
In general, there is adequate time to make any required repair without impacting the bilge water
level. We recommend maintaining critical spare parts in inventory so that if there is a failure the
part can be replaced quickly. Every component can be changed within a few minutes.
Components are fairly inexpensive and it is less expensive to replace the entire component than
it is to buy the part and overhaul the component. The only exception to this is the oil content
monitor, which is the most expensive component on the system. In the case of the oil content
monitor, it is against IMO regulations for the customer to do any maintenance on the system
other than cleaning the cell. If the monitor fails it generally has to replaced. Any attempt by the
customer to break the seal and open the monitor will void the validity of the monitor.
There are some routine maintenance functions that need to be performed to keep the system
running at peak performance:
3.1.
Component Maintenance
3.1.1.
Valve—The solenoid valve can be cleaned if it gets dirt in it. If the valve fails, it will need
to be replaced with a new valve, it cannot be repaired..
3.1.2.
OCM—The OCM will need a periodic check of zero against clean water, and frequent
cleaning of the glass sample cell. The OCM measuring cell has a life of 5 years. At the
end of that period the measuring cell will need to be replaced.
3.1.3.
Filters— The filters will need to be replaced when they become spent.
3.1.4.
Controls components—The controls are minimal. Any maintenance can be done when the
component fails.
3.1.5.
Pump—The pump is a diaphragm pump. You cannot purchase individual components of
the pump, and a repair kit is not available. The pump is rated for continuous duty with a
life expectancy of about 5,000 hours. The pump will self-prime up to 9 feet vertical lift.
