to automatically return non-conforming discharge water back to the sump or bilge. The OCM is
a 15 ppm oil content monitor that has been tested and approved in accordance with IMO
Resolution MEPC.107 (49). The OCM is continually sampling the process stream and is
designed to react quickly to any changes in the oil content.
If there is a requirement for a maximum of 5 ppm oil in the discharge water, the OCM can be
adjusted to only allow discharge with less than 5 ppm oil by following the instructions
referenced in 2.4 below
The pump in the MiniBOSS system is designed to discharge approximately 2 gpm at 20 psig.
Half of the flow is processed through the separator and is either discharged or recycled,
depending on the OCM reading. The other half goes through the OCM and is recycled back to
the bilge. The net flow through the separator is approximately 1 gpm. If the discharge pressure
changes, the flow rate will change according to the pump curve.

OPERATION
The diverter valve(s) are controlled directly by the OCM. The control panel controls the power
to the system and the pump motor control.
Turn on the system disconnect and set the selector switch to the “ON” position. Verify that the
OCM reads zero ppm. If it does not go down to zero in a reasonable period of time you may
need to remove the cap to the OCM cell and use the supplied brush to clean the cell. Then turn
on the system pump to pump oily water through the system. The design flow for the system is
1.0 gpm (.25 M3/hr) at 25 psig back pressure or 1.5 gpm (0.35 m3/hr) for the MiniBOSS-110
