Base Separator Unit
 |
VESSEL
Each vessel is built to exacting standards, sandblasted
and primed with an epoxy primer. The vessels are
then coated with a high grade industrial/marine
Urethane coating to resist the harsh environments. |
 |
BRONZE/RED
BRASS PIPING & FITTINGS
Each and every unit is piped and fitted with corrosion
resistant bronze and red brass pipe & fittings.
Carbon steel pipe is difficult to cover adequately
with paint. In harsh marine environments, any small
opening will begin to rust. Any minor repiping will
likely scar the surface opening opportunities for
corrosion unless touched up. Using only bronze and
red brass valves, fittings and piping provides maximum
corrosion resistance while eliminating the need
for touchup paint work and assuring longer life.
Also with bronze piping the inside of the piping
does not rust. |
 |
CENTRIFUGAL
PUMP
The high quality centrifugal pump we use has a stainless
steel housing, much lower maintenance and longer
life. Also with a centrifugal pump there is no need
for relief valves. |

Construction & Coating Options
Default
The BORS oil/water separation system is normally
constructed of carbon steel, blasted to near white
metal with a 2.5 mil profile and coated with a two-coat
epoxy/urethane coating system for extreme marine
conditions. The vessel is non-coded and is designed
for < 15 psig pressure. Every vessel is hydro-tested
at 45 psig pressure.
An optional coatings
is available
The optional coating system is to follow the blast
with a three-coat system of Zinc then Epoxy then
Urethane.
A final option is a Stainless Steel vessel. |
Mounting Options
 |
Default.
The BORS oil/water separation system uses a solid
three leg system of carbon steel. These legs bolt
down and provide an excellent base that is simple
and easy to clean around. |
 |
Three
options are available for mounting of the vessel.
1- A carbon steel tubular skid system with a primer
and two coats of Epoxy. |
 |
2- A carbon steel full skid system
with a primer and two coats of Epoxy. |
 |
3- A galvanized carbon steel full skid system. |
TPH (Oil in Water) Monitor Options
Default
The base BORS oil/water separation system does not
include a TPH monitor. On models with monitors,
the TPH (Total Petroleum Hydrocarbon) monitor is
used to check the oil content of the discharge water.
These monitors are sometimes referred to as oil
content monitors or oil in water monitors. If the
oil content is not within the established parameters
then the system will recycle the water back to the
source for reprocessing. This assures that no water
is discharged that does not meet the requirement.
This monitor is required to obtain USCG and ABS
certification.
|
Three
different TPH Monitor options are available providing
USCG/ABS certification and/or hazardous area classification.
Two different certifications are available. The
first was required on ships prior to 2005 and monitors
the free oil in the water only. This certification
falls under a regulation known as MEPC 60(33). New
installations on ships in 2005 and beyond are required
to have MEPC 107(49) certification. To obtain this
certification the TPH (Oil in Water) monitor is
a completely different unit that now checks not
only free oil in the water, but also a special emulsion
known as fluid "C". Systems that comply
with this regulation remove the emulsified oil as
well as the free oil. In order to remove Fluid C
to 15 ppm a separate oleophilic filter is required.
BORS systems are available that meet all of these
certifications.
|
The
third monitor option comes into play when the separator
is installed in a Class I Division II or Class I
Division I hazardous area. In these cases the entire
electrical system must be encased to prevent potential
explosions. In this case a different, TPH monitor
option is used. The BORS unit can be configured
to meet these requirements as well.
|
Three
options for TPH Monitors (Oil in Water).
1- Monitor for system to meet MEPC 60(33) regulation.
2- Monitor for system to meet MEPC 107(49) regulation.
3- Monitor for system to meet Class I Division II
or Class I Division I Hazardous area. |
Electrical
Options
Default
The BORS oil/water separation system is normally
supplied with 480/460/440 volt 3 phase power. The
pump motor will run on either 60 cycle or 50 cycle
power, although the motor horsepower potentially
has to be increased in 50 cycle applications to
account for the de-rating of the motor. |
|
Other
options are avaiable as follows.
1- 380/360/340 Volt 3 phase.
2- 240/230/220 Volt 3 phase.
3- 240/230/220 Volt single phase.
4- 120/110 single phase
5- 24 Volt DC
6- 12 Volt DC |
Level
Switch Options
Either a capacitance or a conductance
level switch can be supplied to meet the specific
needs of the customer.
Default
The standard on the BORS unit uses a conductance
type level switch.
Other option is:
Capacitance type level switch.
|
 |
Conductance
Level Measurement Principle:
High frequency sound waves are transmitted across
a transducer gap in the presence of a liquid medium,
but are attenuated when the gap is dry. |
 |
Capacitance
Level Measurement Principle:
As media rises and falls in the tank, the amount
of capacitance developed between the probe and the
ground reference rises and falls. This change in
capacitance is compared to the adjustable set point
and changes the state of a relay when they are equal. |
Control
Panel Options
 |
Default
The BORS oil/water separation system is supplied
standard with a NEMA 4X polycarbonite panel.
These cabinets, are made from high impact resistant
polycarbonate material, and will withstand harsh
industrial environments. They have ready mounted
hinges and quick lock screws. Protection to IP65
is maintained when fastened.
Other options
are available as follows
1- Class I Division II (Polycarbonite).
2- Class I Division II (Stainless).
3- NEMA 7 Control Panel

Oil
Discharge Options
Explanation
The system is designed so that the water pressure
used to fill the system pushes the oil out the top
of the separator and no pump is required. The pressure
needed to push the oil out will vary from 15 psig
to XX depending on the where the oil has to go.
The oil is discharged only during the separator
fill mode. During normal operation a positive seal
is required on the oil discharge line so that the
oil or air cannot come back into the system or reduce
the system vacuum. If the system is pulling the
oily water from a sump that has a negative suction
head then a check valve can be used to provide the
seal. A Y-strainer is used to make sure nothing
can plug up the check valve. If the system has a
positive suction head then the check valve will
allow oil to escape inappropriately. Therefore,
if the system has a positive suction head a check
valve cannot be used. The check valve is the default
for all the economy models plus the 2 and 5 gpm
systems.
The most reliable system is to use a motorized
ball valve on the oil discharge line. This is
a no-fail system and provides the highest degree
of reliability for the oil discharge. This is
the default for the 10, 25 and 45 systems (other
than the economy versions).
If the discharge head is greater than the inlet
fill water pressure an oil pump will be required
to discharge the oil from the separator. The default
pump is a gear pump.
|
Default |
A Y-strainer and check valve is the default for
the 2 and 5 gpm models and all the economy models.
Optional for all other models that have a negative
suction head.
A motorized valve is the default for the 10, 25
and 45 models. Optional for all other models and
required for any system that has a positive suction
head.
The four options available
for oil discharge
1- A Y-strainer and check valve.
(Only works with a negative suction head).
2- A motorized valve. (Default
for the 10, 25 and 45 models. Optional for all other
models and required for any system that has a positive
suction head).
3- A pressurized oil pump (separate
and loose for customer installation).
4- An integrated pressurized oil
pump (mounted on system). |
Motorized
|
Pre-Filter
Options
 |
Default
Three different options are available for a pre-filter
system to prevent larger particulate from entering
the system. The BORS oil/water separation system
is supplied standard with a pre-filter in the form
of a Y-Strainer. This prevents any large material
from entering the separation system.
Other
options are available as follows
1- Basket Strainer.
2- Bag Filter.
3- Hydro Cyclone (Solids Removal) |
Post
Filter Options
Separator with integrated Post-Filter System |
Default
The standard BORS oil/water separation system is
supplied without any post filtration. While this
is adequate in most situations, a post-filter can
be useful in further cleaning the discharge water.
Post filter can remove turbidity, emulsified oil,
and other contaminants not removed by the coalesing
separator.
Filters can be provided separate from the separator
or integrated on a skid. Many filter options are
available on the market with various specific
purposes. Any of these filters can be added to
the discharge stream of the separator.
Our engineers will be happy to assist in the proper
sizing of post filters dependent on the water
flow and content.
Post filter options
include the following either as separate items
or integrated on system.
1- Sand Filter
2- Activated Carbon Filter
3- OrganoClay Filter
4- Any combination of the above in separate or
same tank. |
 |
For MEPC 107(49)
certification a special post-filter separator
is required.
To the left is an illustrated example of an IMO
MEPC 107(49) Certified Separator
with an integrated post-filter system. |
