Highland's
Patented Design:
Highland Tank's patented design combines
state-of-the art technology with time-tested
materials, making Highland separators the
strongest and most reliable high-performance
separators in the industry.
The
oil/water separator is a stationary underground,
wastewater treatment vessel, filled with
water. Internal baffles and coalascers accelerate
the oil/water separation process. Waste
accumulates within the separator while effluent
is discharged by gravity. The system is
designed for access from above for observation,
maintenance and cleaning.

Diffusion
Baffle:
The velocity head diffusion baffle, located
near the inlet of the separator, is designed
to serve four basic functions:
1. To dissipate the velocity head, thereby improving
the overall hydraulic characteristics of the
separator.
2. To direct incoming flow downward and outward
maximizing the use of the separator volume.
3. To reduce flow turbulence and to distribute
the flow evenly over the separator's cross-sectional
area.
4. To isolate inlet turbulence from the rest
of the separator. |

Internal
Chambers:
In the sediment chamber, heavy solids settle
out, and concentrated oil slugs rise to the
surface. As the oily water passes through the
parallel corrugated plate coalescer (an inclined
arrangement of parallel corrugated plates) the
oil rises and coalesces into sheets on the underside
of each plate. The oil then creeps up the plate
surface, and breaks loose at the top in the
form of large globules. These globules then
rise rapidly to the surface of the separation
chamber where the separated oil accumulates.
The
effluent flows downward to the outlet downcomer,
where it is discharged by gravity displacement
from the lower regions of the separator.

Petro-Screen:
For enhanced oil removal efficiency, a "Petro-Screen"
polypropylene coalescer (a bundle of oleophilic
[oil attracting] fibers, layered from coarse
to fine and encased within a solid framework)
is used to intercept droplets of oil too minute
to be removed by the parallel corrugated plate
coalescer.

Monitoring
Systems:
For easy and efficient operation and maintenance,
an oil level sensor can sound an alarm at high
oil levels so waste oil can be removed from
the separator. Double-wall separators can be
furnished with a leak detection system for the
interstitial space.
Additional
monitoring equipment is available for oil
or water level sensing, alarm and pumpout
control.
