Operations
The CS Model is a special
purpose prefabricated inclined plate clarifier
and parallel corrugated plate gravity displacement
type oil/solids/water separators designed to remove
free and dispersed non-emulsifed oil and suspended
solids in heavy solids applications such as in
trucks and heavy equipment pre-wash operations.
Inlet
Compartment
The inlet chamber is
comprised of a non-clog diffuser pipe to distribute
the flow across the width of the CS chamber. The
inlet compartment is made of sufficient volume
to effectively reduce influent suspended solids,
dissipate energy and begin separation. The inclined
plates is elevated on top of the sludge chamber.
As the water moves upwards the suspended particles
have their upwards velocity interrupted by the
inclined plates. These particles drop down and
slide down the inclined plates and join larger
previously settled particles in the sludge hopper.
A sludge compartment is provided to retain sellable
solids.
Separation Chamber
The separation chamber
contains HD Q-PAC Coalescing Plates containing
a minimum of 132 square feet per cubic foot of
effective coalescing area. The plates elements
shall be at 90 degrees to the horizontal or longitudinal
axis of the separator. Spacing between these elements
shall be spaced 3/16" apart for the removal
of a minimum of 99.9% of free droplets of oil
40 micron in size or greater. The elements are
positioned to create an angle of repose of 90
degrees to facilitate the removal of suspended
solids that may tend to build up on the coalescing
surface, which would increase velocities to the
point of discharging an unacceptable effluent.
The Laminar flow with a Reynolds Number of less
than 500 at a maximum design flow rate is maintained
throughout the separator packed bed including
entrance and exit so as to prevent re-entrainment
of oils with water. Flow through the polypropylene
coalescing plates is a crossflow perpendicular
to the vertical plate elements such that all square
feet/cubic foot of coalescing area is available
for contact with rising oil. The plates shall
have a minimum of 87% void volume to facilitate
removal of oil and dirt particles.
Baffles
An oil retention &
underflow weir, and adjustable overflow weir is
provided in the separation chamber. The underflow
weir is positioned to prevent resuspension of
settled solids.
Oil
Skimmer
The clarifier compartment
and the oil separation compartment is provided
with an adjustable rotatable pipe skimmer for
gravity decanting of the separated oil to a product
storage tank.
Clean
Water Chamber
The separator is provided
with a clear water chamber which allows for gravity
or pumped flow through the clean water port.
Covers
The separator is provided
with a vapor tight cover that can easily be removed
for service and maintenance.
