Equipment Criteria:
The separator shall be a specially fabricated rectangular channel
tank. The separation process shall be fully automatic requiring no
moving parts. The design of the separator shall satisfy the
requirements of API PUBLICATION 421, Feb. 1990 on DESIGN & OPERATION
OF OIL/WATER SEPARATORS and Stokes' law.
Separation Cell:
The separation cell is designed using elements of American Petroleum
Institute's publication 421, Feb. 1990, “Design of Oil-Water
Separators” to ensure the best possible use of particle rise rate
performance. The separation cell is a rectangular “V” bottom tank
manufactured from carbon steel with an effluent surface baffle, 304
stainless steel, full width, adjustable overflow weir, effluent
collection chamber with flanged outlet nozzle and recycle suction
port, and angled float beaching plate.
- Influent Diffusion Chamber
The flow shall enter the separator submerged, through an
influent diffusion chamber. Dispersion across the depth and
width of the DYNA-PAK is to be achieved through the use of a
non-clog diffuser. Heavy solids that fall out of suspension
here shall be channeled to the sludge collection chamber.
- Separation Chamber
The Separation Chamber shall be fitted with DYNA-PAK cross
corrugated coalescing media. Adequate space will be left
before and after the chamber to prevent short circuiting through
the pack. A total of ____ cubic feet of coalescing media is
provided with ½, ¾, or 1-1/4” spacing providing _______ft3 of
coalescing surface area.
- Sludge Collection Chamber
The sludge collection chamber shall be located directly beneath
the coalescing media pack and provide ample storage capacity for
the settled sludge. The sides of the chamber shall be sloped at
45 degrees to insure easy and complete removal of the settled
sludge.
- Oil Trough
The oil trough shall be located at the influent end of the
separation chamber and incorporate an angled float/oil skimming
plate.
- Effluent Chamber
The aqueous phase leaving the DYNA-PAK shall pass under the oil
retention baffle and up over the adjustable 304 stainless steel
effluent weir, which shall maintain the liquid level throughout
the separator.
- Removable Lids
The entire separator shall be covered with bolt down removable
lid
Surface Skimmer (Optional):
Provide a removable float skimming system with frame assembly and
drive motor, sprockets, chains and full width stainless steel
skimming blades. The skimmer blades are mounted on swivel pins that
are fastened to the skimmer chains and maintain the blades in a down
position at all times. The conveyer chains are provided with drive
sprockets on a full width shaft at the drive end and four
independent idler sprockets at the return end. The skimmer system
frame shall provide a sprocket tension adjustment device and the
carrying and return tracks for the chain. The entire system shall
be self supporting with side and end channels, and cross members
with lifting lugs that permit removal of the skimmer assembly as a
complete unit for easy cleaning and service. The skimmer drive
system is provided with a hollow shaft gear reducer that is
maintenance free.
Bottom Sludge Auger (Optional):
The ribbon flight auger is made from 304 stainless steel, has
converging flights to gently move settled sludge toward the sludge
outlet nozzle and is driven at 3-5 RPM by an industrial duty TEFC
motor with gear box speed reduction.
Operational Criteria
Overflow ratio of _____ GPM/ft2 settling surface area at a flow rate
of ___ GPM.
Maximum allowable wastewater temperature = 1308 F
Control Package (Optional):
All Hydro-Flo Technologies oil/water separation systems are fully automated.
Control packages (depending on your specific requirements) are
available in either basic relay logic controls, or a full state of the art
PLC
with touch screen HMI and our
sophisticated treatment algorithms. The relay logic controls
package allows basic reconfiguration of the original system settings,
while the PLC based package allows maximum flexibility
to change the process parameters, as well as tight control that
minimizes chemical usage. We can include a variety of options
including digital data logging of critical
process parameters, ethernet access to process data, communication
with Building Management Systems, and even remote system access
using cellular wireless technology.
All enclosures are NEMA 4X. Where metallic
enclosures are used, they are provided with epoxy or polyester
finishes for corrosion resistance. All conduit is plastic coated
where possible. Low voltage 24VDC is used throughout to minimize
service personnel exposure to high voltage. All panels are OSHA LOTO
and NFPA 79 compliant. Additionally UL-508 listing is available.
Effluent Monitoring: As mandated by
the local controlling authority, the effluent quality must be
continuously monitored. A two pen recorder is to be used to
monitor effluent flow rate and pH. The recorder is to be
equipped with a flow totalizer. Any effluent pH deviations will
trigger an alarm and system discharge will be halted.
System Packaging:
The system is supplied as a completely
fabricated "turnkey" package. All devices are pre-wired and plumbed.
You need to make the plumbing connections to
and from the system and a single electrical connection point for
incoming power. The disconnect on the MCP provides OSHA Lock
Out / Tag Out and NFPA 79 compliance. For systems requiring
compressed air, only one connection is required and the valve is
supplied for OSHA LOTO.
