TotlSepRendering1

The HydroFlo TechTotlSep™ (TS) Series fiberglass (FRP) oil/water separator is our top of the line coalescing type gravity separator designed for use in a wide range of applications. The TS series is available in 7 sizes to handle flows up to 125 gpm. Our TS series separators are designed to meet the American Petroleum Institute’s recommendations for oil/water separator design. Features of the TS series include:

  • Integral sludge hopper with two drain ports.
  • Integral oil reservoir with standard fittings suitable for automatic oil pumping level controls.
  • Heavy-duty lid assembly with gaskets and quarter turn latches for a vapor tight seal.

Our TotlSep separators are designed specifically around the data presented in API pub 421 "Design and Operation of Oil/Water Separators". By following all the API design parameters, the HydroFlo enhanced gravity oil/water separators are the most efficient oil water separators available.

We can outfit our separators with various sizes of our proprietary DynaPac™ cross corrugated coalescing media, as well as unlimited varieties of parallel plate media. This allows us to tailor the design of our oil water separator to meet your specific application.

The internal DynaPac™ cross corrugated coalescing media (available in PVC, polypropylene, and stainless steel) can be flushed with water and reused for years of efficient, trouble free use.

One of the advantages of our design is that the recovered product will typically have a residual water content of less than 3%.

TotlSep™ "Enhanced Gravity" type Oil/Water Separator

Model TS-8 handles up to 20 GPM of continuous flow
(based on application)

The TotlSep™ Model TS-8 "coalescing" type oil / water separator is suitable for many different applications and is available in many different configurations. Originally designed for use in the "LUST" remediation market, this separator has proven itself over and over again as a reliable, highly efficient, device.TotlSep1

This unit is available in a hopper bottom configuration for the accumulation and removal of settleable solids. A number of different pump packages are available for the transfer of the separators influent, effluent, sludge or oil.

All TotlSep™ separators come pre-assembled, factory tested and ready to install. They are simple to operate and maintain. The TS series is everything you could want in an industrial duty OWS built to take all the abuse you can throw at it and still keep doing its job day in and day out.

There are many considerations to be taken into account when designing an enhanced gravity oil/water separator. The following needs to be taken into account as a minimum:

1.  Inlet flow distribution

2.  Length to height to width ratios (for proper overall flow distribution)

3.  Cross sectional velocities (actual, not nominal)

4.  Laminar flow conditions

5.  DynaPac™ Cross Corrugated coalescing media or parallel plate media "Reynolds" calculations (for quiescent flow distribution)

6.  Effluent flow distribution

7.  Total projected surface area

These basic design considerations all contribute to the complete utilization of the separation media. Follow them properly and the results will be consistent, equal flow distribution through the separation chamber and the media pack. These are the earmarks of a thoughtful, wholly engineered, fully developed oil/water separator design.

HydroFlo-Flo strives to be the benchmark by which all others are judged. By paying total attention to every detail of the separators design, we can supply you with the finest oil/water separator available anywhere.

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. Performance enhancement shall be achieved by the use of DynaPac™ cross corrugated coalescing media.

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.

  1. Influent Diffusion Chamber
    The flow shall enter the separator submerged, through an influent diffusion chamber. Dispersion across the depth and width of the DYNAPAC™ 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.
  2. Separation Chamber
    The Separation Chamber shall be fitted with DYNAPAC™ cross corrugated coalescing media. Adequate space is to 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.
  3. 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.
  4. Oil Trough
    The oil trough shall be located at the influent end of the separation chamber and incorporate an angled float/oil skimming plate.
  5. Effluent Chamber
    The aqueous phase leaving the DYNAPAC™ 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.
  6. Removable Lids
    The entire separator shall be covered with bolt down removable lid
  7. Coalescing Media
    The coalescing media pack shall be fabricated of oleophilic cross corrugated coalescing media manufactured by HydroFlo Tech.

 

Control Package (Optional):

All HydroFlo Tech 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 a valve is supplied for OSHA LOTO.
