Oil Water Separators and Separation Systems

Oil/water separators are designed to separate free and dispersed oils and greases (as well as gross quantities of suspended solids) from wastewater or process streams, making it possible for sensitive downstream equipment to perform as designed.  A properly designed oil/water separator will reduce your overall operating costs and improve overall system maintainability.

DynaPac™                 
"Enhanced Gravity" type Oil/Water Separator

Model DP-2 handles up to
10 GPM of continuous flow
(based on application)

The DynaPac™ Model DP-2 "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.

This unit is available in a flat bottom configuration or with a hopper bottom 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 DynaPac™ separators come pre-assembled, factory tested and ready to install.  They are simple to  operate and maintain.   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.

To meet these goals, Hydro-Flo manufactures three basic types of oil water separators:  "API" type, "Enhanced Gravity" type (often referred to as a "coalescing" oil/water separator) and "Pressure Rated" oil/water separators.  All of these basic separator types are available in numerous models and configurations to meet your specific separation needs.

Oil/water separators are usually the first stage of any wastewater treatment system.  However, in some cases, an oil water separator can be used as effective "end of pipe" treatment equipment.

The most severe applications are typically handled by an API oil/water separator.  Designed around API published studies, they are ideal for treating waste-streams with viscous oils, greases and high total suspended solids loadings.

The most efficient separator is the enhanced gravity oil/water separator.  The separation process is "enhanced" with the installation of several media styles, all of which greatly increase the separator's overall projected surface area.  Many manufacturers refer to this as a "Coalescing" oil/water separator.

Hydro-Flo's pressure rated separators are designed for sophisticated process and wastewater applications.  these heavy duty separators can be configured to separate a gas from a myriad of immiscible liquids and suspended solids or any immiscible liquids and solids of different specific gravity.

They are ideally suited for pressurized process loops where the installation of a non-pressurized gravity system would be impractical.

Hydro-Flo manufactures a broad line of media packs for oil water separators, inclined plate - parallel plate - lamella type clarifiers, biological systems, etc...  We can supply packs for both stand alone fabricated devices or large in ground systems.

Sized to handle any flow rate and designed to handle even the highest product loading ratios.  Hydro-Flo media packs are designed and built to deliver state-of-the-art results and the longest service life achievable.

A wide variety of materials of construction are available to meet even the most demanding applications.

SEPARATOR FOULING ISSUES AT A SUPERFUND SITE

"We have used oil/water separators by other suppliers and were never really happy with the results.  They were often undersized and typically difficult to maintain.

Your application engineers were a great help in solving our iron bacteria (moose) issues.  Your MaxiSep oil water separator has been in operation at our site for over a year and is operating flawlessly without any of the fouling and constant maintenance required of the other separators we had installed at the site.  Thanks for all your help."

"Superfund site", wastewater systems design engineer

There are many misconceptions in the market place concerning the proper design and application of "oil/water separators".  Often, oil/water separators are the most misunderstood "basic" device available in the market today.

Many companies profess to design their separators around API pub 421 "Design and Operation of Oil/Water Separators".  In fact, I think you would be hard pressed to find a supplier who does not claim to design their separators around API 421.  Unfortunately, most of these companies misunderstand much of the data and misinterpret many of the concepts and theories presented in this publication.

We take every aspect of the design of our separators very seriously.  We analyze cross sectional velocities (actual, not nominal), length to height to width ratios (for proper overall flow distribution), laminar flow conditions and Reynolds calculations (for quiescent flow distribution), inlet flow distribution, effluent flow distribution, and every other criteria throughout the entire separator.  Most other suppliers only solve for projected surface area, without consideration to any of the other design parameters.

Hydro-Flo Oil Water Separators are designed to perform exactly as specified, day in and day out, giving you the consistent high quality results your process deserves.
