Oil Water Separators

Our expertise in the design, engineering and application of oil water separation in unmatched.  Our staff has practical experience in this area of wastewater treatment going back to the 1970's.  Over the years, others have tried to unsuccessfully duplicate our separators.  They may manufacture a device that looks like a Hydro-Flo oil water separator, they never acquired all the required design and application experience.  A little bit of knowledge is a dangerous thing and it reflects in their overall approach to oil water separator design.

DynaPac Enhanced Gravity "coalescing" Oil Water SeparatorHydro-Flo's lineup of oil water separators is the most diverse in the marketplace.  Our standard systems are available for treating flow rates of a little as 5 GPM to as much as 3,000 GPM and more.

Also, our separators are designed and manufactured to the highest standards available today and will perform better than any other separation system manufactured anywhere.

Our oil water separators are modular in construction allowing you to add additional features like sludge augers, surface drag skimmers and even dissolved air recirculation systems.  Hydro-Flo oil water separators allow you to alter their configuration in order to meet changing in house and MSD regulations.


Hydro-Flo offers more configurations of inclined plate clarifiers (lamella clarifier) than any other clarifier manufacturer.  The length of the lamella plate packs in our ClariMax line of clarifiers are available from 4' to 12" long with plate spacing anywhere from 3/4" to more than 3".

ClariMax Inclined Plate Clarifier "section"Do you need a clarifier sized for a specific application?  Do you need to replace outdated or dilapidated equipment?  Are you looking for a supplier who can supply equipment meeting a competitive specification?  Come to Hydro-Flo.  Our designers and engineers can  configure our clarifier to meet any site specific requirement.

"Hydro-Flo products are the BEST.  We have been operating Hydro-Flo packaged systems side by side with other systems for over 15 years and Hydro-Flo beats the competition on all levels.

We can process 30% more wastewater through the Hydro-Flo systems, producing better quality, at a lower operating and (substantially lower) maintenance cost than the other systems."

Replacement Media Packs

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.

DynaPac Cross Corrugated "Coalescing" Oil Water Separator MediaSized 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.

Dissolved Air Flotation Systems

Hydro-Flo has been manufacturing dissolved air flotation systems (DAF's) for over 20 years.  We have the expertise to design and specify a system specifically around your site specific requirements

Chemical Reaction Systems

Whether you need a batch or continuous flow chemical reaction system, Hydro-Flo has the expertise required to solve any chemical treatment issue.

Our systems are designed for optimum treatment at the lowest possible chemical consumption.  Designed and built to last, our systems basic configuration can be altered to handle today's requirements as well as changing requirements in the future.

pH Neutralization, Chemical Reaction System

Our packed chemical reaction systems are fully engineered. Your only requirement is to plump the system in line and bring power to the pre-packed skid.

Media Filters

High rate sand filters, deep bed sand filters and multimedia filters (as well as custom configurations) are available.  All Hydro-Flo media filters are designed and built using readily available valves, controls and internal components.  No specially fabricated proprietary developed valves and internals are used.

Multimedia "sand" filter system

What that means to you, the customer, is that when maintenance is required on your sand filter or multimedia system, replacement parts will be readily available from a number of different suppliers (not just the original manufacturer at higher than typical mark-ups).  This is just one of the reasons that our filters are the least expensive to operate and maintain over the life of the equipment.

Custom Pump Systems

Until recently, these pump packages were only available with our packaged water treatment systems.  Quality construction and thoughtful design have always been a Hydro-Flo trademark.

Pre-Packaged Pump Skids And Pump Systems

Over the years we have packaged hundreds of custom pump systems, each with their own fluid transfer issues.  Our pump systems are designed to satisfy your specific application and are built to deliver the longest service life with the lowest associated maintenance costs.

"I find the design information available on the Hydro-Flo site very helpful, especially the sizing spreadsheets.  If I am specifying a system that requires a clarifier, oil water separator, dissolved air flotation system, etc... I always run the data through one of their spreadsheets.  I have found them to be very easy to use and extremely accurate.  The results have always been spot on."

Custom Control Panels

Custom Control PanelOver the past year we have received numerous calls from existing customers asking about custom control systems.  As with our pump systems, until recently, our custom control packages were only available as a part of a packaged water treatment system.

We are a world-class, full service control system design, integration and process system manufacturer.  With over 20 years experience with automated systems, Hydro-Flo has the expertise to solve even your most complex controls issues.

"We have been using Hydro-Flo separators on our offshore drilling rigs with excellent results.  Their application engineers always review our project requirements making sure that the equipment we order is going to perform up to our expectations."
