What Suparator® is

Detail of the Suparator® construction.A simple, passive, construction! No controls, no instruments, no moving parts. Just making the laws of physics work for you. That's all, but it means everything in the separation of oil from water.

The Suparator® principle is a patented solution for the removal of floating substances, like oil, from water or other aqueous media. Initially developed for oil spill recovery applications, the principle has shown to be incomparably effective in any oil/water separation application.



The advantages of the Suparator® unit.

Different from any other oil separation technology, Suparator® actively collects, concentrates and actually removes oil from the process. This 3-step mechanism, collect - concentrate - separate, offers significant advantages.

  • The oil is separated without water which means it is not a chemical waste and has a certain value. It can for instance be used as a fuel in incineration furnaces.
  • Because the separation starts when the concentration of oil is still very low, the oil concentration in the process will no longer rise to unacceptable levels and the life time of the cleaner or coolant is extended to the maximum.
  • The oil is removed very quickly, minimizing the contact time between pollution (oil) and chemistry, and avoiding different oils from mixing. That eliminates undesirable reactions between different oils and between oils and chemistry, which makes a very big difference for the life time of the medium (cleaner, coolant etc.)
  • Because the oil is removed quickly, dirt and fine particles in the oil can not settle out in the process and are removed with the oil. Fine particles, which otherwise would remain suspended in the medium, are removed from the process with the oil.

The Suparator® principle.

The Suparator® principle.The key to the Suparator® technology is the patented principle. Unique about this principle is the three-step separation mechanism; collect -- concentrate -- separate. This enables separating even the smallest traces of oil, without a drop of water, in the shortest possible time. All with a simple, passive construction.

The sketch shows a channel in cross-sectional view. The aqueous medium (blue), with oil (red), flows through this channel from left to right. A number of plates are mounted across the channel, such that the major part of the flow passes underneath (under flow) and a smaller portion passes overhead (upper flow).

  1. The upper flow passes overhead and carries along the traces of oil.
  2. Oil and oil traces are collected in the first compartment. Through the opening at the bottom, aqueous medium is sucked out from this compartment.
  3. Oil is being concentrated into a floating layer of considerable thickness. Water and chemicals separate from the oil, into the aqueous phase.
  4. The upper fraction of the oil layer runs off over the weir: pure oil is being separated.

What it looks like in practice.

An 86 unit in use.The photo to the right shows an 86 unit in use, viewed from effluent side.

  1. The upper flow passes overhead and carries along the (traces of) oil into the first compartment; oil starts to show up.
  2. The traces of oil are further collected and concentrated and start to build an oil film.
  3. The oil is concentrated into a, thick, floating layer. Water and chemicals separate from this layer into the aqueous phase below it.
  4. The upper fraction of the oil layer runs off over the weir: pure oil is being separated.
  5. The clean aqueous medium runs off and is returned to the process.

This picture very clearly shows while there is no visible oil in the front of the Suparator® unit, the oil starts showing up more and more as the medium passes through the patented Suparator® construction.

Extended use of the Suparator® principle.

Oil, grease, solids, chemicals, and what other substances found in the process, interact to form floating substances that are far from the nice, fluid, substance we think of when we say oil. A common way to deal with this is to regularly clean the installation: not just the oil separator but the washer, the cleaning bath, the pit or what ever. For Suparator® there is a more intelligent way to deal with this!

To help remove the non-oil substances, and to minimize operational and maintenance cost, a number of extensions have been developed for Suparator®. These include:

Flush headers.

Flush headers are used to wash away the material that would otherwise accumulate and cause a Suparator® unit to need cleaning. Typically flushing is done during normal operation, using small amounts of fresh water. Flush headers, mounted in crucial areas in a system "stir up" any accumulated material and cause it to be carried off with the flow. Flushing can easily be automated, practically eliminating the need for cleaning the unit.

The rake skimmer.

Some floating matter tends to build up and will not go over the oil weir. As a result it builds up in time and inhibits liquid oil from being separated as well. Manually removing the accumulated material at given times is a solution, but may not be very practical. A rake skimmer is the intelligent way to address the problem.

The rake skimmer sweeps the surface in such a way that material that otherwise would accumulate, and which would not go over the valve tops or the oil weir, is pushed towards and over the oil weir. A single rake, moving slowly and wiping the surface at the Suparator® construction does all the work.

The Suparskim® principle

Fixed Suparskim® skimmer.Suparskim® skimmers are designed to take off the top layer from the medium in a tank, bath or pit. They are not an oil separation device by themselves but are an essential component in the Skim & Treat method. Suparskim® skimmers come in fixed-mounted and floating versions to accommodate for any level variation.

The purpose of the Suparskim® skimmer.

The variety in oil/water separation applications is enormous. Not only in the nature of the oil/water mixture, but also in the variations in shape, size and dimensions of the installations the mixture is to be found or treated. Washers, cleaning baths, coolant sumps, API separators, sewer systems etc..

To connect to this variety of installations in the right way, flexibility is a key issue. Suparskim® provides this flexibility. Typically one of the many Suparskim® models is mounted inside the tank, bath, pit or other and takes out the oil/water mixture for further processing.

Suparskim® skimmers support optimal separation performance and eliminate problems with floating layers from oil, grease or other light substances. By continuously removing the top layer from a bath or tank, and separating the oil from this fluid, an optimal result is achieved. Floating layers can no longer be formed; Suparskim® skimmers don't even leave an oil film behind!


The Suparskim® principle.

The Suparskim® principle.Suparskim® skimmers make use of a simple and reliable principle.

  1. The Suparskim® skimmer is installed in the tank with the aqueous medium.
  2. If the level rises above the nose of the skimmer, the medium will flow into the skimmer trough.......
  3. ...... causing the level inside the trough to rise
  4. The rising level will cause the trough to tilt backwards, reducing the incoming flow.
  5. The medium inside the skimmer trough is taken out, either by gravity of with a pump, ........
  6. ...... causing the level inside the trough to drop.
  7. The dropping level will cause the skimmer trough to tilt forward, increasing the incoming flow.

The effect of this mechanism is that the skimmer will find a steady position where the flow into the trough equals the flow taken out. Only fluctuation in the level or in the flow out ot the trough will cause the skimmer to change its position. As long as the level is within the range of the skimmer, the surface layer from the tank or bath will run off into the skimmer trough.


Fixed Suparskim® skimmers.

In the above sketches, the Suparskim® skimmer is mounted in a tank at a fixed height. It will follow the liquid level as long as it is within the range of the skimmer, indicated by the dotted lines. For fixed skimmers the maximum level variation that currently can be handled is 160mm. If the level variation is more than 160mm, a floating Suparskim® skimmer must be used.

Floating Suparskim® skimmers.

Floating Suparskim® skimmer.For level variations beyond 160 mm, floating type Suparskim® skimmers are used. Floating Suparskim® skimmer have the same tilting skimming trough with one or more floats connected to it. A floating Suparskim® skimmer is connected to a coupling in the wall, or a rigid pipe running into the tank, with a flexible hose. The maximum level variation possible with a floating Suparskim® skimmer is determined by the length of the flexible hose.

Suparator® features

suparator-different-tnOil separation done differently.

Different from any other oil separator, a Suparator® system has a special construction built in which collects and concentrates the oil before separation. This brings many advantages, resulting in a much more efficient separation and significant savings.

Gravity separators primarily collect the oil; they build an oil layer inside the separator, resulting in long contact times. Suparator® uses gravity separation but adds its three step separation mechanism which causes the oil separation to start early on, the separated oil to be free from water and the contact time being very short.

Three step separation.

Suparator® utilizes a three-step separation process: collect, concentrate, separate. The special construction collects any amount of oil, even the smallest traces. The traces are than concentrated, causing water and chemicals to separate from it, and build an oil layer. Finally the oil is separated without water and all within minutes.

Early start of the separation.

Because Suparator® collects and concentrates even traces of oil, it starts removing when the oil concentration is still very low. That means the oil concentration in a process will no longer reach a level where it can have a negative effect on the whole process. The oil problem is eliminated.

Separation without water.

Conventional oil separators and skimmers require a thick layer of oil to function properly, but that means long contact times and accumulation of dirt. So it is necessary to keep the oil layer as thin as possible, but than you get a lot of water being separated with the oil. You want neither one nor the other. Because Suparator® can collect and concentrate even traces of oil, it does not rely on thick oil layers to function properly and will separate oil without water.

Short contact time.

"Oil" is not oil; "water" is not water. In oil/water separation, "oil" typically is a mixture of substances, plus it contains dirt and other pollutants. "Water" always contains soluble substances, either as pollutions from the process or intentionally added, as in aqueous cleaners or machine coolants. The longer the contact time, the more all these substances start to interact. Add bacteria growth to that and what you get is a nasty mixture which, at best, can only partially be separated. The shorter the contact time, the cleaner the process, the better the oil control.

Economical solution.

Simple and effective oil separation.Suparator® is a unique technology, developed for the separation of oil from aqueous media. It adds valuable performance to conventional oil separation without adding cost. With a simple, reliable, construction oil traces are separated continously, returning fresh, clean medium back to the process.

Different from all other oil separation devices, Suparator® actively removes the oil and puts it in the drum. Its three-step separation process removes oil, without water, from the process at an early stage, warranting extremely short contact times. It adds ´oil control´ to your process, eliminating the cost that result from oil contamination.

The heart of the system is a simple, passive construction, that requires no maintenance, no controls and no energy. Suparator® systems do not use any consumables and separate the oil only.

Investments in Suparator® oil control systems have a very short pay-back time, not only because of the minimal maintenance and operational cost, but even more so because of the significant savings.


Cost saving.

Separationg pure oil eliminates disposal cost.Oil/water separation is about "water", not about oil. The aqueous medium must be cleaned from oil in order to make better use of it; reuse of water or extended lifetime for cleaners, coolants etc. Suparator® offers you real time control of the oil level in your aqueous medium, your coolant or cleaner. Oil control leads to longer life times, to process control and to quality control. Longer lifetimes mean less cost for make-up and less cost for disposal.

Clean cut separation

Suparator® does not separate water or chemicals. With water concentrations of less than 1% the disposal cost for oily waste are eliminated; the recovered oil has value and will be collected at no cost.

A passive construction.

All it takes is the unique, passive, construction. No maintenance sensitive devices, no controls, no energy.

No consumables. Suparator® uses no consumables, like absorbents, coalescing media, absorbing filter bags etc., which means no cost for the consumables themselves and no cost for disposal of spent consumables.
