Oil / Water separators (Stormceptor)
Oil / Water separators (Stormceptor)
(OP)
I am currently working on a project involving oil / water seperators such as Stormceptor. I have a large amount of company supplied data, but I can't seem to find any journals or periodicals on the use of similar products. If anyone knows of any, please help me out.

RE: Oil / Water separators (Stormceptor)
There is a lot of interest in Seattle area in these type of treatment BMPs, but still not much perfomance data that is independent of the manufacturers. If you are interested in the actual performance, you should pay attention to the testing protocols used. Some manufacturers create their own "stormwater" by mixing dirt & tap water, so they can then test their products in the lab. This approach is inconclusive since real stormwater is variable in its sediment & pollutant loading. Specifically, the fine sediments loading to a treatment device will vary depending on the soil types, land uses, erosion control measures employed in the basin, etc. Most of the "compact" treatment devices have a very limited capability to remove fine sediments. In the Pacific Northwest, this can be a problem because one of the concerns is fine sediments that can settle and damage fish habitat.
Engineering judgment is required if you are designing a system that will achieve a certain removal effectiveness.

Ultra-Urban Stormwater Treatment Technologies
RE: Oil / Water separators (Stormceptor)
I recently installed one at a Port in the State of Washington. I used the model 5000 with a capacity of 6.5 to 8 CFS with a weir overflow around the unit when flow reaches 6.5 CFS.
The unit is approved by Ecology in Washington.
I do not believe that there is much publised about these units. I do not like the StormCeptor units. The Vortechnics unit is more like an API separator with a sedimentation chamber on the inlet and seems to work better.

I would suggest that you take a look at CDS Technologies. Their website is www.cdstech.com.
CDS units are much more compact and have equivalent treatments to Stormceptor and Vortechnics.
Take care

I have speced and installed 6 Vortechnics and about 20 Stormceptors in NJ and GA and am happy with both products. They are different designs and prices so it all depends on your specific job site/criteria on which one to choose.
The Stormceptor is like a very deep manhole where the Vortechnics is like a box vault. The Vortechnics is great if you have a high water table where the Stormceptor would have instalation problems. On the Stormceptor side, the cost of the product and instalation is usually slightly cheaper than the Vortechnics and most contractors find it easy to install.
Their are other products out their that clean the water, not many can claim 80% TSS removal and those that can, usually don't have any study information to back up the claim. Stormceptor and Vortechnics are the only two that I personally have seen the data on and have speced for my jobs. The site given above by Scully109 has a great amount of data on the products and may be able to help you in your selection.
As a side note, The state of NJ reviewes all project stormwater at the state level and they only accept two products for water quality treatment, Stormceptor and Vortechnics.

used in stormwater ponds?

To be accepted in the State of New Jersery, the device needs to be verified by the New Jerser Corporastion for Advanced Technology (NJCAT). To date the only system verified is again the StormFilter.
For more information please visit their websites.

All of these technologies have pro's and Con's. Vortechnic's is like the "catalac" of oil/grit separator's but you'll pay for it just as you would the car. I believe there are other companies that can treat similar sediment loads and flow rates at a lesser cost. Stormceptor requires a deep excavation but it's the simpliest of the oil'grit separator's but they have many critic's (rbannerman@dnr.state.wi.us). Aquashield's AquaSwirl has gained recognition for proven preformance and is really moderately priced in comparison to others.
Here is one study that that was completed in Washington State.
