Dear all,
Very nice discussion. I also want to draw your attention to the recent development in the open source CFD community and the water/wastewater related work. The most popular one is probably OpenFOAM (http://www.openfoam.com/). It comes with a solver for settling tanks. If you do a google search, there are many using OpenFOAM for pumping stations, grit chambers, fish passages, UV disinfections, and other hydraulics/environmental problems.
We (myself and Prof. Garcia at University of Illinois) have been using/developing models based on OpenFOAM for more than ten years. For example,
X. Liu and M.H. García (2011). Computational Fluid Dynamics (CFD) Modeling and Optimal Design of Large-Scale Primary Settling Tanks.
Journal of Hydraulic Engineering, 137(3):343-355
I see a lot of values and potential of using CFD in our profession. OpenFOAM has been the workhorse in my research group and you can find a lot of information from our website.

Hi everybody,
There is a commercial application, named FLOW-3D. (http://www.flow3d.com/home/resources/case-studies/water-environmental)
It seems Flow-3D solutions is coupled to thermal energy transfer, 6-degree of freedom fluid-solid interaction, and mechanical and thermal stress analysis which is favored for free-surface flow modeling .
In the case studies section, you could find some related information to water and environment.

Thanks everyone!
I have been given some great information on folks who perform CFD modeling and where to go for help.
This has been a great way to get contacts and references for assistance in a special area I knew very little about.

Karen,
I suggest contacting Process Simulations, Ltd. at http://www.psl.bc.ca. PSL is a small spinoff consulting group from the University of British Columbia in Vancouver, Canada. The main contact is Dr. Martha Salcudean. They did some brilliant work for me, developing a CFD model to simulate flow patterns in aerated lagoons used for industrial wastewater treatment. They have much CFD experience with industrial processes and can be affordable, since they draw from a pool of graduate students.
Regards, Phil Pagoria

I am looking for an academic or sole practitioner who has experience using CDF modeling software to evaluate a wet weather well for waste water pump station.

Subject: CFD applications to water and wastewater treatment
Hello EWRI Colleagues,
I just graduated from a PhD program in Civil and Environmental Engineering at University of South Florida. In my PhD study, I studied disinfection process for water treatment and stabilized pond for wastewater treatment using computational fluid dynamics (CFD). CFD technology has been prevalent in aerospace engineering and mechanical engineering for many decades. But it was not popular in environmental engineering until recently. During a literature review, I noticed that there are more researchers outside the United States (e.g., Canada, UK, Germany, and France etc.) concerning improving the performance of disinfection tank and willing to explore the disinfection process using modeling tools (mostly CFD). I think it is an interesting phenomenon. But it may not be true. Please correct me if you happen to have a better knowledge in this field. Any other comments are also welcome.
Thanks,
Jie
