i m approached t help design a WW treatment plant for municipal waste water. i am not confident about the modes i am using for detailed design and calculations and through that to develop our own wold be like reinventing the wheel. so i searched online for some software that could help me to check the results and give confidence not to over or under design the system. i am already search out but i am not sure if the people in the industry are using the same.
Dear Anand,
It would be hard to find out open source design software, but there are certain software available for testing & simulation of treatment process. One of them is GPS-X is the most advanced tool available for the mathematical modeling, simulation, optimization and management of wastewater treatment plants.
please following link for the same

For open-source software I think all that is now available is the Modelica wastewater treatment library. There used to be a comparable version for Scilab, but it is no longer readily locatable.
For free, but not open source, there is STEADY, a steady-state program; SSSP, an early implementation of the ASM1, which may no longer run under Windows 7 64-bit and later - it is a 16-bit implementation, and is, I think, DOS-based. And then there is STOAT, from WRc, which I work on.
If you have money to spend then look at GPS-X or Biowin. Good things are being said about SIMBA#, and SUMO, from Imre Takac - Dynamita.com - also has good things said about it. And finally, there is WEST from DHI, which may be more expensive.
Naturally, I suggest start with STOAT - free. All the commercial offerings will give you good results; SUMO looks as if it will be the lowest cost, but it is still under development and final prices have not been released. SUMO may also be the easiest to modify, should you need to do this.
Thanks Jeremy. Sumo is completely open process source code and costs 2000 USD per year for a lease. We're in final beta, closing on on the release.
How big a wastewater plant is this? If it is small enough you can get a package plant suppliers to provide their designs by providing them influent and required effluent data. But when you design larger plants, an engineer with the proper experience should be doing the design.
The best is Hydromantis - GPS-X software. Support is on the site, and stuff are very polite to serve questions like this. Mr. Snowling has also answers on YouTube. It can fit to komunal and some industrial applications. But realle You will not find better soft, even if You start to investigate.
Victor, I know your valued opinion is based on a thorough investigation after you tried all free software and bought all the commercial ones. So we're waiting for an order :-). Thanks, I agree GPS-X is a nice package, I designed and wrote the process part of it in the last century... And Spencer is an excellent guy, he was my student at one time. However there is simply no "best" software for every purpose. If you want to spend an hour designing a plant, get an Excel sheet from someone, if you have 4 years of PhD and coding inclinations, use Matlab, and of course all simulation software fall somewhere in between, making life easier to achieve specific objectives.
OK, Imre, - privet!
Just some moments: 1- I am not dealer for Hydromantis, I am the user only, 2- nobody can use Excel sheet from someone, because not sure on result of evaluations (suppose to be checked all equalations), 3- MathCAD & MathLAB - exellent tools, always relay on result! Good luck, friend. I am new here and don't know regulations well.
I think you can use STOAT software

Thank you Ahmed Aboulfotoh sir,
i hope all going well with you.
i have gone through given link by you but there is showing some error hence i am unable to download this software.
Ahmed sir,
now i got one email on same error page. i will contact through same email may be i will get positive response.
thanking you
GPS-X is excellent software that can be used for simulation of wastewater treatment processes.
The answers above all point to software for simulating activated sludge systems. In addition to the ones listed there is ASIM from Eawag that is now freely available (http://www.asim.eawag.ch/).
But in the end, all simulation software should only be used if the user understand the background. The following excellent report provides extensive background: Rieger, L., Gillot, S., Langergraber, G., Ohtsuki, T., Shaw, A., Takacs, I. and Winkler, S. (2013) Guidelines for Using Activated Sludge Models, IWA Publishing.
...but in the end, I am not sure whether Anand is actually looking to do mathematical modeling? Best, Eberhard.

Eberhard, ASIM does activated sludge. But the rest tend to do more - at least anaerobic digestion, and most biofilms as well.
As well as ASIM, Aquasim is also available from EAWAG - and is free, does biofilms and anaerobic digestion. But is not that easy to use!

I will write it down with mathematical notations, we have a time series of measurements of sewage quality at the inflow:
x1(t1), x1(t2), x1(t3), ..., x1(ti)
x2(t1), x2(t2), x2(t3), ..., x2(ti)
for these values and the accepted calibration parameters (k1, k2, k3) correspond to the output values obtained from the simulation: y1(t1), y1(t2), y1(t3), ..., y1(ti) If I enter the uncertainty of the calibrated parameters using the Monte Carlo method, I will have to sample them n times. This way I should get k of modeled time series from the calculations. This means that for n=1 y1(n=1,t1), y1(n=1,t2), y1(n=1,t3), ..., y1(n=1,i)
for n=2 y1(n=2,t1), y1(n=2,t2), y1(n=2,t3), ..., y1(n=2,i) …
for n=k y1(n=k,t1), y1(n=k,t2), y1(n=k,t3), ..., y1(n=k,i) T
hus, we cannot find these modeled k- time series.
How to find output from MC simulation ?????
