Dear Venkata

I would recommend you the CAPTED WORK software from Hydromantis.

The user-friendly drag and drop interface and comprehensive database of unit processes allows users to quickly and easily assemble a treatment plant model, enter characterization data, and run simulations. Develop and optimize advanced control schemes, predict effluent quality under varying conditions, conduct planning and capacity analysis or offer sophisticated training and development programs with a dynamic model of your actual or proposed plant.

Here is the link of website:

Hi Venkata, I suggest you to have a look to the Delwaq software for water quality monitoring, very reliable I hope. I used Ribasim software of the Delft team for water allocation.

Modelling and simulation of German BIOGEST/EL-AGAMY wastewater treatment plants – Egypt using GPS-X simulator

Let me recommend to yo our book /report entitled:

Mechanism and design of sequencing batch reactors for nutrient removal, Artan & Orhon, 2005, IWA Publishing, 

It has al the required design algorithms you would need.

I would add STOAT, which is free.

CAPDET is steady-state and will be awkward with designing something that is intrinsically unsteady-state.
