I'm a Chemical Engineer and I have some papers related to the evaluation of wastewater reuse through Process Integration and the use of Process Simulation. I'm not sure that this is what you are searching for but you can read my paper abstracts on my profile and if you are interested on something, please ask me. Also some my colleagues have other papers related to the wastewater treatment.
You can treat the waste water through many methods (electrochemical, filteration, bioremediation etc). First choose which technique you want to enter. Then search for the articles accordingly.
