Generic WWT Design Basis for Different Scenarios?

[waynef43]

I've been given a difficult task. I am a chemical process engineer and not a wastewater engineer. I don't know where to start.

We are a startup with a specialized wet process designed to scrub flue gasses in, primarily, the power industry. I have been tasked with coming up with a generic process and options that would meet the needs of any client and any scenario.

Our process produces large volumes of wastewater and concentrations of sulfuric acid and nitric acid up to 10%. We'll also have all of the heavy metals Inand other contaminants that you might expect to find as a result of coal combustion.

Is there any type of generic flow chart available that might provide me a starting point? Are there any resources that might provide me with various options depending on the operating and regulatory environments? Any other advise?

Thanks for the help!

Review the wikipedia article. There is a listing of various technologies in the reference list.

Thanks but this wikki page only discusses technologies capable of scrubbing SO2. I'm interested in treatment of the liquid effluents.

Siemens has presented a generic FGD treatment scheme in the link below. Further discussions with the utility about their specific power plant will enable an optimized system.

Bench and pilot testing will be critical for the success of an application.
