Though we wanted to consult with engineers inside of SSI about the final design for our sewage treatment plant%E2%80™s aeration system, we had to prepare a presentation for the state to get the funding and we were out of time. So we were able to use SSI%E2%80™s design tools to quickly evaluate diffused aeration options on their web site, and even look at drawings and calculations of our specific case. http://www.stamfordscientific.com/designyourplant.html
