OK Guys in my last thread http://www.homebrewtalk.com/f35/interesting-find-any-suggestions-15289/
I showed everyone what I found at work. It is spotless. I have removed the eyewash stuff and installed some valves and pressure taps
The green valve is to isolate gas in. Also the tee is for a pressure gauge at a later date. The green valve also releases any air left in the fermenter. I should be able to push in Nitrogen to push the trub and beer out of the black valve. The bottom of the fermenter is round not conical. I figure if I pressurize the fermented beer at the gas inlet (green valve) that I should be able to throttle down on the liquid discharge (black valve) to get just the trub blown off a few times, then I should be able to get clean beer to flow. The siphone tube inside the tank is like a 1/4" off the bottom directly in the center of the rounded bottom.
Any comments and suggestions are welcome and needed. The top tap over the green valve will also be able to be used for an airlock.
Thanks to everyone
