I didn’t say it made logic sense, it was based upon government permits.
Rotating screens or the like in the water were acceptable. Once it was taken into the the plants piping, any discharge, from any source, had a higher quality of the discharge than the original source of water.
These were places like on the Houston Ship Channel, the massive Freeport petrochem complex, Beaumont. They were all areas that in the past had very bad pollution in the water source. It surely was as you said, permits evolved over time.
I rarely work with that type of process of the plant. But they do need power for pumps, instrumentation, P&ID reviews; that is how I get involved. Strangely, I spent the morning with the City of Houston on helping to get an enlarged water intake from a canal out in Mont Belvieu. That facility has intake only, no outlets back to the water source.
“I didn’t say it made logic sense,”
For the record, I didn’t say that you said that. Hence, permits “evolved.”
Just to make sure there’s no misunderstanding.
I used to do all those things from start to finish. I enjoyed drawing the PFDs and the P&IDs on CADD, a no no to my boss! I was too damn expensive to do that, but I managed to conspire with CADD managers...it saved me a lot of time on back-checking, supervision, esthetics, etc.
I delegated the garbage we were talking about because I hated it and it reminded me of exactly that; garbage!
I had to deal with waste personally, I mean, no delegation, when I dealt with live virus’ kill systems and had to make absolutely sure it’s dead through redundant systems. No cutting corners by clients or “it’s all right, it’ll work” attitude, NONE!
