I think I’m going to use your own language to answer you.

Your statement in #30, “The modern refineries typically release cooling water cleaner than the water they take in, if they have any release at all.”

is totally FALSE and ......

Now you posted:

“”The reject of the separators, skimmers and filters GO BACK INTO THE RIVER OR CANAL.””

- - - -

“Your assumption is false.”

Here is my answer that you “missed” in my #35:

“”The back flush of filters using same river water is pumped back in the river. IOW, you saw the clearer water but not the back flush carrying what was in it in the first place because of a different exit point into the river downstream the first one.””

The OPERATIVE WORD IS “DOWNSTREAM!” Get it? Maybe further explanation about plant design is needed below.

You wrote:

“It is feed into the process and waste streams of the plant. Just as our storm water inside the plant boundaries.”

There’s a waste treatment plant inside the plant boundary. It’s sized for the maximum flow rate of plant waste effluent PLUS a safety factor. It’s NOT designed to handle the river water intake reject for many reasons.

The reject from the river water filters back wash, which is NOT contaminated, is pumped DOWNSTREAM (yeah, it’s that crazy word again) the waste treatment plant, IOW, IT BYPASSES the waste treatment plant inside the main plant boundary. It could be connected to the main plant effluent (cleaned up process waste) pipe and into the river at a specified minimum distance DOWNSTREAM the river water intake, or is run independently back to the river depending on pipe runs and cost.

Conclusion:

- my assumption was NOT an assumption. It’s simple engineering.

- it wasn’t false.

You should have read my post(s) thoroughly before jumping to the wrong conclusion or judgement.

Have a good day.
