I don't know how to obtain the mass balance at the mixing point  (how did they come up with that equation). I was wondering if there is info on this in the CERM.

Any help would be appreciated

I'm not sure where in the cerm that is. It is in the WRE depth manual. It would also be in a intro to environmental engineering book.

 
@Lopez FYI, that formula is on page 28-10 in the 13th edition of the CERM under "Dilution Purification."

 
Thank you, its in the same page in the 14th edition. I was seeing the pattern but I wanted to know if there was more info about this and you pointing out where is located in the CERM really helps out.

Thanks again
