Question

Hello,

I hope you are well. I was told to resubmit the question, but this is the full question. I do not understand how to solve part a and removed part b. 

I hope you can help. Thank you very much. 

If you are designing a monitoring program for
dissolved oxygen in a stream that receives
inputs from a wastewater treatment plant, and
the average stream velocity is 30 meters/min,
the de-oxygenation rate coefficient (ka) is 0.3
day-1 and the re-aeration rate coefficient (ka) is
0.5 day1. (a) Where specifically (meters
downstream of the discharge), should a
sample be taken to determine the greatest
dissolved oxygen impact? (b) There is a water
quality criteria that states that DO may not fall
below 4.2 mg/L, if the initial oxygen deficit is 0
mg/L and oxygen saturation is 8 mg/L, what is
the maximum allowable ultimate BOD
concentration (Lo)? What impact do you think
an elevated SOD value have on this situation?
