You have been treating a wastewater with bacteria that have the following kinetic coefficients: k= 16 mg BODL/mg VSS-day Ks = 10 mg BODL /l b =0.2/day Y = 0.35 mg VSS/mg BODL fd = 0.8 A genetic engineer comes to you and claims he can “fix” your bacteria so they are more efficient. The fixed bacteria will have b=0.05/day and fd = 0.95, while all other coefficients are the same. Using a chemostat reactor, you were successfully using a safety factor of 30, and you plant to continue doing so. How would the genetic engineers plan affect your sludge production and oxygen requirements? Assume X0=0, S0=200 mg  BODL/l). In what ways are the new bacteria more efficient?

Question
You have been treating a wastewater with bacteria that have the following kinetic
coefficients:
k= 16 mg BODL/mg VSS-day
Ks = 10 mg BODL /l
b =0.2/day
Y = 0.35 mg VSS/mg BODL
fd = 0.8

A genetic engineer comes to you and claims he can “fix” your bacteria so they are more
efficient. The fixed bacteria will have b=0.05/day and fd = 0.95, while all other
coefficients are the same. Using a chemostat reactor, you were successfully using a safety
factor of 30, and you plant to continue doing so. How would the genetic engineers plan
affect your sludge production and oxygen requirements? Assume X0=0, S0=200 mg 
BODL/l). In what ways are the new bacteria more efficient?
