Calculations for this question should be uploaded. Please make sure that the file is legible.

A wastewater treatment plant is designed to remove $1,500kg$ of BOD per day and nitrify $200kg$ of Ammonia with no denitrification

i$)$Calculate the Volume required when the BOD loading rate is $1\mathrm{.}2kg\frac{m^3}{?}$ day.

ii$)$ If the MLSS concentration is $3000m\frac{g}{\text{I}}$ what is the $F$ to $M$ ratio? is this sufficient for nitrification to take place.

iii$)$if the waste activated sludge concentration is $2\mathrm{.}5$ times higher than the MLSS what volume of sludge must be wasted to maintain an SRT of $15$ days.

iv$)$If the BOD to biomass ratio in the sludge is $1\mathrm{.}42.$ What volume of air is required to supply enough oxygen for both the BOD and the ammonia oxidation?

v$)$ If the system was converted to a Membrane Bioreactor and the MLSS increased to $11,500m\frac{g}{\text{I}}$ how much additional BOD could be treated per day?
