Please Help me with this one as soon as possible. I need it by tonight. Thanks.
The lovely town of River City is situated along a scenic stretch of the Sweet-N-Pure River. The city is seeking a waiver from the state regulatory agency to permit it to discharge its partially treated wastewater into the Sweet-N-Pure. The regulators will give permission for the discharge if the city can show that the largemouth bass population in the river is sufficiently protected. This species of bass requires a minimum of 3 mg/L of dissolved oxygen to survive. Given the following information about the wastewater discharge and the river, estimate the minimum downstream concentration to determine weedier River City should get its waiver or be compelled to upgrade its wastewater treatment system. Data are as follows: Maximum steady-state waste discharge Minimum steady-state river flow Or Average cross-sectional river area A = 20 content in the wastewater content in the upstream river saturation concentration at 20 degree C IX), concentration in the wastewater concentration in the upstream river decay constant recreation constant for the riverExplanation / Answer
DO= 4.386 mg/L the city should upgrade thier wastewater treatment system because this amoubt of waste water can polute river water. which is bad for aquatic life and living organisms living in river. the river water if get polluted it will spread desises in enviorment which is harmful for evry one.
