3) Based on the results from problem 1 and 2, estimate the hydrocarbon saturation in the reservoir if the log analysis indicates that the porosity is 20% and the true formation resistivity is 5.25 Nm.

A complete mix activated sludge system is being designed to address a flow from a primary treatment process of 1000 m³/day. The design includes a 6-day solids retention time and typical kinetic parameter at 15°C. The wastewater has a bCOD= 192g/m³, nbVSS=30 g/m³, and an inorganic concentration of 10 g/m³. The aeration tank should maintain a concentration of MLV-=2500 mg/L. Assume the rbsCOD is equal to BOD and that it is typically 68% of the bCOD. Provide detailed calculations and an explanation of the steps you performed.
