As a wastewater technician you are receiving sewage with a biological oxygen demand of 200. Which process would be best to treat this sewage? As a wastewater technician you are receiving sewage with a biological oxygen demand of 200. Which process would be best to treat this sewage?
A.sludge digesters
B.secondary anaerobic treatment
C. bioreactors
D. secondary aerobic treatment
Homework Answers
BOD is level of oxygen in water that is by aerobic microorganisms that decomposing organic matter in water.
When BOD is 200 as per my view best treatment that given to water is secondary aerobic treatment because it is the best method to reduce BOD because BOD is high when in water high amount of aerobic material. So it's obvious that you should go with secondary aerobic treatment.

You have collected water samples of the influent (raw sewage) and effluent (treated sewage) at Houston Wastewater Treatment Plant. You plan to conduct the BOD5 test to determine the BOD rate constant, k. A. Would you expect the rate constants to be the same or different in these two samples? If different, which would be higher and why? B. If the BOD5 for the raw sewage sample is 600 mg/L, and the ultimate BOD is 650 mg/L at 20oC, find...

A wastewater treatment plant, which serves a population of 300,000 people, receives an average daily volume of 24 million gallons per day (MGD) at an average influent 5-day biochemical oxygen demand concentration of 200 mgBODs/L and an average influent total suspended solids concentration of 220 mgTSS/L. The plant operates a primary sedimentation process that remove 65% of the incoming TSS and 35% of the incoming BOD %. This process is followed by a secondary treatment process before discharge to the...

QUESTION 3 a) After a point of wastewater discharge, the dissolved oxygen (DO) concentration is found as 83.33% of the saturation DO. The remaining BOD after 5 days at the point of discharge is 10.13 mg/L. The BOD rate constant determined in the laboratory under standard conditions is 0.115/day. The saturation DO concentration in the river water is 9 mg/L. The deoxygenation and the reaeration rate coefficients are 0.25/day and 0.45/day, respectively. The river travels at a velocity of 0.12...
