A wastewater treatment plant discharges of effluent into a stream. Just upstream from the discharge point, the stream has an ultimate BOD of 5 mg/L. Assuming a cross-sectional area for the stream equal to 100 m2, what ultimate BOD (in mg/L) would you expect to find at a point of 15,000 m downstream? Wastewater Flow: 4 m3/sec BOD (ultimate): 40 mg/L River Flow: 10 m3/sec Deoxygeneation constant kd: 0.22 day-1

Physical and Chemical features

The physical property of a compound could be determined without modifying the originality of the compound. Examples of physical properties are density, hardness, color, boiling, and melting point. The chemical property expresses the ability of a compound to undergo a particular chemical change.
