A stream flows through a small town where an industry discharges its effluent into the stream. Upstream characteristics prior to industrial discharge are as follows: fow rate 1000 m3/d, BOD5 2.5 mg/L, nitrates 2.0 mg/L, and temperature 19°C. The industry discharges at 50 m3/d. According to regulatory requirements, the maximum allowable values in the stream following any discharge are BOD5 30 mg/L, nitrates 4.0 mg/L, and temperature differential of 4°C from upstream conditions. Calculate the maximum allowable values for the industrial discharge

Question
A stream flows through a small town where an industry discharges
its effluent into the stream. Upstream characteristics prior to industrial discharge are as follows: fow rate 1000 m3/d, BOD5 2.5 mg/L,
nitrates 2.0 mg/L, and temperature 19°C. The industry discharges
at 50 m3/d. According to regulatory requirements, the maximum
allowable values in the stream following any discharge are BOD5 30
mg/L, nitrates 4.0 mg/L, and temperature differential of 4°C from
upstream conditions. Calculate the maximum allowable values for
the industrial discharge.
