A flowing stream has a temperature of 14°C, flow rate of 3.0 m}sec, saturated dissolved oxygen content and BODs of 15 mg/L with reaction rate constant of 0.13/day. Waste is discharged into the stream at a flow rate 0.5 m3/sec, temperature of 30°C, ultimate BOD of 50 mg/L and dissolved oxygen content of 2.5 mg/L. The discharged waste has same characteristics as the initial pollutant in the stream with the same reaction rate constant of 0.13/day.Determine:1. Temperature of the resulting combine flow at the mixing point2. Ultimate BOD of the combine flow at the mixing point. 3. Dissolved oxygen content in the combine flow at the mixing point. 4. Oxygen deficit in the resulting combine flow at the mixing point.5. Oxygen deficit and dissolved oxygen content in the stream at exactly one day after the initial mixing of the waste into in the stream if the deoxygenationand reaeration rate constants are 0.2/day and 0.4/day, respectively.6.

A light manufacturing facility produces 125,000 gallons per week of sanitary sewage and uncontaminated wash water which are discharged to a municipal sewer system. A small parts rinsing operation flushes about 12 ounces per week of trichloroethylene down the sink. Does the facility have to manage their wastewater as hazardous waste (see 40 CFR 261.3)?
the combined volume of waste water from the process and wash, and cooling and sanitary waste from an industry is reduced by
