Integrated Solid Waste Management

Integrated Solid Waste Management (ISWM) is a thorough waste suppression, compost, removal and recycling Program. An effective ISWM system considers how to suppress, manage and recycle solid waste in a manner that is most efficiently to protect human health and the surrounding. ISWM system requires evaluation of public wants and demands and then selecting and merging the most effective waste management activities for the proposed demands. The main ISWM activities for solid waste management are Waste prevention, Recycling and Composting, and Combustion and Removal and waste collection in a properly planned, constructed, managed and mitigated landfill areas. Each of these requires careful designing, financing, accumulation, and delivery of activities.

Q- If the BOD3 of a wastewater sample is 75 mg/L and reaction rate constant k (base e) is 0.345 per day, find the amount of BOD remaining in the given sample after 10 days.
If the BOD3 of a wastewater sample is 75 mg/l and reaction rate constant k (base e) is 0.345 per day, the amount of BOD remaining in the given sample after 10 days is 1. 3.21 mg/L 2. 3.45 mg/L 3. 3.69 mg/L 4. 3.92 mg/L
A BOD test is run using 100mL of treated wastewater. The initial DO of the mixture after diluting the waste sample with distilled water is 9.0mg/L. After 5-day incubation, the DO measured was 4.0mg/L. After a long period of time, the DO is 2.0mg/L and no longer seems to be decreasing. Assume that nitrification has been inhibited. Determine the following: a)BOD5 & BODu of the waste sample b) BOD5 of the mixture and c) k THANK YOU
After primary treatment, a municipal wastewater contains 150 mg/L BOD5. The wastewater flow of 0.44 m³/s (10 MGD) is then treated in an activated sludge system with an SRT of 12 d and an HRT of 6 h.

A wastewater sample was diluted 10% with tap water for conducting BOD Test. The DO content in wastewater sample was 1.2 mg/l and water was 6 mg/l. After 5 days incubation at 20°C, the DO of the sample was 0.5 mg/l. Calculate (i) 5 day BOD of wastewater and (ii) ultimate BOD. Assume K₂0 = 0.12/day. ion:
Hi Please try to solve Last time you solved this problem but result is incorrect.
A municipal wastewater treatment plant is installing completely mixed activated sludge to meet their NPDES permit of 15 mg/L BOD5. The mixed liquor concentration is 1,000 mg/L MLVSS. The wastewater flowrate going to secondary treatment is 0.170 m3/s and the BOD5 in that stream is 110 mg/L. Laboratory measurements of the growth constants show: Ks = 60 mg/L BOD5, um = 2.8 d-1, kd = 0.05 d-1, Y = 0.73 mg MLVSS/mg BOD5. Determine the required volume of the aeration tank.
A 5-day BOD test if performed on an industrial wastewater sample that contains no bacteria; therefore, a "seeded" BOD test is run. Ten ml of "seed" are added to 20 liters of dilution water. Thirty milliliters of industrial wastewater are added to a 300-ml BOD bottle, and the remaining volume consists of "seeded" dilution water. The average dissolved-oxygen concentrations of the diluted wastewater samples and blanks (seeded dilution water) on the first day of the test were 7.5 mg/L and 9.0 mg/L, respectively. After incubation of separate BOD bottles at 20 C for 5 days, the average DO concentrations of the diluted wastewater BOD bottles and seeded dilution water BOD bottles were 3.1 and 8.5 mg/L, respectively. Calculate the 5-day BOD of the industrial wastewater. I am unsure of how to solve for f given this information, where f = (% seed in D1) / (% seed in B1)
A wastewater sample subjected to standard BOD5 test yields a test result of 200 mg/L. The rate constant is 0.18/day at 20°C (to the base 'e'). Another sample of the same wastewater is tested at a temperature of 30°C. The time in days after which the BOD yielded is 200 mg/L is (up to 2 decimal places).
After primary treatment, a municipal wastewater contains 150 mg/L BOD5. The 3 wastewater flow of 0.44 m³/s (10 MGD) is then treated in an activated sludge system with an SRT of 12 d and an HRT of 6 h. Given the biokinetic parameters tabulated below, determine the limiting value of the biotreatment safety factor (dimensionless). Parameter Value 3d¹ 60 mg/L BOD, 0.10 d¹¹ 0.6 mg VSS/mg BOD5 Ks ka Y 2
