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.

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)
