A BOD test is to be run on a sample of wastewater that has a five-day BOD of 195 mg/L. If the initial DO of a mix of distilled water and wastewater is 9.0 mg/L, and the test requires a decrease in DO of at least 2.0 mg/L with at least 2.0 mg/L remaining at the end of the five days, what range of dilution factors (P) would produce acceptable results? In 300-mL bottles, what range of wastewater volumes could be used?

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.
