() A wastewater sample is being analyzed to determine its BOD content. The sample is diluted in order to perform the test 295 ml, of distilled water are added to 5 ml of sample to fill the 300 ml BOD bottle. The bottle has an initial dissolved oxygen concentration of7.9 mg/L After incubating 5 days, the dissolved oxygen concentration is 45 mg/L a. What is the S-day BOD of the wastewater? h.

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.
