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.

Hi Please try to solve Last time you solved this problem but result is incorrect.
Wastewater,.
The saturation DO concentration of a stream is 9.1 mg/L. At a sewage outfall, the DO of the stream is 8.0 mg/L. The stream has a reaeration constant of 4/day and a deoxygenation rate constant of 0.1/day. The initial ultimate BOD in the mixing zone is 200 mg/L. The time after the discharge at which the water will reach its minimum DO is most nearly a) 1.0 hr b) 1.7 hr c) 21 hr d) 34 hr e) calculate the minimum DO (in mg/L).
