Concept explainers

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.

After initial mixing of a wastewater discharge in a 5-m-deep river, the DO concentration in the river is 7 mg/L and the temperature is 22°C. The average flow velocity in the river is 6 cm/s.(a) If the ultimate BOD of the mixed river water is 15 mg/L, the rate constant for BOD at 20°C is 0.5 d−1, there is negligible removal of BOD by sedimentation, and the reaeration rate constant at 20°C is 0.7 d−1, estimate the minimum DO concentration in the river.(b) How far downstream of the outfall location will the minimum DO concentration occur?

Please design a rapid sand filter that will effectively remove 65% of thesuspended solids in a flow of 10 cubic meters per minute. The suspendedmaterial consists of particles that are perfectly spherical with a diameter of 10microns. Please use sand with an effective size of 1 mm and a porosity of 0.5.You should limit your clean bed head loss to 0.5 meters per meter.
