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 municipal wastewater flow of 1,000 m³/d contains 400 mg/L BOD5 and is treated to be in a trickling filter. The filter will use a plastic filter medium with a specific surface area of 200 m³/m² and will operate with a recirculation ratio of 100% and a hydraulic loading of 25 m³/m² -d. Taking both surface loading and volumetric loading criteria into consideration, what volume (m³) of plastic media should be installed?
