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 system is designed to treat contaminant X with two PFRs in series. The concentration of contaminant X entering the first PFR is 120 mg/L and the inflow is 420 L/s. The first PFR is 5000 m³ in size, and the contaminant reacts via first order kinetics with a k value of 0.50 (1/hr). The second tank is being built so that the treatment facility can meet the permit level for contaminant X of 9.4 mg/L. What size do they need to make the second tank in m³?
