Environmental Engineering: A lake with a constant volume of 10*106 m3 is fed by a pollution-free stream with a flow rate of 50m3/s. A factory dumps 5m3/s of a nonconservative waste with a concentration of 100mg/L into the lake. The pollutant has a reaction coefficient rate, k, of 0.25/day. Assuming the pollutant is well mixed in the lake, find the steady state concentration of the pollutant in the lake.

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.
