A lagoon with a volume of 1500 m3 reieves an industrial wastewater flow of 100 m3/day containing a conservative pollunt at a concentration of 0 mg/L. a. Assuming that complete mix conditions are acheived in the lagoon, determine the concentration of the conservative pollutant in the effluent from the lagoon at steady state. b. If the influent pollunt concentration is suddenly increased to 60 mg/L, what would the effluent concentration from the lagoon be 7 days later?

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.
