A laboratory provides the following analysis obtained from a 600 mL sample of wastewater: total solids = 350 mg/L, total suspended solids = 210 mg/L, dissolved solids = 10 mg/L, and volatile dissolved solids = 90 mg/L. It was also recorded that the filter mass after drying at 103oC and after ignition at 550oC are 0.23 g and 0.135 g, respectively. Calculate the fixed suspended solids and total dissolved solids.

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.
