A settling chamber is to be used to collect particles of 50 micrometers diameter and 1400 kg/m3 density from a stream of air 1 atm and 300 degree kelvin with a volume flow rate of 2.5 m3/s. The overall chamber is 2m high, 4m wide and will have 25 trays including the bottom surface.

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.
