Concept explainers

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.

Q1.Clearly indicate if each of the following is True or False 1) The amount of bypassed water in split treatment of hardness depends on material balance on Mg². 2) Most water treatment plants in Iraq are using polymers as a coagulant. 3) In drinking water, most of alkalinity comes from SO4². 4) Circle or ring system is the most common method used now to design water distribution systems. 5) Fecal Coliforms and E-Coli are generally pathogenic and we need to test them to avoid their diseases. 6) In flocculation process, we need rapid mixing to enhance formation of flocs for better settlement. 7) In filtration, the only mechanism involved is the straining. 8) It is better to travel downhill, avoid rush hours, and avoid left turn when designing a route for packers. 9) Ozone in Stratosphere layer helps prevent UV light from reaching earth and causing skin problems. 10) Transfer station is used to transfer solid waste to final destination in more efficient way.
A water quality analysis of a well water used for drinking water in a rural home found an arsenic concentration of 0.5 micromolar. This value seems very small to you. But you need to see if it still exceeds the drinking water standard of 10 ppbm. Is the well water violating the standard (and therefore the water would require treatment)?
