A mine is planning to use a silty sand mixed with sodium enriched bentonite to line a wastewater lagoon that will retain process water from mineral extraction. The lagoon will retain the water before it is treated at the wastewater treatment plant. Calcium enriched lime is added to the water during the mineral extraction process, which leaves the water rich in calcium. Will the process water affect the hydraulic conductivity of the silty sand-bentonite mixture? Why?

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.

Question

A mine is planning to use a silty sand mixed with sodium enriched bentonite to line a
wastewater lagoon that will retain process water from mineral extraction. The lagoon
will retain the water before it is treated at the wastewater treatment plant. Calcium
enriched lime is added to the water during the mineral extraction process, which
leaves the water rich in calcium. Will the process water affect the hydraulic
conductivity of the silty sand-bentonite mixture? Why?
