Summary on Grant Application Form |
The work proposed will use recycled construction/demolition waste instead of dolomite in a novel manganese removal passive treatment system. Dissolved manganese causes major problems in the water industry as it causes pipe blockages, an unpleasant taste and also stains laundry. The Environment Agency are currently reviewing the Environmental Quality Standard and it could be reduced to as low as 0.03mg/l which would mean many discharges which comply with current legislation would fail in the future. Waste aggregates such as concrete, brick and stags provide a high pH environment which helps kickstart manganese oxidation. Manganese oxide will then accrete onto the substrate and take over as the main catalyst thereby preventing further substrate dissolution so that the general water environment does not suffer from high pH conditions. In addition, the system ensures a constant supply of fresh manganese oxides which are powerful sorbents of other more ecotoxic metals. Long-term field trials will prove time viability of this low-cost technology for potential beneficiaries including both the industries which are currently unable to dispose of their waste products and those communities which are affected by manganiferous mine or leachate discharges. The work will also promote sustainability through the reduction of orimarv aaareaete extraction and reduction of waste to landfill.
