Description
Several constituents of concern (COC) are problematic for coal ash leachate pond waste management, and even more so with the effluent limitation guidelines continuing to become more stringent. Filtration management of leachate ponds continues to have difficulty with effective removal of metals such as selenium, arsenic and boron to the wastewater discharge allowances. A novel technology has proven success in providing a chemical-free, high-volume alternative to traditional filtration in the coal ash and energy space. The technology meets or exceeds permitted allowances for discharge and is rapidly deployable as a mobile technology in addition to the ability to scale for more permanent needs. The use of permanent membranes that are high-solids tolerant even to reverse osmosis pore throat sizes eliminates the need for pre-treatment of the leachate ponds, providing operational expense reduction from chemical treatment and disposal of filter media or cartridges. In addition, the technology has a very small footprint, resolving another complex hurdle that has proven difficult to overcome. This presentation will provide both technology-specific information as well as independent analytical results from a large volume project.
