Control of Manganese Dioxide Particles Resulting From In Situ Chemical Oxidation Using Permanganate

摘要

The primary technical objective of this research is to identify and evaluate a MnO2 particle stabilization aid that will facilitate transport of manganese dioxide particles to avoid their deposition in well screens, filter packs, and in subsurface areas of high contaminant saturation. This will allow practitioners currently implementing permanganate injection and/or flushing technologies to maintain improved hydraulic control at a treatment site by amending oxidant solutions with the appropriate stabilization aid. Furthermore, the research will provide for greater understanding of the potential impacts of various porous media and groundwater characteristics on particle genesis, growth, and transport, in general, thereby improving the understanding of potential impacts in and around the zone of permanganate emplacement.
