WebbHigh levels of potassium permanganate are often used to treat eutrophic water bodies, which produce manganese-rich drinking water treatment sludge (DWTS). Although there have been some studies on recycling sludge in cement-based materials, little attention has been paid to the multiscale behavior of concrete with manganese-rich sludge. WebbHence, fecal sludge is highly variable, with a very wide range of quantities (i.e. produced and accumulated volumes) and qualities (i.e. characteristics).: 3 Fecal sludge is stored onsite, and is periodically collected and transported to a fecal sludge treatment plant, followed by safe disposal or end use.
