How the … WebMicroscopy inspection of the morphology of activated sludge (AS) flocs can provide important information regarding the AS properties, which strongly affect the performance of AS systems. However, the acquisition of such information from microscopy inspection results requires skilled and specialized expertise.
WebApr 8, 2024 · Moreover, the unreasonable disposal of iron-rich sludge leads to secondary pollution (Bashar et al., 2024). Fortunately, if the iron in the sludge is recycled, both the treatment cost and total sludge volume can be greatly reduced (Xu et al., 2009a). Several techniques have been developed to recover iron from iron-rich sludge.
