Residual activated sludge composition
WebApr 10, 2024 · Anaerobic digestion (AD) of waste activated sludge (WAS) is usually limited by the low generation efficiency of methane. Fe (III)-loaded chitosan composite (CTS-Fe) have been reported to effectively enhanced the digestion of WAS, but its role in promoting anaerobic sludge digestion remains unclear. WebIf primary sludge is sent directly to an anaerobic digestion process, the operator will want the sludge pumped to have a 4% to 6% total solids concentration. A typical surface overflow rate range for a primary clarifier receiving raw wastewater as well as the plant’s waste activated sludge is 600 - 800 gpd/sq ft.
