A comprehensive review on rheological studies of sludge from various sections of municipal wastewater treatment plants for enhancement of process performance

Abstract: Large quantities of sludge is generated from different sections of a wastewater treatment plant operation. Sludge can be a solid, semisolid or liquid muddy residual material. Understanding the flow behaviour and rheological properties of sewage sludge at different sections of a wastewater treatment plant (WWTP) is important for the design of pumping system, mixing, hydrodynamics and mass transfer rates of various sludge treatment units, optimization of conditioning dose and for sustainable sludge management.

“…The present work has been conducted on a specific horizontal tube-flow configuration. It possesses an interest for the handling of complex so-called frictional fluids in geometrical confinements, such as innovative catalytic processes [36], or waste water or biomass slurries management [37,38]. We provide here observations and discussions about competing or collaborative effects of viscosity, solid friction and capillarity leading to diverse flow behaviours ranging from non-Newtonian rheological properties to pattern formation.…”

“…The most common FFVW stabilization technology in world-wide practice biological, thermal and thermochemical process that includes land lling, composting, incineration and anaerobic co-digestion (Balussou et al 2012;Mozhiarasi et al 2020). Land lls technologies has adverse impacts on soil, groundwater, and climate, while incineration of FFVW increases air-pollution by the emission of harmful gases such as oxide of sulphur and nitrogen, and other greenhouse gases in the environment (Hong et al 2018;Sittijunda and Reungsang 2018). Among these waste stabilization techniques only few are sustainable such as anaerobic co-digestion etc.…”

“…Various technologies have been adopted for the degradation of dyes from wastewater, including advanced oxidation processes (AOPs), adsorption, biological and chemical methods, and the use of membrane modules [8][9][10]. Fenton oxidation-based AOPs are among the most effective processes because of their relative ease of operation, low-cost facility, and high removal efficiency [11,12].…”
