Modelling the rheological properties of sludge during anaerobic digestion in a batch reactor by using electrical measurements.

摘要: Anaerobic digestion is a significant process leading to biogas production and waste management. Despite this double interest, professionals still face lack of efficient tools monitor manage the whole procedure. This especially true for rheological properties material inside reactor, which are major importance anaerobic However, can hardly be determined in-situ it would very helpful determine indicators their evolution. To solve problem, paper investigates evolution sewage sludge electrical during in batch reactor. We focus on apparent viscosity complex impedance, measured by impedance spectroscopy. Both them modelled linear combination raw inoculum properties, weighted time-dependent coefficients. Thus, determining digested signature, possible obtain those coefficients model viscosity. work offers many theoretical practical prospects.
