Finite-Dimensional Methods for Optimal Control of Autothermal Thermophilic Aerobic Digestion [PDF]

open access: yes, 2012
An activated sludge process (ASP) is a biochemical process employed for treating sewage and industrial waste-water, which uses microorganisms and air (or oxygen) to biologically oxidize organic pollutants, producing a waste sludge (or floc) containing the oxidized material.

Ultrasonic Disintegration of Municipal Sludge: Fundamental Mechanisms, Process Intensification and Industrial Sono‐Reactors

open access: yesChemPlusChem, Volume 89, Issue 10, October 2024.
Sludge disintegration is a key challenge in environmental management, requiring advanced techniques for effective treatment. This paper aims to discuss the ultrasonic disintegration as a pretreatment for sludge to enhance anaerobic digestion. Fundamentals of ultrasonic cavitation, involving thermal destruction, hydromechanical shear forces, and radical
