The anaerobic digestion technology has been in existence for centuries and its underlying
theory established for decades. It is considered a useful technology for the generation of …

A comprehensive review was carried out on the influence of mixing on anaerobic digestion
(AD) efficiency in stirred tank anaerobic digesters. Though traditionally, stirred tank digesters …

This article is a critical review of the state-of-the-art of computational fluid dynamics (CFD)
used to investigate bioreactors that produce biomethane and biohydrogen by means of …

Abstract In recent years, Computational Fluid Dynamics (CFD) methods have increasingly
been used to characterize hydrodynamics and mass-transport in wastewater treatment units …

As a lignocellulose-based substrate for anaerobic digestion, rice straw is characterized by
low density, high water absorbability, and poor fluidity. Its mixing performances in digestion …

Gas-mixing is commonly applied in anaerobic digesters, yet the resulting flow and hydraulic
mixing are difficult to evaluate because of limited full-scale experimental data and …

This work has investigated the effect of stirring on the performance of two anaerobic
digesters for a period of six years. In each digester, two propellers and one hydro-mixer …

To analyze the flow characteristics of the gas-mixed high solids anaerobic digestion (HS-
AD) system and optimize the mixing performance, the mixing performance of gas and non …

Anaerobic digestion is a widely used process for organic waste treatment and biogas
production. It is a complex process involving four main biochemical reactions, four microbial …

Fermentation material fluid mixing is an indispensable subsidiary technology for modern
biogas engineering, which can increase fermentation efficiency substantially. Taking …
