Feb 8, 2022 · Anaerobic fermentation can improve sludge characteristics, increase dewatering characteristics and remove organic matter, and the biogas produced is a high-quality clean energy source (Ting and Lee 2007). It has the advantages of protecting the environment and saving resources.
Sep 5, 2022 · The biological hydrogen production technology of organic wastewater fermentation method utilizes the biological anaerobic-acid-generating fermentation process to produce hydrogen, and can also be used as the acid-generating phase in the two-phase anaerobic biological treatment system.
Jul 21, 2020 · Silage is a crop preservation method based on natural lactic acid fermentation under anaerobic conditions . Silage can be used as an economical, low-consumption, and environmentally friendly preservation method, meeting the annual demand for high-quality raw materials for industrial production and increasing the value of artichoke by-products.
As aforementioned, dark fermentation (DF) is a biologi-cal hydrogen production method that falls under anaerobic fermentation in obscurity or in the absence of daylight. It is currently a more widespread technology owing to its envi-ronment-friendly nature, energy-ecient technique, and the fact that it necessitates less surface area. Microorganisms
May 9, 2022 · This article aims to present the results of research on anaerobic digestion (AD) of waste wafers (WF-control) and co-substrate system—waste wafers and cheese (WFC-control), combined with digested sewage sludge. The aim of this study was to assess the physicochemical parameters of the diatomaceous earth/peat (DEP; 3:1) carrier material and to verify its impact on the enzymatic activity and
Jun 20, 2024 · fermentation, chemical process by which molecules such as glucose are broken down anaerobically. More broadly, fermentation is the foaming that occurs during the manufacture of wine and beer, a process at least 10,000 years old. The frothing results from the evolution of carbon dioxide gas, though this was not recognized until the 17th century.
Mar 15, 2010 · Moreover, the mechanism of VFA improvement was also explored. It was suggested that anaerobic fermentation process at pH 10.0 should be reconsidered to be applied as an eco-friendly material recycling process, based on its sludge dewaterability and total bromate.
