2023/3/8/ · Sludge tanks are an essential component of wastewater treatment facilities. They act as a holding area for sludge — the biosolids coming from wastewater. Situated within the greater treatment process, sludge tanks often lightly process sludge through a process called thickening. This happens in a few different ways, but the result is
2021/4/1/ · 1. Introduction. Waste activated sludge (WAS) is an important by-product of biological treatment processes [1], WAS disposal generally accounts for 50 %–60 % of the total construction and operation costs of a wastewater treatment plant [2, 3].WAS contains elements such as N, P, K and rich organic matter, which can be used as a resource [4].In
As an inexpensive countermeasure, aeration of thickened sludge holding tanks (SHTs) was tested as a solution for mitigating the subsequent biosolids odor emission. Experimental results indicated that the extremely low-oxidation reduction potential (ORP) in the SHTs and the fermentation of high-rate-activated sludge were primarily contributors
The high-throughput sequencing method has been widely used in the microbial analysis of the sludge fermentation process, as well as the CEPS fermentation process, which
2023/1/1/ · Abstract. Acidogenic fermentation of sewage sludge for volatile fatty acids (VFA) production is gaining increasing attention due to their wide range of possible applications, sustainability, and circular economic value. The purpose of this chapter is to provide a comprehensive review of sludge-derived VFA production mechanisms and
2024/2/29/ · Special Issue Information. Dear Colleagues, Wastewater treatment facilities in China must produce a significant amount of sewage sludge due to the country's rapid urbanization and the rise in urban wastewater. This sludge contains potential resources including organic materials, nutrients, metals, and bioenergy that can be
A continuous stirred-tank reactor was used as an anaerobic sludge system and the hydrogen production capabilities of three typical fermentations, in terms of specific hydrogen production rates, were investigated under the same hydraulic retention times (8 h) and influent chemical oxygen demand (5000 mg/L) at 35 degrees C.
2022/2/28/ · sewage sludge, and the results showed that the presence of 30 mg Al/g TS of PAC in sewage sludge significantly reduces the production of short-chain fatty acids in sewage sludge anaerobic fermentation compared with the control group. The mechanism study shows that the inhibition phenomenon is caused by the flocculation of

Sewage sludge treatment describes the processes used to manage and dispose of sewage sludge produced during sewage treatment. Sludge treatment is focused on reducing sludge weight and volume to reduce transportation and disposal costs, and on reducing potential health risks of disposal options. Water removal is the primary means of

2014/10/1/ · In recent years, the recovery of VFA from the biological treatment of wastewater, sewage sludge, food and fermentation waste and lignocellulosic waste biomass through dark fermentation and
2022/2/28/ · With the annual increase in the sludge production in China’s sewage treatment plants, the problem of sewage sludge treatment and disposal is becoming more and more serious. Anaerobic fermentation can convert complex organic matter in sewage sludge into short-chain fatty acid, hydrogen, methane and other resources and is an …
2024/1/31/ · Special Issue Information. Dear Colleagues, In recent years, volatile fatty acid (VFA) production through anaerobic fermentation of sewage sludge, instead of methane production, has been regarded as a high-value and promising roadmap for sludge stabilization and resource recovery. Compared to methane, VFAs have a higher value …
