In order to improve the stability and CH 4 production efficiency of the anaerobic digestion
(AD) system under high ammonia nitrogen (AN) concentration, this study investigated the …

Volatile fatty acids and ammonia nitrogen (AN) accumulate during anaerobic digestion (AD)
of high N substrates, such as chicken manure (CM), causing decreases in methane yield …

The synergetic inhibition of ammonia and organic acids during anaerobic digestion with
high organic loading rate limits the methane yield and endangers process stability. Here, the …

Anaerobic digestion (AD) is a green technology widely applied to food waste treatment.
Although the AD has high efficiency, instability often occurs. The main purpose of the study …

Ammonia nitrogen inhibition is a well-known issue in the anaerobic digestion of food waste.
This study aims to investigate the influence of biochar on the performance and the microbial …

This study explored the mechanisms by which biochar mitigates ammonia inhibition in
anaerobic digestion (AD) of swine manure. Findings show 2–8 g/L exogenous ammonia …

This study aimed to investigate the effectiveness and mechanism of biochar and modified
magnetic biochar addition in improving the anaerobic digestion (AD) efficiency of swine …

The promotion effects of biochar supported nano zero-valent iron (BC/nZVI) with different
carbon/iron ratios on two-phase anaerobic digestion (AD) of food waste (FW) were studied …

The effect of biochar addition on the microbial community and methane (CH 4) production
during anaerobic digestion was experimentally investigated, focusing on the role of minerals …

The adsorption by biochar can effectively alleviate the problem of ammonia inhibition in
biogas engineering. Based on batch adsorption experiments, the effect of acid modifier on …
