Nanoparticle (NP) use can increase biological activity and adversely impact the environment. This study was first to quantify biogas increases with NP mixtures during continuous anaerobic digestion (AD) of poultry litter uptake in crops through tracking: 1) CH4 H2S production from a mixture (Fe, Ni, Co) 30 L digester (AD1) for 278 days compared control (AD2) without addition, 2) degradation dig...

Although biogas has been primarily produced through liquid anaerobic digestion, this method leads to the floating and stratification of fibers non-homogeneous mixing, which can reduce yield. Alternatively, be by solid-state digestion (SS-AD) organic material with a high solid content, such as corn cobs. We investigated co-digestion food waste cobs biomass feedstock for SS-AD in production. meas...

Anaerobic digestion (AD) is a bioprocess that is commonly used to convert complex organic wastes into a useful biogas with methane as the energy carrier. Increasingly, AD is being used in industrial, agricultural, and municipal waste(water) treatment applications. The use of AD technology allows plant operators to reduce waste disposal costs and offset energy utility expenses. In addition to tr...

the effect of organic loading rate (olr) provided by hydraulic retention time (hrt) and influent chemical oxygen demand (codin) on the performance of an up-flow anaerobic sludge fixed film (uasff) bioreactor treating palm oil mill effluent (pome) was studied. anaerobic digestion of pome was modeled and analyzed with two variables i.e. hrt and codin. experiments were conducted based on a general...

The effect of different ozone doses was assessed in terms of biogas production, anaerobic digestion (AD) kinetics and concentration of amino acids (AA) and long chain fatty acids (LCFA) in the waste activated sludge (WAS). Four different ozone (O3) doses were used: 0.043 gO3/gTSS, 0.063 gO3/gTSS, 0.080 gO3/gTSS and 0.100 gO3/gTSS. The lower doses resulted in biogas production increases and fast...

The use of agricultural residues in anaerobic digestion (AD) for biogas production promotes environmental and socioeconomic benefits. This study aimed to evaluate the from dry coffee husks (DCH), wet (WCH), cattle manure (CM) AD. Prototypes Indian benchtop digesters with a batch feeding system supplied 100 CM, DCH, WCH mono-digestion (AMoD) 25:75 DCH:CM WCH:CM co-digestion (ACoD) were used expe...

Anaerobic digestion (AD) has been recently introduced as a promising technology for producing bioenergy around the world. Due to its especial characteristics, solid waste could be considered as a proper feedstock in the digester. Retention time (RT) and rate of biogas production are two major parameters affecting the efficiency of the process. The AD procedure of biogas production consists of h...

Anaerobic digestion (AD) is a complex biological system which can be affected by several operational problems. Among them, biological foaming is one of the most difficult to deal with. It has many effects, such as causing gas pipe clogging and probe failures, and it can affect mixing devices, etc. Since the mechanisms involved in biological foaming development are not fully understood, it is no...

Poor management of organic waste is a key environmental and public health issue as it contributes to contamination the spread diseases. Anaerobic digestion (AD) presents an efficient method for while generating energy nutrient-rich digestate. However, AD process limited by factors, which include inefficiencies from substrate-induced instability, poor quality digestate, effluent emissions. Latel...
