“…Compared with BIOPAQ @ IC, BIOPAQ @ ICX has a different construct: instead of having a three-phase separator, BIOPAQ @ ICX separates gas on the top level while biomass separation occurs in the bottom of the reactor, which enhances efficiency and prevents sludge wash out. Spare vol- ume in the reactor will be used at its full potential, therefore decreasing the volume of BIOPAQ @ ICX [11]. In 2013 and 2014, BIOPAQ @ ICX was tested in the Netherlands and after its success, the system was applied to a brewery, a sugar processing plant and two paper plants in France and Hungary.…”

Internal Circulation reactor (IC reactor) is an anaerobic digestive system with the capability to treat high-load Chemical Oxygen Demand (COD) of industrial wastewater (e.g. brewery, potato starch, pulp and paper). IC reactor advantages include of the following: only small areas required, shock load resistance, produces more biogas and uses less energy compared to the Upflow Anaerobic Sludge Blanket (UASB) reactor. BIOPAQ@ICX is an upgrade to BIOPAQ@IC that has higher efficiency, lower volume, able to build from the current anaerobic reactor, and its trial has produced positive results in many different countries and with various types of wastewater. A case study of the wastewater treatment plant at Saigon Paper’s mills shows that the IC reactor COD removal rate is over 80% when the COD is not over 2300 mg/L; Volumetric Load Rate (VLR) is 6–14 kgCOD/m3.day and the removal rate is higher with a higher load and could reach 80% at 14 kgCOD/m3.day; granular sludges settle very well, and the three-phase separator is efficient of preventing sludge from washing out; pH, Total Suspended Solids (TSS), alkalinity, Volatile Fatty Acids (VFA), N-NH4+, P-PO4 3-, Ca, SO4 2- were also analysed and indicated that the IC reactor is operating well.

“…Animal manure and organic sludge of aerobic wastewater treatment processes are among the most widely used feedstock for anaerobic digestion (Chaiprasert, 2011;Horváth et al, 2016). AD can convert dry as well as wet feedstock; a wet digestion process uses a pumpable aqueous slurry containing 15% (w/w) dry solids as feedstock while dry feedstock are sufficiently dry to be stackable (Valijanian et al, 2018). Feedstocks of plant origin which contain lignin, cellulose and hemicellulose are referred to as lignocellulosic feedstocks while those which do not have these components are non-lignocellulosic e.g.…”

“…There are also the anaerobic sequencing batch reactor, continuous stirred tank reactor and anaerobic plugflow reactor, based on conventional types of chemical engineering reactor (Abbasi et al, 2012;Talia, 2018;Valijanian et al, 2018). The anaerobic sequencing batch reactor is loaded one time at the fill stage and all digestate formed during digestion is recirculated until the end of the cycle; it is the most suitable for very dilute manure of <1% TS (Abbasi et al, 2012;Talia, 2018).…”

“…In addition to these, other reactors have been designed to enhance the retention of active microbial sludge, increase the rate of substrate conversion and reduce hydraulic retention time in the anaerobic digester, these are referred to as sludge retention reactors (Valijanian et al, 2018). They include the anaerobic contact reactor (Capela et al, 2009;Şentürk et al, 2010;Şentürk et al, 2013), up-flow anaerobic sludge blanket reactor (Mao et al, 2015;Reungsang et al, 2016;Jiang et al, 2014), expanded granular sludge blanket reactor (Mao et al, 2015), up-flow anaerobic solid-state reactor (Mumme et al, 2010;Pohl et al, 2013 ), anaerobic baffled reactor (Mao et al, 2015), internal circulation reactor (Tauseef et al, 2013;Mao et al, 2015;Wang et al, 2017), anaerobic fluidized bed reactor (Zhang et al, 2008), anaerobic membrane reactors (Skouteris et al, 2012;Visvanathan and Abeynayaka, 2012;Ozgun et al, 2013;Horváth et al, 2016) and anaerobic biofilm reactors (Karadag et al, 2015).…”

Anaerobic Conversion of Biodegradable Municipal Solid Waste to Biogas: A Review

et al. 2019

View full text Add to dashboard Cite

Huge quantity of Municipal Solid Waste (MSW) is generated daily. This waste comprises a biodegradable portion which can be converted into biogas (bioenergy) by anaerobic digestion (AD). This study reviews MSW and its management, AD feedstock and their characteristics, factors affecting biogas production in a biodigester and anaerobic co-digestion of Organic Fraction of MSW (OFMSW) with other substrates. Municipal solid waste is managed through waste diversion (reduction, reuse, recycling and recovery) and waste disposal (controlled incineration, landfilling and controlled dumping). AD feedstock includes agricultural waste/residues, animal wastes, energy crops, food waste, forestry crops and residues, organic industrial waste and wastewater, weeds, aquatic algae, sewage and OFMSW. The essential factors that influence the production of biogas are temperature, pH, mixing rate, carbon/nitrogen ratio, organic loading rate, micro and macro-nutrient availability, retention time, nature of the feedstock and digester type. Anaerobic co-digestion of OFMSW with other substrates results in improved AD process stability, enhanced biogas productivity, maximization of the capacity of available feedstock for anaerobic digestion. It is also a cost-effective and improved technique to optimize anaerobic digestion process via the increase in nutrients and bacterial variety in substrates. The generation rate and composition of MSW, as well as the characteristics of OFMSW feedstock for anaerobic digestion, are required for the design of a full-scale biodigester for municipal use. The information provided in this review is invaluable to researchers, governments, industries and other stakeholders interested in anaerobic conversion of biodegradable solids to bioenergy.
