Mathematical modelling of the internal circulation anaerobic reactor …
2019年4月18日 · In this study, the hydrodynamic characteristic of a lab-scale internal circulation (IC) anaerobic reactor was investigated. We found that the gradual Increasing-Size Continuous Stirred-Tank...
Internal circulation reactor - Wikipedia
The internal circulation reactor (IC reactor) is a form of anaerobic digester. It is primarily designed to treat wastewater. The IC reactor is an evolution of the UASB and EGSB digestion systems. The digester typically produces biogas with a high concentration methane (c80%). In essence the IC to improve digestion rates and gas yields.
High-performance internal circulation anaerobic granular sludge reactor …
2024年5月8日 · This research investigates the efficacy of a high-performance pilot-scale Internal Circulation Anaerobic Reactor inoculated with Granular Sludge (ICAGSR) for treating cattle slaughterhouse wastewater while concurrently generating biogas.
Study on the flow characteristics and the wastewater treatment ...
2014年12月1日 · Internal circulation (IC) anaerobic reactors can effectively solve the problem of the contradiction between long sludge retention time and short hydraulic retention time (HRT) that occurs in a traditional reactor by integrating two up-flow anaerobic sludge blanket reactors in a vertical series and a gas-driven IC system; therefore, they have ...
Performance, kinetics behaviors and microbial community of internal …
2016年12月1日 · Performance of internal circulation anaerobic reactor (IC) treating wastewater at high organic loading rate (OLR) and role of external hydraulic circulation were evaluated. When the OLR was increased from 2.50 to 18.94 kgCOD/m 3 /d, COD removal decreased to 85% slightly and methane production increased to 4.49 L/L/d with the upflow velocity of ...
Anaerobic Biochemical Reactor - an overview - ScienceDirect
4.2.5 Internal circulation reactor. The internal circulation (IC) reactor is in effect two UASB reactors working in tandem. Hence, an IC reactor contains two sets of 3-phase separation modules, whereas a USBR or EBR reactor only has one separation module.
In this study, the hydrodynamic characteristic of a lab-scale internal circulation (IC) anaerobic reactor was investigated. We found that the gradual Increasing-Size Continuous Stirred-Tank...
Internal circulation (IC) anaerobic reactor is a feasible technology for the treatment of strength wastewater due to the good performance at the high loading rate, good removal efficiency and low operation cost (Wang et al., 2014). Because of its benefits, IC models have been applied in wastewater treatment and indicated good results.
Study on the treatment of corn alcohol wastewater by the internal ...
2023年12月8日 · To comprehensively assess the efficacy of employing the internal circulation (IC) anaerobic reactor for corn alcohol wastewater treatment and investigate its feasibility, this study focused on anaerobic digestion parameters, energy balance, and the composition of the prokaryotic microbial community.
Among them, the Internal Circulation reactor has so far achieved the highest organic loading rate (>30 COD/m3/day) with a regular operational out put of more than 80% COD reduction (5). This paper attempts to explain the major advantages of the Internal Circulation reactor compared to other anaerobic effluent treatment technologies.
