Sludge blanket reactors: Anaerobic sludge blanket reactors send wastewater through a floating blanket-like layer of sludge. In this study results from two plants with a 430 and 511 m3-AFR, respectively, are presented. 359-363. This is a completely mixed reactor, equipped with an agitation system to prevent sludge settling or flotation. Five batch reactors (10 L working volume) were adopted for the test of anaerobic digestion parameters, as illustrated in Fig.1. ClearFAR, with an effective sludge retention system, converts organic compounds into valuable biogas. This research utilized computational fluid dynamic simulations to evaluate the effect of the headspace pressure on the granular sludge flotation, using an operating anaerobic upflow reactor (AUR) at a cassava starch factory as the model reactor. Anaerobic sludge blanket reactors Sludge blanket reactors are a type of anaerobic treatment where wastewater is passed through a free-floating “blanket” of suspended sludge particles. It is a cylindrical column fitted with a packing support near its bottom. Also, an internal DUREX In this study results from two plants with a 500 m3-AFR are presented. Zhuo Zeng, Ping Zheng, Meng Zhang, Abbas Ghulam, Performance and working mechanism of a novel anaerobic self-flotation reactor for treating wastewater with high suspended solids, Environmental Science and Pollution Research, 10.1007/s11356-019-05885-6, (2019). The use of a DAF system for polishing anaerobic effluents would provide another important feature to the treatment plant. ... which prevents flotation effects and, consequently, floating layers. Operation performance and granule characterization of upflow anaerobic sludge blanket (UASB) reactor treating wastewater with starch as the sole carbon source Bioresour Technol . ANAEROBIC DIGESTION Anaerobic digestion is a collection of processes by which microorganisms break down biodegradable material in the absence of oxygen. Training Material on Anaerobic Wastewater Treatment Version 3, December 16th, 2008 martin.wafler@seecon.ch Permission is granted for reproduction … Up flow anaerobic sludge blanket technology also known as UASB reactor is a form of anaerobic digester which used in wastewater treatment. Although both reactors were operated in fill-and-draw (batch) mode, effluent from ECF was fed to FBR in order to remove the … In the ANAMIX™ reactor portion of the FLOTAMET™, the actual anaerobic treatment takes place. Anaerobic Baffled Reactor: This design, which is very recent, was evolved by Bachmann et al. IC Anaerobic Reactor (Internal Circulation Reactor) Application Internal circulation reactors are used in the treatment of highly concentrated organic wastewater, such as wastewater from potato processing, endive processing, beer production, citric acid and paper production, starch wastewater, ethyl alcohol sewage and other light industrial food. In the reactor a flotation unit is integrated to retain the sludge. 2015 Mar;180:264-73. doi: 10.1016/j.biortech.2015.01.010. BIOPAQ-Anaerobic Flotation Reactor or BIOPAQ®AFR. Anaerobic Filter Reactor: An anaerobic filter reactor is basically a packed bed. Anaerobic Flotation Reactor AFR. The packing support may be either a perforated sheet or a grid having openings smaller than the packings. A series operation of electrocoagulation/flotation (ECF) and fluidized bed anaerobic reactor (FBR) was conducted to treat tannery wastewater. Dissolved and suspended organic matter is largely degraded by anaerobic bacteria (sludge) and converted into biogas. (1982) at Stanford University. Anaerobic digestion system that offers very stable, robust wastewater treatment and biogas generation under a wide range of operating conditions. UASB reactor is a methane-producing digester, which uses an anaerobicprocess and forming a blanket of granular sludge and is processed by the anaerobic … This anaerobic flotation reactor (AFR), with an effective sludge retention system, is an all-in-one system that converts organic compounds into valuable biogas. Fat-containing food waste can be effectively treated in a new type of reactor, the so-called BIOPAQ-Anaerobic Flotation Reactor or BIOPAQ® anaerobic flotation reactor (AFR).
