“…Therefore, our result showed that moderate acidogenesis could be achieved during the acid fermentation under HRT of 4 days by suppressing the methanogenesis from conversion of the VFAs. Additionally, the complimented structure of the ABR type-acid fermentation reactor contributed non-soluble large molecular organics, hydrolyzed to soluble organics by exoenzyme in the reactor, which induced more VFA production from total organic matter in the influent [28]. The average VFA concentration relative to the VSS was 168 mgCOD/gVSS and the specific VFA production rate was 0.074 mgVFAs/mgVSS/day.…”

Abstract:In this study, an anaerobic baffled reactor (ABR), combined with a post denitrification process, was applied to treat primary sludge from a municipal wastewater treatment plant and wastewater with a high concentration of nitrate. The production of volatile fatty acids (VFAs) was maximized with a short hydraulic retention time in the acid fermentation of the ABR process, and then the produced VFAs were supplied as an external carbon source for the post denitrification process. The laboratory scale experiment was operated for 160 days to evaluate the VFAs' production rate, sludge reduction in the ABR type-acid fermentation process, and the specific denitrification rate of the post denitrification process. As results, the overall removal rate of total chemical oxygen demand (TCOD), total suspended solids (TSS), and total nitrogen (TN) were found to be 97%, 92%, 73%, respectively, when considering the influent into ABR type-acid fermentation and effluent from post denitrification. We observed the specific VFAs production rate of 0.074 gVFAs/gVSS/day for the ABR type-acid fermentation, and an average specific denitrification rate of 0.166 gNO 3´-N/gVSS/day for the post denitrification. Consequently, we observed that a high production of VFAs from a primary sludge, using application of the ABR type acid fermentation process and the produced VFAs were then successfully utilized as an external carbon source for the post denitrification process, with a high removal rate of nitrogen.

“…With time, the size of these granules increased, particularly in the earlier compartments (Krishna et al, 2007;Ji et al, 2009). It has also been reported that the inoculated granules in the first compartment appeared to be broken up and replaced by non-granular fluffy sludge while treating whisky distillery wastewater with granular-bed anaerobic baffled reactor (GRABBR).…”

“…As the above mentioned, when the ABR was applied to treat refractory wastewaters, the reactors achieve successful start-up, respectively: it took 60 days to achieve a start-up for treating PNP-containing waste-water; the Liu et al 1539 reactor achieved prompt start-up while treating SO 4 2--containing wastewater; the reactor took 164 days to achieve a successful start-up while treating heavy oil produced water (Kuscu and Sponza, 2005;Vossoughi et al, 2003;Ji et al, 2009).…”

With the increasing deterioration of world water resources, configuring a technical and economic viable wastewater treatment and recycle technology to satisfying the increasing complexity of wastewater and stringent environmental regulation has been a great challenge over the past decades. Developing reliable technologies for wastewater treatment is of urgent importance. In recent years, anaerobic baffled reactor (ABR) treating wastewaters effectively, have received considerable attention in the literature. This paper reviews the development and application, performance and characteristics, modeling of the ABR for wastewater treatment and the combination of ABR with other processes during the last decade. This paper provides a critical review on the ABR for treatment of refractory wastewaters. It was indicated that ABR had become a promising alternative for wastewaters treatment with great further development potential.

“…Although anaerobic digestion of saline wastewaters such as effluents from tannery industries (Lefebvre et al, 2006), seafood-processing (Omil et al, 1995) and oil and gas production (Ji et al, 2009) have been studied, solutions to the problem of inhibitory high sodium salts are still limited. One way of tackling the sodium salts problem, is by allowing the anaerobic sludge to acclimate to high sodium concentrations (Vyrides et al, 2009), but this technique requires time for the methanogens to adapt to the saline conditions which in turn results in a prolonged period 3 before the anaerobic reactor can achieve its full-loading capacity.…”

This is a PDF file of an unedited manuscript that has been accepted for publication. As a service to our customers we are providing this early version of the manuscript. The manuscript will undergo copyediting, typesetting, and review of the resulting proof before it is published in its final form. Please note that during the production process errors may be discovered which could affect the content, and all legal disclaimers that apply to the journal pertain. AbstractSodium toxicity is a common problem causing inhibition of anaerobic digestion, and digesters treating highly concentrated wastes, such as food and municipal solid waste, and concentrated animal manure, are likely to suffer from partial or complete inhibition of methane -producing consortia, including methanogens. When grass clippings were added at the onset of anaerobic digestion of acetate containing a sodium concentration of 7.8 g Na + /L, a total methane production about 8 L/L was obtained, whereas no methane was produced in the absence of grass leaves. In an attempt to narrow down which components of grass leaves caused decrease of sodium toxicity, different hypotheses were tested. Results revealed that betaine could be a significant compound in grass leaves causing reduction to sodium inhibition.
