“…Hydrogen can also be produced anaerobically from FW and has several advantages over methane as a fuel. When hydrogen burns, it produces water as the only by-product [9]. Hydrogen has a high energy content 142 MJ/kg compared to methane (55.5 MJ/kg) or gasoline (47.3 MJ/kg) [10].…”

“…In the CSTR, hydrogen-producing bacteria are completely-mixed and the biomass is suspended in the liquor, which already has the same composition as the effluent and it usually don't have the ability to conserve high amount of fermentative biomass because of the mixing stirring. Washing-out of the biomass and the bacteria may occur at short hydraulic retention times (HRTs), thus the hydrogen production rates are considerably restricted [9,14], which push us to maximize the hydrogen production by different technologies.…”

The impact of continuous removal of volatile fatty acids on fermentative hydrogen production from food waste (FW) in a Continuously Stirred Tank Reactor (CSTR) was evaluated. Two experimental phases were conducted, a control phase and one in which volatile fatty acids were removed continuously from the reactor for the first time by electrodialysis (ED). Hydrogen yields were 64.7 cm 3 H 2 /g VS and 227.3 cm 3 H 2 /g VS for control phase, and ED phase respectively. Continuous removal of volatile fatty acids during fermentation not only increased H 2 yields but increased the production of volatile fatty acids (a valuable chemical feedstock) from 0.14 g/g VS to 0.34 g/g VS .

“…High H 2 production rate of 88.73 L H 2 /L d was observed using flex-matala packed bio filters as bacterial carriers. The unique thing about the reactor design was the placement of bio filters inside the reactor, which was installed in the middle of the reactor [40]. A novel modification in CSTR was reported that used continuous multiple tube reactors (CMTR) [5].…”

“…Wastewaters varying from simple sugary industrial effluent to complex lignocellulosic paperboard mill wastewater have been studied for their H 2 production efficiency (Table 1). Wastewaters rich in sugar such as sugarcane vinasse, sugarbeet wastewater and molasses wastewater are reported to produce a high yield of 3.2 mol/mol carbohydrate as well as a low 1.37 mol/mol carbohydrate under varying process parameters [10,17,28,40,43,56]. With wastewaters rich in starch such as rice mill wastewater, corn starch wastewater and cassava wastewater, batch reactors are used in most cases to produce H 2 yields ranging from 1.88 to 1.97 mol/mol sugar [21,22,29,32,57,58].…”

Wastewaters are a rich source of nutrients for microorganisms. However, if left unattended the biodegradation may lead to severe environmental hazards. The wastewaters can thus be utilized for the production of various value added products including bioenergy (H and CH). A number of studies have reported utilization of various wastewaters for energy production. Depending on the nature of the wastewater, different reactor configurations, wastewater and inoculum pretreatments, co-substrate utilizations along with other process parameters have been studied for efficient product formation. Only a few studies have reported sequential utilization of wastewaters for H and CH production despite its huge potential for complete waste degradation.

“…They exhibit lots of advantages as compared with activated sludge process such as stability and long retention time of microorganisms which enable removal of recalcitrant pollutants (Guo et al, 2009). The hydraulic mixing regime in a fixed-bed bioreactor is less turbulent compared with the Continuous Stirred Tank Reactor (CSTR) (Chu et al, 2016). However, the physicochemical properties of the packing material also strongly influence hydrodynamics and bioavailability of the contaminant for degradation (Iffat et al, 2015;Ji et al, 2015;Krüner and Rosenthal, 1983;Sharvelle et al, 2008;Wang et al, 2006;Yue et al, 2009).…”

The discharge of colored textile wastewaters containing dyes with different chemical characteristics into the receiving streams is a problem for toxicological, ecological and also esthetical reasons. Most of dyes are stable, and not easily degradable by the conventional treatment methods, so removal of dyes from the textile effluents is a major problem. This study aimed to investigate color removal efficiency of two aerobic filter column reactors operated as sequencing as biological and chemical treatment steps. Biological column reactor (BR) filled with basaltic lava (Scoria) as supporting media for microorganisms, and second column reactor (CR) was filled with lime and textile fly ash mixture (1:3, w/w) used as chemical treatment step especially for phosphate and color removal. The reactors were operated at batch mode to investigate the effect of hydraulic retention times (HRT), aeration time and initial dye concentration (Everzol Blue BB) on treatment efficiencies. The results of the study showed that this system has quite high removal efficiencies for soluble organics and nutrients from wastewater. COD, TOC, NH4-N and PO4-P removal rates were obtained as 94.2 %, 94.8 %, 84.7 % and 97.5% in HRT of 24 h, respectively. In addition, this two-step treatment system reached to quite high color removal efficiencies of 96.4 % Pt/Co, 96.4 % DFZ-436 nm, 99.5 % DFZ-525 nm, and 99.8 % DFZ-620 in initial dye concentration of 800 ppm.
