“…Table 3 shows the numerical index of comparison for the parameters found in Al Amerat landfill leachate, with landfill phases. Results from this comparative study using different parameters, is found to have variations within the degradation stage of the landfill ( Ehrig, 2005 ; García-Sánchez et al, 2018 ). All values in Table 3 are in mg/l except pH and BOD/COD.…”

“…The maximum COD removal percentage was found to be 68% at the highest pH, and the highest intensity used, with shaking at 400 rpm as shown in Figure 2 . Previous studies on bio-hydrogen production using photo-fermentation have shown COD removal efficiency of 77%, when the light intensity was higher, which is due to the use of short-chain organic acid ( García-Sánchez et al, 2018 ). Hence, light intensity has a direct effect on the COD removal.…”

Recently, it has become imperative to find new sustainable and renewable sources of energy, in order to avoid dependence on non-renewable traditional energy resources. This would help to overcome the depleting of natural resources for energy production. Hydrogen gas production using biological processes is one of the most attractive solutions in this regard, due to its high energy content and ecofriendly nature. Production of hydrogen using single photo-fermentation process and landfill leachate as substrate was carried out in this paper, by utilizing batch bio-reactor and anaerobic conditions. The pH value and temperature, play an essential role in a bio-hydrogen production process. Thus, in this study, the pH values considered were 6, 6.5, and 7.2, respectively, at a controlled temperature of 37 ± 1°C. This study investigated various schemes that have the possibility of producing hydrogen using; landfill leachate alone, with leachate and addition of inoculum such as sewage sludge, and with substrate such as sucrose and glucose. All experiments were conducted with and without mixing, for effective comparative study. Heat and pH pretreatment were applied in each experiment with the objectives of decreasing the activities of methane-producing bacteria and enhancing the activities of hydrogen-producing bacteria. The hydraulic retention time used in this study was 48 h, in order to obtain optimal performance of the schemes employed. Analysis of liquid leachate was performed for each experiment, and based on the obtained results, the maximum yield of hydrogen produced was 5,754 ml H2/L, with a medium pH scale of 6.0, fermentation temperature of 37 ± 1°C and constant mixing speed of 100 rpm.

“…For cost reduction of temperature control during summer, Rhodobacter capsulatus-PK was found as a good candidate for photofermentive bio-H 2 production. García-Sánchez et al [75] used Rhodopseudomonas pseudopalustris to produce H 2 by tequila vinasses (VT) photofermentation. Compared with synthetic medium, they found a double H 2 yield with VT. With the replacement of H 2 by N 2 compared with unchanged headspace, three-time growth was seen in R. pseudopalustris up to 4.5 g/L, and the H 2 yield also increased to 860 mL H 2 /L.…”

The ever-increasing world energy demand drives the need for new and sustainable renewable fuel to mitigate problems associated with greenhouse gas emissions such as climate change. This helps in the development toward decarbonisation. Thus, in recent years, hydrogen has been seen as a promising candidate in global renewable energy agendas, where the production of biohydrogen gains more attention compared with fossil-based hydrogen. In this review, biohydrogen production using organic waste materials through fermentation, biophotolysis, microbial electrolysis cell and gasification are discussed and analysed from a technological perspective. The main focus herein is to summarise and criticise through bibliometric analysis and put forward the guidelines for the potential future routes of biohydrogen production from biomass and especially organic waste materials. This research review claims that substantial efforts currently and, in the future, should focus on biohydrogen production from integrated technology of processes of (i) dark and photofermentation, (ii) microbial electrolysis cell (MEC) and (iii) gasification of combined different biowastes. Furthermore, bibliometric mapping shows that hydrogen production from biomethanol and the modelling process are growing areas in the biohydrogen research that lead to zero-carbon energy soon.

“…In the state of Jalisco, México, this has been a common practice. Unfortunately, even today vinasses are still discharged by small and medium-sized Tequila producers into water bodies, or used in crops with the risk that this implies for aquatic life due to the high content of organic matter and color [7,8]. Table 1 shows the composition of the Cachaça and Tequila vinasses [9,10].…”

Regulation of Hydrogen Peroxide Dosage in a Heterogeneous Photo-Fenton Process

et al. 2021

In this work, a classical linear control approach for the peroxide (H2O2) dosage in a photo-Fenton process is presented as a suitable solution for improving the efficiency in the treatment of recalcitrant organic compounds that cannot be degraded by classical wastewater treatment processes like anaerobic digestion. Experiments were carried out to degrade Lignin, Melanoidin, and Gallic acid, which are typical recalcitrant organic compounds present in some kinds of effluents such as vinasses from the Tequila and Cachaça industries. Experiments were carried in Open-Loop mode for obtaining the degradation model for the three compounds in the form of a Transfer Function, and in Closed-Loop mode for controlling the concentration of each compound. First-order Transfer Functions were obtained using the reaction curve method, and then, based on these models, the parameters of Proportional Integral controllers were calculated using the direct synthesis method. In the Closed-Loop experiments, the Total Organic Carbon removal was 39% for lignin, 7% for melanoidin, and 29% for Gallic acid, which were greater than those obtained in the Open-Loop experiments.
