“…There is no doubt that the initial pH of an organic solution in this case (or a suspension or surface water or even wastewater) is the main parameter of the performance of the coagulation process [45][46][47]. To study the impact of the initial pH on the elimination of dyes, we varied it in a wide range from 2 to 12 while keeping constant the two optimal doses of the coagulants.…”

Coagulation process is largely applied for dye removal from textile wastewater treatment. This research aims to focus on implied mechanisms through coagulation of such wastewater. In this work, jar tests are performed to assess the coagulation process as a technique to treat synthetic solutions containing two textile dyes: BF cibacete blue (CB) and red solophenyle 3BL (RS). The effects of operational parameters such as coagulant type (FeCl 3 and Al 2 (SO 4) 3. 18H 2 O (alum)) and dose, initial pH, and dye concentration are studied. For a fixed 15 mg/L concentration of the two dyes, the FeCl 3 optimal doses are found to 80 and 20 mg/L for RS and CB with removal rates of 65 and 89%, respectively. Regarding alum, discoloration is achieved at 44 and 77% for CB and RS with optimal doses of 80 and 40 mg/L, respectively. Similar efficiency trends are also obtained for a 50 mg/L concentration of the two dyes. The involved coagulation mechanisms are: charge neutralization followed by precipitation of the insoluble dye-coagulant complexes, and their adsorption into the Al or Fe hydroxides. It would be interesting to follow a real effluent application on the textile industry possibly containing the two dyes tested in this work.

“…The production methods of hydrogen energy mainly include hydrogen production from electrolyzed water, hydrogen production from fossil fuels, and hydrogen production from biological processes. Compared with the other two hydrogen production methods, biological hydrogen production is a better hydrogen production method, because biological hydrogen production can be performed at normal temperature and pressure, low energy input, high efficiency, and biological hydrogen production is green and environmentally friendly [5][6][7][8][9][10][11]. Biological hydrogen production can use a wide range of substrates, such as glucose, xylose, kitchen waste and agricultural waste [12][13][14].…”

2020) Statistical optimization of simultaneous saccharification fermentative hydrogen production from corn stover, Bioengineered, 11:1, 428-438, ABSTRACT Corn stovers are rich in carbohydrates and can be used by anaerobic bacteria to produce hydrogen by fermentation. In the present study, using hydrogen production as the main experimental index, the effect of different influential factors on hydrogen production from corn stover saccharification and fermentation was studied, using the response surface method BBD model. The significance of interactions between different influential factors on hydrogen production by simultaneous saccharification and fermentation of corn stover material were investigated and optimized. Results showed that there were several factors affecting simultaneous saccharification fermentative hydrogen production from corn stover, including substrate concentration, inoculation amount, pH value and enzyme concentration. In linear terms, substrate concentration had the greatest influence on hydrogen production by anaerobic simultaneous saccharification and fermentation. In terms of multi-factor interactions, the interaction between pH and enzyme concentration was the most significant. The optimal hydrogen production conditions established from the BBD model were as follows: substrate concentration of 25 mg/mL, inoculation amount proportion of 32.62%, initial pH value of 6.50 and enzyme concentration of 172.08 mg/g, resulting in the maximum hydrogen production of 55.29 mL/g TS. The actual maximum hydrogen production reached 56.66 mL/g TS, with these experimental results consistent with the predicted value established from equation fitting. This study provides a reference for hydrogen production by anaerobic synchronous saccharification fermentation using corn stover as substrate and lays a foundation and provides technical support for the industrialization of biological hydrogen production using corn stover as substrate.

“…The combustion of hydrogen liberates water molecules and energy instead of greenhouse gases [ 1 , 4 ]. Even though hydrogen fuel is beneficial but still is produced via high energy intensive conventional methods like water electrolysis and steam reforming of fossil fuels [ 5 ]. Alternating the hydrogen production source and method will improvise the quality and cost effectivity of hydrogen fuel [ 5 ].…”
