Co-MOF was synthesized via solvothermal technique and further characterized using X-ray diffraction (XRD), Fourier transform infrared spectros-copy (FTIR), and scanning electron microscopy (SEM). The characterization results of material confirm the formation of MOF structure. The adsorption kinetics, isotherms, thermodynamics, as well as isosteric heat of adsorption were also investigated by obtaining experimental adsorption data through batch experimentation. Optimum adsorption uptake of ~91 mg g –1 was attained at pH 6 and 305 K. Regression analysis of experimental results revealed that adsorption kinetics follows a pseudo-second-order kinetic model, and adsorption can reach equilibrium at ~20 min. Adsorption isotherm data can be well fitted with Koble Corrigan isotherm. Thermodynamic parameters demonstrated that the adsorption of humic acid is a spontaneous, endothermic, and physical process, while isosteric heat evaluations revealed the heterogeneous nature of the adsorbent. Overall, the Co-MOF was a promising choice to adsorb humic acid from water.","PeriodicalId":9765,"journal":{"name":"Chemical and Biochemical Engineering Quarterly","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2022-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48905066","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The gasification process was preceded by drying the SS in an integrated tubular rotating structure with built-in worm conveyors, to increase the dry matter (DM) content in the SS (> 90 wt.%). The released hydrogen-rich syngas from the gasification process of SS had low heating value (LHV) of approximately 8.83 MJ N –1 m –3 (equal to 2.45 kWh N –1 m –3 ) due to the high content of combustible gases H 2 (41.5 vol.%) and CH 4 (3.2 vol.%). Also investigated was the incorporation of sewage sludge ash (SSA) generated in the process of gasification as a partial substitute for clay in the production of clay bricks. Amounts of 5 wt.%, 10 wt.%, 20 wt.% of clay were replaced by SSA. By incorporating SSA at 5 wt.%, the new brick product achieved 4.5 % higher compressive strength compared to the control brick.","PeriodicalId":9765,"journal":{"name":"Chemical and Biochemical Engineering Quarterly","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2022-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44026158","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Characterization studies performed on RSAC have revealed that RSAC is a mesoporous adsorbent with significant affinity towards 2-chlorophenol (2-CP). The optimal values for process parameters were investigated via experimental runs. The optimal values of process parameters such as RSAC dose, pH of 2-CP solution, contact time, and temperature were found to be; 1.25 g L –1 , 8, 125 min, and 303 K, respectively. The Langmuir isotherm and pseu-do-first-order kinetics models were found to be in good agreement with the experimental data for this adsorption system. The adsorption thermodynamics studies have revealed that the adsorption of 2-CP onto RSAC is exothermic and spontaneous. Regeneration studies of RSAC using hydrogen peroxide have revealed that RSAC was effectively regenerated for four consecutive cycles. This research has proved the potential of RSAC for abating 2-CP from aqueous solutions.","PeriodicalId":9765,"journal":{"name":"Chemical and Biochemical Engineering Quarterly","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2022-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48763068","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, mixed bacterial cells were alternatively immobilized in sodium alginate (SA) and in sodium alginate-polyvinyl alcohol (SA – PVA) for biodegradation of sodium dodecyl sulfate (SDS). Synthetically prepared SDS-bearing aqueous solution (SWW), as well as actual automobile service station wastewater (AWW) and laundry wastewater (LWW) were used. The results revealed that high removal efficiencies were achieved after 48 h for both types of beads. When SDS concentration in SWW increased from 10 to 1000 mg L –1 , SDS degradation using both types of beads were decreased from 99.71 % to 85.12 % using SA beads, and from 99.63 % to 83.29 % using SA-PVA beads. The removal efficiency of SDS in the actual (AWW) were 94.91 % and 93.82 % using SA beads and SA-PVA beads, respectively. While, for SDS-bearing laundry (LWW), the removal efficiencies were 94.39 % and 92.04 % using SA beads and SA-PVA beads, respectively. No decline in the biodegradation capacity of immobilized consortium was noted over its recycling and reuse. Both hydrogel matrices lasted for up to five cycles in the actual wastewaters. These promising results confirmed the validity of using immobilized mixed cells as an efficient and cost-effective approach for SDS biodegradation in real industrial wastewaters.","PeriodicalId":9765,"journal":{"name":"Chemical and Biochemical Engineering Quarterly","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2022-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44195058","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Various extractants viz. tri-n-butyl phosphate, trioctylamine, and trioctylmethylammonium chloride along with i-octanol as a diluent were used. The extent of separation was investigated and various performance parameters like extraction efficiency, distribution coefficient, equilibrium complexation constant, and loading ratio were estimated. The number of transfer units, diffusivity, and mass transfer considerations were also discussed in the reactive separation system.

Tests carried out in an airlift bioreactor with B. licheniformis showed a maximum productivity of 0.789 g L–1 h–1 and a yield of 0.4 g g–1. Different soybean cultivars from the 2015 and 2016 crops were used in the SSF. The BRS 1001IPRO cultivar, from the 2016 crop, showed the highest production, i.e., 1.2 g L–1 of γ-PGA. This cultivar was subjected to different levels of milling (fine, intermediate and coarse). Coarsely milled grains increased γ-PGA production to 2.7 g L–1. Moreover, coarse milling made the internal nutrients of the grains available for fermentation and this particle size did not compromise aeration during fermentation.","PeriodicalId":9765,"journal":{"name":"Chemical and Biochemical Engineering Quarterly","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2021-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45058887","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
