“…The dynamics of changes in the dehydrogenase activity during the anaerobic digestion of sewage sludge had a different nature (Figure 12)-there was a successive decrease in the DHA in the experimental variants. Dehydrogenases are intracellular enzymes, which are regarded as biochemical indicators of the metabolic activity of microorganisms [49,50]. According to reference publications [51], the DHA is positively correlated with the content of organic matter in the substrate and the biomass of microorganisms.…”

This study compares the effects of pure kraft lignin and the kraft lignin/silica system (1:4 by weight). The comparative analysis of the physicochemical properties of both carriers showed that the kraft lignin/silica system was characterised by better properties. The experiment conducted in the study involved continuous anaerobic digestion under mesophilic conditions. Three samples were degraded in the following order: (i) sewage sludge (SS), (ii) SS with the addition of kraft lignin, and (iii) SS with the addition of the kraft lignin/silica system. A quantitative analysis of the digestate samples was carried out by means of in situ fluorescence. It showed more intense proliferation of microorganisms in the SS + kraft lignin/silica variant than in the sample with pure kraft lignin. The highest amount of biogas was obtained in the SS + kraft lignin/silica variant (689 m3 Mg−1 VS, including 413 m3 Mg−1 VS of methane; VS—volatile solids). There were comparable amounts of biogas in the SS variant (526 m3 Mg−1 VS of biogas, including 51% of methane) and the SS + kraft lignin variant (586 m3 Mg−1 VS of biogas, including 54% of methane). The research clearly showed that the material with a high share of silica was an effective cell carrier.

“…Petroleum products are the most commonly used materials that are processed from crude oil in an oil refinery. Petroleum products or by-products are generally used in different industries, such as car and airplanes manufacturing (1,2). However, the use of petroleum compounds has been associated with environmental pollution that can be due to its toxicity, and it can cause soil and air pollution (3,4).…”

Background: Soil remediation is one the important problem in environmental studies. Thus, this research was conducted to evaluate the effect of organic chelates and gibberellic acid (GA 3 ) on the degradation of crude oil in the soil co-contaminated with Ni and crude oil under canola cultivation. Methods: For treatments, HEDTA and NTA chelates at rates of 0 and 2.5 mmol/kg soil and foliar GA 3 (0 (GA 3 (-) and 0.05 (GA 3 (+) mM) were used. In addition, the soil was polluted with Ni (0 and 100 mg Ni/kg soil) and crude oil at rates of 0, 2, and 4% (W/W). The plant used in this experiment was canola. The concentration of Ni in soil and plant was measured using atomic absorption spectroscopy (AAS). The concentration of total petroleum hydrocarbon (TPH) was measured using GC-mass. The mean differences were calculated according to the least significant difference (LSD) test. Results: The greatest degradation of crude oil belonged to the non-Ni-polluted soil under cultivation of GA 3 -treated plant, while the lowest one was observed in the soil received the greatest level of HEDTA and NTA chelates. Applying 0.05 mM GA 3 foliar significantly increased the degradation of crude oil in soil and Ni in plant shoot by 12.1 and 8.3%, respectively. In addition, soil microbial respiration was also increased by 11.3%. Conclusion: HEDTA, NTA, and GA 3 had a significant effect on the Ni phytoremediation efficiency and degradation of crude oil in soil that is a positive point in environmental pollution. However, the role of soil physico-chemical properties on the phytoremediation efficiency cannot be ignored. Citation: Baghaie AH, Daliri A.

“…The refining process for crude oil uses 1.6 gallons of water per gallon of crude oil (Coelho et al 2006), which is responsible for a major share of aquatic pollution. To treat oily sludge and effluents of refining process, several techniques and pretreatments including chemical oxidation, centrifugation, adsorption, photo-Fenton, biological, and so forth were introduced (Diya'uddeen et al 2011;Aljuboury et al 2015;Siddique et al 2015;Choromanski et al 2016;Haak et al 2016;Rastegar et al 2011;Roy et al 2016). The liquid part of residuals is oil refinery wastewater that is considerable and huge aquatic mixture.…”

To survey the anaerobic co-digestion (AcoD) of oil refinery wastewater (ORWW) with sugarcane bagasse (SCB), six different AcoD compositions were evaluated. Results including cumulative biogas production (BGP), bio-methane contents (BMP), and soluble chemical oxygen demand (CODs) removal rate were experimentally obtained. The negligible BGP by ORWW mono-digestion revealed that it could not support any microbial activity. However, increasing the SCB ratio in the AcoD compositions led to increased BGP and BMP contents. By considering the statistical test (LSD0.05) results for the kinetic parameters, the 1:4 ratio treatment was the most favorable AcoD composition. Moreover, the CODs removal rate from 22.34 ± 1.63% for the SCB mono-digestion was improved to 49.67 ± 0.38% for the 2:3 AcoD composition and BMP content from 54.12 ± 0.45% for the SCB mono-digestion was enhanced to 62.69 ± 1.22% for the 1:4 AcoD composition with 20% lower SCB usage. The results computed by applying three mathematical models determined that the modified Gompertz model provided the best fit. Also, implementing artificial neural network algorithms to model the BGP data revealed that the Back Propagation algorithm was the best suited for the experimental BGP data, with 0.6444 and 0.9658 for MSE and R2, respectively.
