Subject: Experimental Study of Biological Nitrate Removal Performance in Semi-Arid Regions: Effects of Woodchips and Hydraulic Retention Times
Keywords: Agricultural wastewater, biological process, nitrate reduction, Urmia lake basin
Abstract: Increasing fertilizer application to compensate for nutrient deficiency and ensure food security has caused leaching of more nitrate through sub-surface drainage and the spread of eutrophication in aquatic ecosystems. Woodchip bioreactors are a well-known method for removing nitrate from agricultural effluents. However, there is not enough knowledge about the performance of native woodchips in semi-arid ecosystems. 9 treatments, including 3 woodchips and 3 hydraulic retention times (HRTs) of 5, 12 and 24 hr were studied in 3 repetitions. Studied woodchips, walnut, beech and poplar were chosen from native trees of Urmia lake basin, known as a semi-arid region. The results disclosed that the HRT and woodchip significantly affected the nitrate removal rate (P<0.05). Walnut and beech woodchips had the highest and lowest nitrate reduction capability, respectively. The study showed an increase of about 16% in the nitrate removal efficiency in all woodchips due to an increase in the HRT from 5 to 12 hr. There were no significant differences between the HRTs of 12 and 24 hr (P>0.05). The results of this study confirm the desirable performance of walnut woodchip and 12 hr HRT in nitrate removal under semi-arid conditions.

Subject: A Study on Degradation of 1-Ethyl-3-Methylimidazolium Chloride and 1-Butyl-3-Methylimidazolium Chloride by Fenton’s Process and Optimization using Response Surface Methodology
Keywords: Imidazolium-based ionic liquids, Degradation, Fenton’s oxidation, Central composite design, Response surface methodology
Abstract: In this study, the process optimization was carried out by the application of response surface methodology (RSM) for the degradation of ionic liquids, namely 1-ethyl-3-methylimidazolium chloride (EMIMCl) and 1-butyl-3-methylimidazolium chloride (BMIMCl) in an aqueous solution using Fenton’s oxidation process. Experiments were designed using central composite design (CCD) of response surface methodology (RSM). The oxidant dosage (H2O2), the dosage of catalyst (Fe+2) and pH were selected as three independent input operating variables. The goodness of fit of the model was measured using the regression coefficient (R2) and the adjusted regression coefficient (R2adj). The R2 values of the model were 0.9564 and 0.9270 for EMIMCl and BMIMCl, respectively whereas the R2adj values were 0.9891 and 0.9817 for EMIMCl and BMIMCl, respectively. These values indicate a good fit for the model. An average maximum TOC degradation of EMIMCl (83.68%) and BMIMCl (73.54%) were calculated. The good agreement between the predicted values and the experimental values confirms the validity of the model for simulating the degradation of EMIMCl and BMIMCl by the Fenton oxidation process.

Abstract: Noise pollution is one of the major problems facing the modern world at large due to economic growth, industrialization and uncontrolled urbanization. Exposure to high noise pollution levels has physiological (auditory) and psychological effects. The project aims to determine variations in noise level and pollution produced within the Oja Oba area in Ibadan, Oyo state, Nigeria. The environmental equivalent noise levels (Leq) were measured at 12 randomly selected spots within Oja Oba market in the morning and afternoon between September and October 2020 using an SW-524 LCD digital sound level meter. The meter was held at about 1.5 m above ground levels and 3 m from the noise source around each spot for 1/4 of an hour before readings were taken to ensure good area coverage, stability and uniformity in measurement. The average noise pollution level (Lnp) was calculated using a standard equation. The standard deviation of disease and area affected by noise pollution were 0.2 and 0.3589, respectively. The equivalent noise level in the market at the 12 selected points for working days and weekends ranged between 70-98 and 68-106 dBA, respectively. The average noise pollution level in the market varied from 87-128 dBA. These equivalent noise levels and average noise pollution for the Oja Oba market were computed. The obtained data can serve as baseline information for noise pollution modelling and control.

Subject: Bioleaching of Copper from Auto-Switch and Inverter Printed Circuit Board using Microbial Metabolites
Keywords: Waste printed circuit boards, Auto-switch, Inverter, Bioleaching, Oxidising iron bacteria, Consortium, Copper
Abstract: Electronic equipment commonly known as e-waste is the fastest-growing solid waste in the world. E-waste is nowadays preferentially used for the recovery of metals from printed circuit boards (PCBs). The PCB is a significant part of all electronic waste, and it is a potential source of different metals, thus known as an urban mine. The study aimed to enhance the extraction of copper from pulverised waste printed circuit boards (WPCBs) using an iron-oxidising consortium from the inverter and auto-switch WPCBs. Microbial leaching is based mainly on the potential of microorganisms to generate lixiviants that mobilise metals from PCBs. Iron-oxidising bacteria generate ferric iron and protons that extract several metals in the aqueous phase. In this study, optimisation of various parameters was done. Optimised conditions for inverter WPCBs and auto-switch WPCBs showed more than 95% extraction of copper at pH 1.8 to 2.0, ferrous iron concentration from 6% to 8% and pulp density of 10%.

Abstract: The study of groundwater quality in Lingasugur taluk of Raichur district has resulted in a large hydrochemistry data which is here simplified with the water quality index (WQI) for better understanding of the overall quality parameters alongwith the categorized areal extent. A total of 116 groundwater samples have been collected in each season of pre-monsoon and post-monsoon to study the hydrochemistry as well as seasonal variation in the physico-chemical parameters. The collected groundwater samples were analyzed for physical characteristics, such as pH, EC and TDS alongwith the chemical major ions, like Ca2+, Mg2+, Na+, K+, Cl–, SO42-, HCO3–, CO32-, NO3– and F–. The correlation analysis has been carried out to understand the geochemical processing controlling groundwater geochemistry. The water quality index (WQI) values were categorized into six classes and mentioned the statistical data accordingly. The result suggests that the overall quality of the study area is suitable for irrigation and industrial use whereas only 6% and 4% of the water samples are suitable for drinking purposes during pre-monsoon and post-monsoon seasons, respectively. This study illustrates the usefulness of WQI and understanding the water quality along with the extent of the contamination.

Subject: Application of Mitscherlich-Bray Equation for Fertilizer Use in Barley Production in the Wolaita of Southern Ethiopia
Keywords: Barley, Nitrogen, Phosphorus, Potassium, Total value cost ratio
Abstract: The experiments were intended at three locations to formulate different levels of NPK fertilizers recommendations for barley based on the Mitscherlich-Bray equation at the Wolaita zone in southern Ethiopia. The experiments were laid out in randomized complete block design (RCBD) with factorial arrangements applying NPK with three replications. Treatments were levels of N (0.23 and 46, P, 0, 10, 20 and 30 and K, 0, 25 and 50 kg/ha) in all possible combinations. The theoretical maximum yield of barley was calculated by plotting log y vs 1/x (amount of nutrients applied). Fertilizer recommendations for various soil fertility levels and yield targets were developed and their validities were tested by conducting three field verification trials on the same soils. The results showed that although the general recommended fertilizer dose resulted in the highest yield of barley at all the locations, total value cost ratio and net revenue were lowest with this fertilizer treatment and maximum yield treatment was superior in terms of the economics of fertilizer. The model considers the interactions of N, P and K and soil properties adjusted potential yield of the region, which predicts crop yields from chemical soil characteristics, as an indicator of soil fertility.

Abstract: Removal of colour during the treatment of wastewater has always urged the scientific community to create sustainable, cost-saving and novel methods in recent times. The present study aims to study the feasibility of the removal of Rose Bengal dye from an aqueous solution through an electrolytic oxidation reaction. Zinc and carbon cathodes are placed in an electrolytic solution containing Fenton’s reagent and Rose Bengal dye ranging from concentrations of 4 to 12 ppm. The operational parameters like voltage (4.8 V, 6 V and 7.2 V), catalyst concentration (0.18 mM, 0.27 mM and 0.36 mM) and electrode selection were varied to determine the maximum removal efficiency. The combination of 4.8 V – 0.36 mM – 4 ppm presented a maximum removal efficiency of 92.97% for zinc electrode while the combination of 7.2 V – 0.36 mM – 4 ppm showed maximum removal of 94.99% for carbon electrode in Rose Bengal removal from aqueous solution. The results from the laboratory studies were interpreted with a variance analysis through ANOVA and regression equations with a desirability factor of more than 94% were obtained.

Abstract: Stubble burning and its resultant pollutants have adversely affected the environment and posed serious health hazards. It is very important to understand the situation from the farmer’s perspective and from the perspective of conserving the environment. In the present study, a critical analysis of stubble burning and its effects on the neighbouring city of Delhi has been done with the help of satellite imagery and simultaneously analysing the air quality index. The effect of pollutant dispersion on neighbouring areas has been studied at the time point when stubble burning takes place and over the following time intervals in the adjoining area. Furthermore, this study conducts an economic analysis of biogas plant establishment, biogas and biofertilizer generation from stubble and its sale. Thus, this study provides an opportunity analysis on how the stubble can be put to better use to produce utilizable cooking gas and fertilisers, which can directly benefit farmers, besides being economically and environmentally rewarding. The paper concludes with policy-related suggestions including setting up of corporative societies including the farmers as participants.

Subject: Thermochemical Valourization of Corn Cob Biomass Waste: Thermogravimetric Analysis and Pyrolysis Studies
Keywords: Corn cob biomass, Thermogravimetric analysis, Pyrolysis, Bio-oil, Bio-char
Abstract: In present study, decomposition analysis and pyrolysis studies of corn cob biomass waste were carried out using thermogravimetric analysis (TGA) and stainless-steel tubular reactor. Thermal degradation of corn cob was examined at different heating rates ranging from 2-20°C/min (2, 5, 10 and 20°C/min) in inert atmosphere between 20°C and 900°C. Friedman (FR) and Vyazovkin (VYA) methods were used to determine activation energy values for pyrolysis of hemicellulose, cellulose and lignin. Pyrolysis experiments were carried out in a stainless steel tubular reactor from 200-700°C with a heating rate of 5°C/min, a particle size of 0.2-0.4 mm and nitrogen flow rate of 100 mL/min, which the aim to study how temperature affects bio-oil, bio-char and gas products. Bio-oil and bio-char products were characterized by elemental analysis, FTIR, NMR, XRD and column chromatography. The results of this work showed that three stages have been identified in the thermal decomposition of corn cob biomass. The apparent activation energies obtained for decomposition of hemicellulose, cellulose and lignin original from corn cob were given as 151.45-172.4 KJ/mol, 204-235.87 KJ/mol and 234.45-245.8 KJ/mol, respectively. It was concluded that temperature has a significant effect on product yields. The maximum bio-oil yield of 45.6 wt% was obtained at a pyrolysis temperature of 500°C. Solid and liquid products obtained were characterized by elemental analysis, Fourier transformed infrared spectroscopy (FTIR), nuclear magnetic resonance spectroscopy (NMR), x-ray diffraction (XRD) and column chromatography. The analysis of liquid and solid products showed that bio-oil and bio-char from corn cob biomass could be a prospective source of renewable fuel production and values added chemical products.

Keywords: Hydrological studies, Morphometric parameters, Atlur mandal, SRTM data, ArcGIS
Abstract: This study attempts to study the hydrological characteristics of Atlur area sub-watershed using geoprocessing techniques in GIS. This technique is found relevant for the extraction of study area and its drainage networks. The extracted drainage network was classified according to Strahler’s system of classification, and it reveals that the terrain exhibits dendritic to sub-dendritic drainage patterns. The study area was of fifth order to lower order streams with a drainage density value of 1.48 km/km2. The slope of basin varied from 0-450 and the slope variation is chiefly controlled by the local geology and erosion cycles. The elongation ratio of the basin is 0.63 indicating that the study area is elongated with moderate relief and steep slopes. The drainage texture of the basin is 3.1 indicating an intermediate texture that exists over the region. Remote sensing data (SRTM-DEM) coupled with geoprocessing techniques prove to be a competent tool used in morphometric analysis and evaluation of linear, slope, areal and relief aspects of morphometric parameters. Moreover, the data can be used for basin management and other hydrological studies in future.

Keywords: Bioflocculation, Bioflocculant crude, Wastewater, S. marcesens, Turbidity
Abstract: Two local bacterial isolates were used in the production of bio flocculants that help in reducing some pollutants from wastewater. Pseudomonas aeruginosa and Serratia marcesens were isolated from Rustumiya wastewater treatment plant in Baghdad, Iraq. Kurane method is used in bio flocculate production and Kaolin clay test is applied for flocculation efficiency. The optimum output of bio-flocculant was obtained after an incubation period of 30°C for 48 hr, pH 7 and with an inoculum volume of 2 mL with three concentrations (100, 200 and 300 mg/L). Flocculation efficiency of 86.5%, 87.3% and 94. 5% was seen by S. marcesens, P. aeruginosa and alum, respectively. The maximum activity of reduction process was observed with chemical oxygen demand, biological oxygen demand and turbidity with P. aeruginosa (95%, 64.2%, 68.7%) and S. marcesens (65.2%, 70%, 82.7%), consecutively. P. aeruginosa showed slight but evident reduction efficiency in BOD and COD.

Subject: Exergy, Efficiency and Economic Analysis of Bell Colman Cycle Hybrid Solar Still
Keywords: Desalination, Hybrid still, Exergy efficiency economic analysis, Air refrigeration system
Abstract: The increment of productivity of solar desalination system is obtained by proper modification of solar still. Researchers have done extensive work on solar still by varying the operating and design parameters but productivity is still low. The main objective of this work is to evaluate the modification done on the solar still and compared it with conventional solar still. Exergy, efficiency and economic (3E) analysis was performed for the Bell Colman cycle hybrid solar still. An air refrigeration system was combined with the solar still. Refrigeration system is the best source for both heating and cooling. Experiments were carried out for both conventional and hybrid still with same operating and design parameters. Maximum productivity obtained in hybrid still was 0.863 L/m2/day. The obtained output of 3E analysis for hybrid still depicts that exergy efficiency is maximum as 24% at 15:00 hr, efficiency is maximum as 27% at 16:00 hr and thermo-economic analysis shows that cost of water produced was 0.075$/L/m2. Productivity, exergy, efficiency and cost per liter of hybrid still were compared and found to be more effective than the conventional still.

Subject: Mechanism of Arsenic Release from Minerals and its Mitigation
Keywords: Arsenic, Mobilization, Groundwater, Remediation, Orpiment, Realgar
Abstract: Prevention of leaching of arsenic in groundwater can be effectively done by controlling the discharge from its source minerals. The design of effective methodology for source control requires in-depth knowledge about behaviour of arsenic and its minerals in groundwater and the interactions between other metals under different circumstances. In this study, determination of mechanisms of arsenic leaching, a series of leaching experiments using arsenic sulphide minerals, that is orpiment and realgar was performed at various parameters. Results from the experiment revealed that arsenic leaching increased with leaching time, dissolved oxygen and ferrous concentration and at optimum Fe (II) level, maximum value of arsenic concentration was obtained. The analysis indicates that arsenic is first released from orpiment and realgar as arsenite (III) via the primary reactions. Arsenite (III) is consequently oxidized to arsenate (V), the rate of which increases with dissolved oxygen concentration as more Fe (II) is oxidized to Fe (III). Given this, it is suggested that the oxidative dissolution of iron oxide is the dominant mechanism of arsenic release from minerals into groundwater. Based on the result obtained, a remediate method for effective control of leaching of arsenic from minerals was determined.

Subject: Ecocriticism: Environment and Covid-19
Keywords: Ecocriticism, Covid-19, Pandemic, Environment, Pollution, Crisis, Conservation
Abstract: From air we breathe to water we drink; we are using earth’s resources at an expandable rate and in return, we are producing excess carbon dioxide by cutting trees, urban and rural development and climate change. There are certain questions that are raised and seek to address the relationship between man and nature. The paper will hopefully contribute towards the exposing and undoing of the various kinds of denialism that have held us in its tight hold. Ecocriticism continues to support and facilitate attempts to establish a sense and morally sustainable set of relationships between us, human beings and other inanimate and animate environments. human beings have been continuously destroying their own planet as they may not continue to exist. The paper highlights the Covid-19 crisis and our impact on environment. The present paper gives a summary of coronavirus, its existing state of spread and environmental and ecological risks resulting from the pandemic.
