Subject: Kinetic Modeling of Continuous Stirred Tank Reactor – Operating on Distillery Effluent
Keywords: Anaerobic continuous stirred tank reactor, Distillery effluent, Chemical oxygen demand, Biogas, Pollution, Stover Kincannon kinetic model
Abstract: To identify the viability and performance, distillery effluent having very high organic content was studied on continuous stirred tank reactor (CSTR). Under different organic loading rates (OLR) and optimum conditions for highest chemical oxygen demand (COD) removal and biogas generation was found for OLR of 0.10-0.11 COD kg/day. Highest COD exertion efficiency was found to be around 73% for OLR of 9.166 kg COD/m3/day when hydraulic retention time (HRT) was reduced from 15 to 14 days. Biogas generation was observed to be around 30 L/day with a conversion coefficient of 0.405 and volatile fatty acids (VFA) to alkalinity ratio was recorded to be 0.12 in this stage. Applying the modified Stover Kincannon model to the reactor, the maximum removal rate constant (Umax) and saturation value constant (Kb) were found to be 17.123 kg/m3/day and 33.471 kg/m3/day, respectively. These records are predominantly significant when operating the anaerobic biodigesters for treating the distillery effluent along with the production of biogas as an energy source. CSTR can effectively be employed in treatment of this effluent, however, post bio-digestion effluent still contains considerable COD. To meet the pollution norms and standards it needs to be treated further. To understand the complex biological treatment process of this effluent further trials are required to be conducted.

Abstract: Attention has been given to the concepts of soil quality and soil health as a result of the implementation of sustainable development goals. Soil quality is the capacity of soil to sustain and function effectively as a component of healthy environment. The present study was conducted to assess soil quality with the use of soil microarthropods as indicated by biological quality of soil (QBS-ar) index in two tea agroecosystems with different agronomic practices, namely organic and conventional, located in south Assam.The QBS index is an approach to evaluate soil quality based on the microarthropod fauna present in the edaphic environment. Each type that occurred in the soil samples is given a score ranging from 1-20 called eco-morphological index, based on its adaptation level in the soil environment. The QBS values are slightly higher or similar in the organically managed system as compared to the conventionally managed one. The soil quality of the organic site ranged from medium to very good while that of conventional site was medium only during the sampling periods. The study encourages application of indicator values based on microarthropods to soil quality, management and conservation studies.

Subject: Environmental Impact of Ash Pond of a Thermal Power Plant on Groundwater Quality
Keywords: Ash pond, Leachate, Groundwater contamination, Health impacts, Flyash
Abstract: Ash pond is the term associated with thermal power plants where the ash is disposed of in a low lying area by mixing with water. The water percolates into the subsoil and ash after sun drying will be used for recycling purposes. The physico-chemical properties of groundwater are affected due to wet disposal. The groundwater samples collected from the surrounding villages near an ash pond of a thermal power station (TPS) near Vijayawada were investigated for possible contamination of groundwater. Total dissolved solids, total hardness and sulphates were found to be major quality parameters in the samples. The groundwater quality in majority of sampling locations is not suitable for drinking. Further, leaching studies were performed in laboratory to assess the variation of leaching properties from the ash with respect to time. The leachate was tested for selected physico-chemical parameters and analysed for their variation with time. It is found to have high TDS, turbidity and total hardness and confirmed that leaching is a slow process. A sample survey was conducted in all the villages where water samples were collected. It is noticed that the villagers are facing problems with the ash pond water contamination and dry ash rising into atmosphere. However, the local groundwater is helpful for irrigation purposes due to the low values of sodium absorption ratio and residual sodium carbonate index. The utility of flyash from ash pond was tested for its removal of fluoride. The results of treatability studies indicated that at low concentrations of adsorbent dose, a 70% removal of flouride from synthetic fluoride solution and 50% removal from field sample.

Subject: Solar Disinfection Improves Water Quality to Prevent Diarrhoea in Under-Five Children in Lucknow District, U.P.
Keywords: Solar disinfection intervention, childhood diarrhoea, Water quality
Abstract: Diarrhoea is one of the major causes of death among under-five children (U5C) in India. The consumption of contaminated water, inadequate sanitation and poor hygiene are major risk factors for diarrhoea in developing countries. To determine the effectiveness of solar disinfection intervention (SODIS) in reducing the incidence of diarrhoea among under five children, study was conducted in conveniently selected three urban slums of Lucknow, during the period from 1st May 2019 to 30th April 2020. Ninety-five children from intervention and control areas were included in the study. During follow-up period, occurrence of diarrhoea was monitored and compared between control and intervention area. The reduction in diarrhoea was 64.6%, 75%, 92.8% at the end of first, second and third month, respectively among intervention group when compared to control group. Statistically significant reduction in diarrhoea incidence among SODIS users [IRR= 0.23; 95%CI (0.11, 0.49)] was observed. Significant improvement in bacteriological quality of water was noted after sun exposure (x2=18.337, df=9, p=0.008). In our study, we observed that the diarrhoea prevalence was significantly reduced among intervention group compared to control group. Bacteriological quality of drinking water has been improved after sun exposure. In order to incorporate SODIS practice into daily practice among urban population proper strategy and training is needed.

Subject: Flood Risks, Mangrove Ecosystem and Coastal Megacities: Assessing the Adaptation Benefits of Mangrove Ecosystem to Urban Flood Risk in the H/E Ward of Mumbai
Keywords: Climate change, Ecosystem based adaptation, Mangrove ecosystem, Forest degradation
Abstract: In India, Mumbai city faces the problem of recurrent urban floods. The Mumbai floods of 2005 highlighted the vulnerability of the city to increasing climate change threats. On its face, the causes of the 2005 floods were attributed to heavy rainfall and inadequate drainage system. However, various environmentalists argued that the deterioration of the natural ecosystem,, such as the mangrove’s destruction and Mithi river degradation, were crucial factors in causing the disaster. Also, few empirical studies showed that mangroves could have decreased the impact of 2005 floods by dissipating the incoming wave energy near the coastline. Hence, this paper aims to study mangroves’ role in mitigating the urban flood risk in the H east ward (study area) of Mumbai. The study evaluates the landuse-landcover (LULC) changes in the hydrological processes over time. As the H/E ward lies in the Mithi river catchment area, we processed the digital elevation map (DEM) and used the soil conservation service-curve number (SCS-CN) and kinematic routing method to generate the peak discharge at the river sub- basins in hydrologic engineering centre- hydrologic modelling system (HEC-HMS) software. The river geometry is prepared in hydrologic engineering centre-river analysis system (HEC-RAS) software and flood hazard maps were prepared. We found that there has been an increase of 1.40% in the flood inundation area from 1973 to 2005. The maximum depth at the banks of Vakola Nala (location near mangrove) was 1.77 m in 1973 and it reaches 2.36 m for the landuse in 2005. The results highlight the need to restore mangroves around the coastline to mitigate the risk of urban floods.

Keywords: Flyash, Steel fibers, Hooked end steel fibers, Compressive strength, Steel fiber concrete
Abstract: Development industry is associated either coherently or correspondingly with the cement industry. In concrete, it assumes the part of generally huge, adaptable and energy consuming material. Thus, the replacement of the cement with other cementation material is able to straightforwardly affect the cost of concrete. Therefore, with the secondary cementations material, the flyash has been replaced with cement in different proportions. Replacing cement with flyash will overcome its dumping issues and it will decrease the cost of concrete. It affects strength of the concrete and makes it sustainable. In this investigation, cement has been replaced by flyash mixed with steel fiber reinforced concrete and making specimens to test the compressive, flexural and tensile strength. Steel fibers were added in various percentages, to check the impact of it on the mechanical properties of flyash mixed with steel fiber. The proportion of steel fiber is 0.5%, 1%, 1.5%, 2% and 2.5% and the flyash used to replace cement is 20%, 30%, 40% and 50%. To determine the workability of flyash steel fiber reinforced concrete, slump test was also performed.

Keywords: Sewage, greywater, oil and grease, biosorption, salvinia
Abstract: Inexpensive, rapid and effective removal of oil and grease from biodegradable wastewaters, such as sewage and greywater has been an enduring challenge. In an attempt to find absorbents that can accomplish this task, we have explored two aquatic weeds Salvinia (Salvinia molesta) and water hyacinth (Eichhornia crassipes), three terrestrial plants purple milkweed (Asclepiaspur purascens), cogon grass (Imperatacy lindrica), kenaf (Hibiscus cannabinus) and four forms of organic waste that are known to be very hard to biodegrade – banana trunk fibre, rice husk, coir pith and discarded jute bags. It is seen that Salvinia is the most efficient remover of oil and grease, followed by water hyacinth and kenaf. Considering that both Salvinia and water hyacinth are not only abundantly available, but their removal is in the interest of protecting the wetlands, the present work opens a possibility of utilization of the weeds to the benefit of the environment. Efforts were also made to identify the fungal species present in the greywater and to see whether their cultures could degrade oil or ghee. But the attempts did not lead to any utilizable process and the use of the biosorbents reported in this study appears to be the preferred option for the removal of oil and grease.

Abstract: Morphometric analysis describes the nature of the land formation on the earth’s surface in the form of linear, aerial, and relief aspects. The morphometric analysis also helps in any hydrological investigation, like groundwater potential, quality and basin assessment and management. The present study carried out linear and aerial aspects of upstream Thandava reservoir located in Visakhapatnam district, Andhra Pradesh state, India. Alongwith field visit, remote sensing techniques and GIS software (Arc GIS 10.3) have been used in this study for the extraction of accurate data and analysis. Satellite images and Shuttle Radar Topographic Mission (SRTM) data had downloaded from USGS (earthexplorer.usgs.gov) have been taken as inputs for the performance of GIS outcomes. GIS has classified the study area into four sub-basins and the morphometric parameters have been computed using standard formulae. The micro-watersheds in an area less than 5 km2 have not been taken into account for analysis and based on the correlation of parameters of the basins the character of basins have shown in this study. Finally, by giving prioritization to the sub-basins, we could take sustainable measures for soil–water conservation, erosion control activities and flood risk mitigation at the right locations in the study area for improved planning and management.

Keywords: Adsorption, Biopolymer, Coconut cake, Dye removal, pH
Abstract: Adsorption is a universal water treatment process since it can be applied to remove soluble and insoluble organic, inorganic and biological materials. Biopolymers having rigid structural features and required surface properties are being used as adsorbents to remove pollutants from aqueous systems due to their availability, efficiency and environmental friendliness. The present research work is a study of the adsorption capability of treated coconut cake to remove certain dyes from water at different hydrogen ion concentrations (pH). The monomeric materials from crude coconut cake are removed by proper treatments and the remaining polymeric mixture has properties to function as adsorbents in water purification processes. The treated coconut cake is mainly a mixture of cellulose and proteins and their functional group diversity can be exploited. The pH-dependence of adsorption of dyes is explained in terms of the surface modifications that have occurred to the biopolymeric mixture with respect to the pH of the medium.

Abstract: Green spaces, such as parks; urban forests; vacant plot, gardens and yards, campus areas, landfills and blue spaces, including streams, lakes, ponds, artificial swales and storm water retention ponds are the diverse of habitats of urban ecosystem. To offer a safe shelter in the urban environment; wetlands, ponds, swales and trenches for water storage can promote the biodiversity of aquatic organisms. Ponds of a geographical area always play an significant role to preserve the potentiality of groundwater, maintenance of aesthetic beauty with their untouched view for their locality, etc. Anthropogenic pollutants (sewage flow, solid waste, road salt and heavy metals, etc.), invasive species and active mismanagement—particularly the removal of riparian vegetation are the major anthropogenic stressors with results of the worsen condition of aquatic urban biodiversity. The heavy load of sewage water and solid waste in absence of sewerage connection or negligence of waste collection in the city are poorly reducing the area of water bodies, for example ponds, lakes, etc. Being a developing country, India, have prosperous freshwater resources in the form of rivers, kunds, ponds and lakes, etc. District Jaunpur of Uttar Pradesh is popularly known for its ponds. The city, situated on the bank of river Gomti which bisects the city of Jaunpur (located between 25°44’ to 25°46’ north latitude and 82°40’ to 82°43’ east longitude) in the north and south directions. The developments, urbanization and load of the various pollutant sources lead to deterioration of the ponds. Population growth and urbanisation rate in the city is very high during last few decades. There are about nine to ten ponds are located within the city. This study aims to investigate the level of physico-chemical properties, spatio-temporal distribution and also wish to find out the major component (using PCA) among all the parameters of major urban ponds in the ecological system of Jaunpur city which is located within the municipal area of the city.

Subject: Bioremoval of Carpet Dye from Effluent and Their Influence on the Growth of Tomato (Gaytri F1) and Cicer arietinum
Keywords: Textile water, Wastewater, Removal, Aspergillus niger MTC1344, Bioremoval, Germination
Abstract: The textile industry is one of the largest consumers of potable water and consequently, produces a huge amount of dye-containing wastewater. Discharge of this dye-bearing wastewater into the rivers poses severe problems to the aquatic life, food web and causes damage to the aesthetic nature of the environment. Colour removal from this wastewater is necessary not only because of its potential toxicity, but also mainly due to its visibility problem. There have been various techniques for the removal of dyes, like physical, chemical and biological, but the effectiveness of bioremoval of dye from wastewater has made it an ideal alternative to other treatment methods. The objective of this paper is to study the potential of removal of dye from textile water by fungi Aspergillus niger MTC1344 and its subsequent impact on the growth of the tomato and gram. Aspergillus niger is shown to be an efficient fungus for removal of Carpet dye effluent and it can decolourize dye effluent upto 78.40±0.305 on 7th day of the incubation period. Germination, seedling growth and shoot length showed a significant increase at 10% and 25% of the effluent concentration.

Subject: A Household Survey During Corona Virus Pandemic to Assess Indoor Air Quality and their Correlation with Women’s Health Parameters
Keywords: Household air pollution, Biomass fuel, Chulha, Cardiovascular diseases, Respiratory issues, Particulate matter
Abstract: Releases from biomass burning are a key basis of household air pollution (HAP) and this is estimated to originate millions of early fatalities globally. HAP is closely allied with respiratory sickness. Main objective of the survey is to assess indoor air quality (IAQ) during lockdown amid COVID-19 and to confirm the lockdown consequences and alliance between some risk and respiratory issues among rural women of the Chambal region in Madhya Pradesh. The questionnaire-based survey was conducted during lockdown, that is from April 2020 to May 2020. Study was confined to four villages (Adupurajagir, Chourai, Mitawali-Padhawali and Gora) of districts from Chambal zone, namely Gwalior, Bhind, Morena and Datia, respectively. On the basis of various criteria, such as demographic characteristics, household characteristics, kitchen characteristics, cooking stove (chulha) characteristics, cooking pattern, use of different types of biomass fuel, ventilation pattern, health history of cook and their household members. Finally, 152 households were surveyed and 100 samples were eligible hence, 25 households from each village were selected for this study.

Subject: Optimizing Odds of Energy Supply by Reducing Corresponding Environmental Impacts
Keywords: Energy supply system, Environmental impact, Technology assessment, Environmental footprint, Sustainable development
Abstract: The innovative thinking way of human beings has always supported desired increase in human’s quality of life. Nevertheless emerging industrial activities have had positive desired impacts on human’s quality of life and also negative undesired ones, especially on environment and society. Undesired impacts of conventional energy technologies have especially been perceivable on environment. In this regard chances and challenges of energy technologies during their whole life cycle should be considered, starting with corresponding energy supply systems. These systems, which are widely based on fossil fuels, since a while starting to use also renewable energy resources, have to be carefully analysed and assessed by considering assure sustainability of human society. In this regard not only technological and economic criteria have to be taken into account but also environmental and social ones. By using methods and instruments of technology assessment, environmental impacts of energy supply systems can be holistically analyzed and assessed. In this regard corresponding environmental footprint will be established for energy supply systems in the context of a Romanian case study and compared to Indian situation in this field. Optimizing odds of energy supply systems can be in this way recognized in order to minimize environmental impacts.
