Keywords: Ultra-low frequency (ULF), Extremely low frequency (ELF), Sprites, Return stroke and lateral corona (RS-LC), Radiation fields
Abstract: Sprites are mesospheric discharges that carry significant exponential electrical currents and produce electromagnetic radiation observed typically in the extremely low frequency (ELF) to ultra-low frequency (ULF) bands. In this paper, it is demonstrated that exponential growth of current in sprite core located at an altitude of 70 km above the surface of he earth is associated with electromagnetic radiation in the frequency range of extremely low frequency .Further, radiation fields due to sprite core are calculated and compared with the radiation fields due to the causative lightning return stroke and lateral corona 9RS-LC) system and it is shown that radiation fields due to sprite core are comparable in magnitude with radiation fields due to causative return stroke and lateral corona system. It is inferred that bright sprite core is the main source of electromagnetic radiation.

Subject: Assessing the need for open Data based Real Time Environment notification system for India
Keywords: Environment, Open data, Real-time notification, Internet of things
Abstract: Real-time notification systems attempt to effectively and efficiently deliver urgent and important information to the end users on their smartphone, personal computers, tabs and other web based electronic devices. The benefits of environment notification systems may range from real-time availability of important information on climate change, expected environmental hazards to heightened awareness on the ways to protect and save the environment. The initiatives for developing an open data based real-time notification system on the environment is relatively less explored in India. This study makes an assessment of the need for such a notification system using the field survey method to have an empirical view from smartphone users. Based on the observation of the respondents, who believe that there is need of such a push notification system, the researchers recommend a blueprint of cloud-based real-time the environment notification system which integrates open data on the environment, like air quality index, water quality index, biodiversity data and the satellite mapped data on the environment. This study, however, was limited to map the need of a notification system for the environment; the investigation may be carried out in other fields as well. There commended blueprint of notification system needs to be tested using suitable simulation protocols.

Keywords: Landfill gas, LandGEM model, Perungudi dump site, Chennai
Abstract: Management of municipal solid waste (MSW) continues to be an important environmental challenge facing by all the urban local bodies. The landfill has been the most common method of managing solid waste. Biodegradation processes within landfill waste release gases (landfill gas) and liquid (leachate) .The landfill gas is a mixture of primarily methane and carbon dioxide with a small proportion of volatile organic compounds. The landfill gas emissions model (Land GEM) version 3.02 developed by USEPA is an automated estimation tool with a Microsoft carbon dioxide, nonmethane organic compounds and individual air pollutants from municipal solid waste landfills. Greater Chennai Corporation is the 4th largest Municipal Corporation in India. The daily solid waste generation is bout 45oo tones. The waste is collected and disposed of in two dump sites at Kodungaiyur and Perungudi. The Perungudi dumpsite is in an area of 200 acres and in use for past 25 years. Landfill gas emission from this site is estimated using the Land GEM model. The model calculates that the CH4 emission from the landfill site as 29780 tonnes/year during 2017.This landfill gas can be captured and utilized as fuel in many ways like to generate electricity, vehicle fuel, sold as a renewable green power.

Abstract: Effective sewage treatment is crucial for healthy living. The paper presents a comparative analysis of efficiencies of sewage treatment plants in Shimla city by monitoring the operational and design parameters for these treatment plants over the summer and winter seasons. It presents a comparative functioning of the plants in respects of eight significant parameters of Ph, Biological Oxygen Demand (BOD), Dissolve Oxygen (DO),alkalinity, acidity, total solids, chlorides and Chemical Oxygen Demand (COD).There are a total of six existing municipal wastewater treatment plant of Shimla city and district, a majority o which function in the process of aerobic conditions with a sole plant operating under anaerobic conditions. Study of various wastewater treatment processes shows that temperature and pH are important factors affecting the efficiency of the treatment system. The performance of the treatment plant working under anaerobic conditions was determined to be poor during the winter conditions because of the dormancy of the bacteria due to low temperature conditions. The biological oxygen demand removal efficiency in aerobic treatment plants were about 90 % in summer and about 80 % in water signifying its process being affected by the surrounding temperature conditions.

Abstract: Air pollution from coal-fired power plants is extensive and varied and contributes to a significant number of adverse environmental and health effects. When coal is burned to produce electricity, the combustion releases a combination of toxic chemicals into the environment and thus the human body. This paper analyzed the ambient air quality, in the vicinity of Sasan Ultra Mega Thermal power plant located in the Sasan village of Madhya Pradesh by measuring the concentration of Sox, NOx and particulate matter using standard methods. For analysis six sampling sites were selected around the thermal power plant under study. The results showed that the concentration of the air pollutants was high in summer due to enhanced dispersion of fugitive dust and other industrial activities similarly in winter season because of lower mixing height and poor distribution lead to high concentration of pollutants. Unlike, post-monsoon had all parameters less than the prescribed limit as per guidelines provided by Central Pollution Control Board (CPCB), New Delhi for National Ambient Air Quality Standard (NAAQS) 2009.The collected data were statistically analyzed with Pearson’s correlation analysis. The effect of environmental pollutants will lead to the adverse impacts on long-term exposure especially on vegetation and human health.

Keywords: Aerobic hybrid bioreactor, Moving bed, Mathematical model, Simplified solution, Euler’s method.
Abstract: A Simplified mathematical model of the moving bed hybrid bioreactor (MBHBR) under steady state has been developed assuming similar reaction kinetics for both suspended and attached growth microorganism and uniform biofilm thickness (Lf).The model considered the sharing between both suspended and attached growth biomass for a single electron donor molecule under moving condition .Monod kinetic expression for substrate utilization into the biofilm coupled with Fick’s second law of molecular diffusion of substrate into the biofilm from the bulk liquid is used to derive the model. Loss of biofilm due to particle-particle collision and hydraulic shear loss contributing to suspended biomass due to particle-particle collision and hydraulic shear loss contributing to suspended biomass are also considered. The velocity of moving particle is derived from the principle of air-water momentum equation. An approximate numerical solution of the model is also proposed using Euler’s method to predict the effluent substrate concentration and the biofilm thickness. Experimental validation is also performed using a laboratory scale, moving bed hybrid bioreactor system treating synthetic chrome bearing carbonaceous wastewater.

Abstract: Soil surface shows conditional variation depending on the soil temperature in terms of emission and absorption of energy in the medium. During this temperature variation, there is an exchange of free radicals, ions, moisture nutrients, nitrogen gas, oxygen and other gaseous parameters as well. Thus, many chemical reactions taking place on the soil surface depends directly (or) indirectly on the soil temperature. In addition, the vegetation of a particular area is mostly concerned about the soil temperature based on seasonal variation and its impact on physical properties, chemical parameters, growth of earthworms and other microorganisms.

Keywords: Physico-chemical parameters, Drinking, Irrigation, BIS, WHO
Abstract: Fifteen groundwater samples (S-1 to S-15) were collected from different sampling sites (handpumps) of Imphal east district of Manipur during monsoon period (June) of 2017.They were analyzed for physic –chemical parameters, such as temperature ,pH, total dissolved solids (TDS), electrical conductivity (EC), total alkalinity (TA) (CO2-3 and HCO3-) , total hardness (TH) , Ca2+ ,Mg2+,Na,K+ and Cl_.Only groundwater represented by S-4 (Heingang Awang Leikai (3) , near foothill), S-13 (Kaina Tourist Home, Kaina) and S-15 physico-chemical parameters are below/within the acceptable limits of BIS standard for drinking water as well as that of WHO. Other remaining groundwater (S-1 to S-3, S-5 to S-12 and S-14) may also be used for drinking purpose in absence of alternate sources. However, some suitable treatments are necessary so as to keep the values of total alkalinity for S-1 to S-3 , S-5 to S-12 and S-14, total hardness for S-1, S-10 and S-12 and concentrations of Mg2+ for S-10 and S-12 below their corresponding acceptable limits of BIS standard drinking water in order to make them perfectly fit for drinking purpose. All the groundwater may also be used for other domestic and irrigation purposes. Based on correlation coefficient data, moderately high values of TDS for groundwater, are attributed to the presence of mainly dissolved bicarbonates of Na+, Ca2+,Mg2+ and K+, and chlorides of Ca+ and Mg2+.Alkalinity for different groundwater, is due to the presence of dissolved NaHCO3, KHCO3, Ca (HC03)2 and Mg (HCO3)2.Further total hardness for different groundwater is due to the presence of mainly bicarbonates and chlorides of Ca2+ and Mg2+ .

Abstract: In this study, the performance of upflow anaerobic sludge blanket (UASB)-clariflocculator integrated system was evaluated while treating low strength wastewater. The COD of the wastewater was removed up to 85 % in the UASB reactor of the integrated system. Water treatment sludge (WTS) was used as a coagulant in a clariflocculator for removing total kjeldahl nitrogen (TKN).The UASB-clariflocculator integrated system removed TKN around 80.32±1.44% at WTS dose of 1000 mg/L.In order to achieve dose of WTS, a dose in the range of 600-1600 mg/L of WTS was varied and found maximum removal of TKN at 1000 mg/L dose of WTS. The results suggested that reuse of water treatment sludge as a coagulant for the post-treatment of UASB reactor effluent would be an attractive option. This technique may save the cost of fresh coagulant chemicals required for the coagulation process.

Abstract: Distillery industries are highly responsible for the tremendous generation of effluent known as distillery spent wash (DSW) .Distillery spent wash is caramelized , recalcitrant toxic pollutant, comprehensive undesirable intense dark brown colour non-consumed liquid accompanied by high COD,BOD, highly acidic pH, containing oraganic and inorganic poisonous ingredient which depends on the raw material furnished.Distillery spent wash also contains sugar decomposition products, such as anthocyanin, tannin and xenobiotic compounds. It causes aquatic and soil pollution due to strong brown colour recalcitrant melanoidin pigment which results in the obstruction of photosynthesis, eutrophication and low pH that acidifies the soil, affecting crop growth. Thus, creating an ecological imbalance and big environmental hassle. Hence, there is the urgent need for removal of colour and pollutants from distillery effluent which has become essential for green chemistry and is approved hygienically. Novel advanced technologies have been used to reduce colour and COD. The current review paper gives an insight of electro coagulation process and advanced oxidation processes, such as ozone, fenton, UV, hybrid treatment to treat spent wash.

Subject: Improving the performance of Water Cooled Chiller using Wastewater from air Handling Unit
Keywords: Water cooled chiller, Air handling unit, Efficiency of chiller
Abstract: Water cooled chillers produce cold water in very huge quantities in industrial space cooling as well as process cooling applications. The water entering the chiller generally will have the atmospheric temperature around 32ºC.The energy consumption can be decreased as less work is involved. The water vapour in the surroundings gets condensed at the air handling unit (AHU) to give 60 kL of water on a daily basis and is rejected to surroundings. By this project, we plan to collect this drain water and it is made used to cool the feed water to the chiller. This method helps to improve the efficiency of the chiller and the overall energy consumption can be reduced. This project mainly aims at the recovery of condensate water which otherwise goes waste. Utilization of low temperature in the condensate to cool the condenser side of the refrigeration unit is made possible through applying the condensate recovery project. Thus this proposed project helps to improve the efficiency of the chiller, improves the effectiveness of the cooling tower and reduction of water consumption.

In DPHP soil moisture and temperature sensor, the temperature sensor is nanoceramic powder based thermistor (27nm) and the heater is made from ITO nanopowder (32nm) .The temperature sensor and the heater are energy efficient, low-cost and accurate that results in efficient , low power and cheap system. The heater and the temperature sensor probes are separated at a distance of 6 mm. The embedded system consists of both hardware and software components. The hardware components are NodeMCU, dual probe heat pulse (DPHP) moisture sensor, thermistor, 3D printed box and stainless steel cylindrical tubes while the software components are Arduino IDE and ThingSpeak.The system monitors the soil parameters through ThingSpeak.com web via a private account at a distance. The system can measure both soil temperature and moisture content upto 3 digit precision.

Abstract: Surface active agents (surfactants) are chemical compounds which are largely used a s raw material in detergent production and their introduction into the environment in large concentrations causes harm to the aquatic bodies and terrestrial environment. Microorganisms were isolated from samples collected from outlets of laundary and dish washing areas. Bacteria were isolated from soil at the outlet of these detergents and blue active substance assay were used to determine the amount of degradation by the bacteria. Pseudomonas sps. Had shown better degradation for cloth washing detergent. Degradation percentage was maximum for sample-4 (Rin) 99.37 % after 48 hr on incubation .Followed by sample -3 (tide) degradation 95.26 %, are showing sample 2 and 1 are showing almost similar degradation percentage ( 84.12 & 8.22 %).
