An impact of sewage pumping failure on coastal water quality of Mumbai, India(Indian Journal of Geo-Marine Sciences)
(Trupti Mardikar, Ritesh Vijay, Indrani Gupta, Rakesh Kumar,46(8),,1528-1538,Year : 2017)
|
A model was conceptualized to emulate the behaviour of coastal water during high and low tides and the impact of the pump failure in present and projected future scenarios was estimated on it. The model was validated before being used for failure scenario simulation. The study indicates that potential adverse effects on water quality are imminent in case of sewage pumping station failure and warrants better planning and management in terms of diversionary and evacuation routes and preparedness plans.

Methyl acrylate modified apple pomace as promising adsorbent for the removal of divalent metal ion from industrial wastewater(Environemental Science and Pollution Research)
(P Chand, M. Bokare, Yogesh B. Pakade,24:,,10454-10465,Year : 2017)
|
Polymerized apple pomace (PoAP) surface was evaluated as adsorbent for the removal of Pb+2, Cd+2, and Ni+2 ions from aqueous solution. PoAP was characterized by FTIR, SEM, EDS, XRD, and BET surface area analyzer. Furthermore, the adsorption influencing parameters such as dose, pH, time, concentration, and temperature were optimized for maximum removal of metal ions from aqueous solution. The maximummonolayer adsorption capacity of PoAP was found to be 106, 34.12, and 19.45 mg, for Pb+2, Cd+2, and Ni+2 ions respectively, using the Langmuir isotherm model. The rate of adsorption was evaluated using pseudo-second order kinetics and intra-particle diffusion. The adsorption data followed pseudo-second order kinetic with the correlation coefficient ( r 2) from 0.99 at al l concentration. Thermodynamic study revealed endothermic nature of Pb+2 and Cd+2 adsorption and exothermic for Ni+2 ions. The rate of adsorption for binary and tertiary mixtures of Pb+2, Ni+2, and Cd+2 metal ion was studied using the ideal adsorbed solution theory. The regeneration study revealed that PoAP could be re-utilized up to 4 cycles for Pb+2 and 2 cycles for Cd+2 and Ni+2 ions. PoAP was successfully applied to real industrial wastewater for the removal of Pb+2, Cd+2, and Ni+2 ions.

Effects of unregulated anthropogenic activities on mixing ratios of volatile organic air pollutants(Air & Waste Management Association)
(Rao P. S, Majumdar, Dipanjali ,65,Issue 9,,Year : 2015)
|
During the months of October to November, many important festivals are celebrated in India. Celebration of these festivals are marked by extensive use of fireworks or pyrotechnics, bonfire, incense burning, open air community cooking, and temporary eateries using crude fuel such as coal, wood, kerosene, cow dung, burning of raw/semiwood, and coconut shells. The present study deals with the influence of these unregulated anthropogenic activities on ambient mixing level of volatile organic compounds (VOCs), especially some carbonyl compounds. The study was undertaken in the metropolitan city of Kolkata, India, with very high population density, which is even higher during festival period. The average total carbonyl level at different sites in Kolkata varied from 134.8 to 516.5 μg m(-3) in pre-festival season, whereas in post-festival season the same varied from 252.2 to 589.3 μg m(-3). Formaldehyde to acetaldehyde ratio altered from 0.62 in pre-festival season to 1.78 in post-festival season. Diurnal variation also altered, indicating variation in source composition of carbonyls. The total ozone forming potential calculated for all 14 carbonyls in pre-festival season increased by 35% in post-festival season. The effect of anthropogenic activities typical to the event of Diwali night characterized by intense execution of pyrotechnics resulted in significantly high level of carbonyl VOCs. Principal component analysis study for the event of Diwali shows clear contribution of the event on certain carbonyl VOCs. The results indicate elevated primary emissions of these pollutants and also their effect on formation of secondary pollutants. The study emphasizes the need of generating awareness among the communities in society as well as need for regulations to minimize the emissions and related hazards to the extent possible

Chemometrics data analysis of marine water quality in Maharashtra, west coast of India(Indian Journal of Geo-Marine Sciences)
(Abhay singh Salunkhe, Nanda Rohra ,Vol 421,,97-105,Year : 2013)
|
Multivariate statistical techniques, including cluster analysis, principal component analysis factor analysis and discriminant analysis, have been used to evaluate spatial variations and to interpret a large and complex water quality data set collected from the Godavari river basin. The data sets, containing 7 parameters, were generated during the 3-years (2007-2009) at 78 different sites along the river and its tributaries. Water quality indices based on four parameters (pH, DO, BOD and FC) calculated for all the sites were found to be medium to good, good to excellent and bad using modified NSF index. Three significant groups (cleaner, slightly and moderately polluted sites) were detected by CA method, and three latent factors were identified by PCA method. The results of DA revealed that only two parameters (i.e. pH and BOD) were necessary for analysis in spatial variation. 83.3% of the original sites were correctly.classified using discriminant function developed from the analysis.

Kinetics, Isotherms and Thermodynamics for the biosorption of Hg(II) onto Carica papaya(Bioremediation Journal)
( Z.V.P. Murthy and B. Jha , 26-34,,,Year : 2011)
|
|
Carica papaya, a novel sorbent, was evaluated for sorption of Hg(II) from synthetic aqueous solutions using various pseudo-second order kinetic models as well as equilibrium sorption models. Batch kinetic and equilibrium experiments were carried out for the sorption of Hg(II) onto C. papaya at pH 6.5 and solid to liquid ratio (s/l) 1.0 g L?1. The kinetic data were fitted to second order models of Sobkowsk and Czerwinski, Ritchie, Blanchard, Ho and McKay, whereas Langmuir, Freundlich, and Redlich-Peterson models were used for the equilibrium data. A comparative study on both linear and nonlinear regression showed that the Sobkowsk and Czerwinski and Ritchie's second order model were the same. Ho and McKay's pseudo-second order model fitted well to the experimental data when compared with the other second order kinetic expressions. Langmuir isotherm parameters obtained from the four Langmuir linear equations by using linear method were dissimilar, but were the same when nonlinear method was used. Additionally, various thermodynamic parameters, such as ?G 0, ?H 0, and ?S 0, were calculated. The negative values of Gibbs free energy (?G 0) and ?H 0 confirmed the intrinsic nature of biosorption process and exothermic, respectively. The negative value of ?S 0 showed the decreased randomness at the solid-solution interface during biosorption.

(Pal P, Chandekar RH
,7(1),,46-49,Year : 2016)
|
This addendum to "Novel application of bacteriophage for controlling foaming in wastewater treatment plant- an eco-friendly approach " includes characteristics of the phages NOC1, NOC2 and NOC3 not discussed in the previous paper. The phage adsorption and host interaction properties, their sensitivity to pH and temperature are inferred. NOC2 is seen to be more temperature resistant while others are not. All the phages show pH sensitivity. There is a variance observed in the behavior of these phages. Also, applicability of the phage based system to large scale reactors is studied and discussed here.

Reduction in the Carbon Footprint of Coal-Fired Thermal Power Plants by Promoting Compact Fluorescent Lamps and Light-Emitting Diodes in Households, Offices, and Commercial Centers(Assessment of Carbon Footprint in Different Industrial Sectors)
(,Vol 2,,105-134 ,Year : 2014)
|
"The electricity consumption of compact fluorescent lamps (CFLs) and light-emitting diode (LED) lamps is low, making them a useful tool for minimizing the rapidly increasing demand for electrical energy in India and elsewhere. This chapter aims to project the likely electrical energy conservation in a scenario of complete replacement of existing fluorescent tubes (FTs) by CFLs or LEDs at the Council of Scientific and Industrial Research (CSIR)-National Environmental Engineering Research Institute (NEERI), including the financial repercussions and indirect reduction in emissions of greenhouse gases (e.g. CO2, N2O, CH4) and carbon footprint, as well as a few important air pollutants (e.g. SO2, NO, black carbon, suspended particulate matter (SPM), mercury) in a coal-fired thermal power plant. The calculations show that the institute could save around 129,870 and 164,970 kW h of electricity per annum by replacing FTs with CFLs and LEDs, respectively, thereby saving approximately INR 1357,142 (US$21,935.37) and INR 1723,937 (US$27,863.85) in electricity costs per year for CFLs and LEDs, respectively. The use of CFLs and LEDs would be able to minimize approximately 47,127.14 and 59,863.94 kg of CO2–C equivalent emissions over a 100-year time horizon, respectively. Moreover, reductions of approximately 961, 1,039, 10, 390, 19, and 0.55 kg of SO2, NO, BC, SPM, PM10 and Hg emissions per year, respectively, could be achieved in electricity conservation by replacing FTs with CFLs at CSIR-NEERI. Reductions of approximately 1,221, 1,320, 13, 495, 25 and 0.7 kg of SO2, NO, BC, SPM, PM10 and Hg emissions per year, respectively, could be achieved by replacing FTs with LEDs at CSIR-NEERI. "

Plant-Mediated Green Synthesis of Iron Nanoparticles(Journal of Nanoparticles)
(,Vol. 2014,,,Year : 2014)
|
In the recent years, nanotechnology has emerged as a state-of-the-art and cutting edge technology with multifarious applications in a wide array of fields. It is a very broad area comprising of nanomaterials, nanotools, and nanodevices. Amongst nanomaterials, majority of the research has mainly focused on nanoparticles as they can be easily prepared and manipulated. Physical and chemical methods are conventionally used for the synthesis of nanoparticles; however, due to several limitations of these methods, research focus has recently shifted towards the development of clean and eco-friendly synthesis protocols. Magnetic nanoparticles constitute an important class of inorganic nanoparticles, which find applications in different areas by virtue of their several unique properties. Nevertheless, in comparison with biological synthesis protocols for noble metal nanoparticles, limited study has been carried out with respect to biological synthesis of magnetic nanoparticles. This review focuses on various studies outlining the novel routes for biosynthesis of these nanoparticles by plant resources along with outlining the future scope of work in this area.

Aerosol Scavenging: Model Application and Sensitivity Analysis in the Indian Context(Environmental Monitoring and Assessment)
(S.Khan, V. Joseph,,,74,Year : 2002)
|
Sulfate aerosols have been found to bethe major contributors to precipitation acidity. Thus,in view of the long-term ecological repercussions theyhave on aquatic ecosystems and their acidity-potential,the present analysis focuses on a case study applicationof the layer-averaged aerosol-scavenging model (Okita et al., 1996) for predicting values of the wet scavengingcoefficient and sulfate concentrations in precipitationsamples on the basis of the information available forsome selected Indian cities. Through sensitivityanalysis (Pandey et al., 1997) the scavengingcoefficient has been found to be very strongly dependenton precipitation intensity. Comparison of modelpredictions has been done with the measured values forDelhi, Mumbai, Calcutta and Chennai in India.
