Prioritization of catchments based on soil erosion using remote sensing and GIS
(Gajanan K. Khadse, Ritesh Vijay P. K. Labhasetwar ,,,,Year : 2015)
|
Water and soil are the most essential natural resources for socioeconomic development and sustenance of life. A study of soil and water dynamics at a watershed level facilitates a scientific approach towards their conservation and management. Remote sensing and Geographic Information System are tools that help to plan and manage natural resources on watershed basis. Studies were conducted for the formulation of catchment area treatment plan based on watershed prioritization with soil erosion studies using remote sensing techniques, corroborated with Geographic Information System (GIS), secondary data and ground truth information. Estimation of runoff and sediment yield is necessary in prioritization of catchment for the design of soil conservation structures and for identifying the critical erosion-prone areas of a catchment for implementation of best management plan with limited resources. The Universal Soil Loss Equation, Sediment Yield Determination and silt yield index methods are used for runoff and soil loss estimation for prioritization of the catchments. On the basis of soil erosion classes, the watersheds were grouped into very high, high, moderate and low priorities. High-priority watersheds need immediate attention for soil and water conservation, whereas low-priority watershed having good vegetative cover and low silt yield index may not need immediate attention for such treatments.

Fly ash based geopolymer concrete a new technology towards the greener environment- A Review(International Journal of Innovative Research in Science, Engineering and Technology)
(Abhishek Bisarya, R.K.Chouhan, Manish Mudgal and S.S.Amritphale,4,12,,Year : 2015)

Concrete usage around the world is second only after water. Ordinary Portland Cement (OPC) is conventionally used as the primary binder to produce concrete. The environmental issues associated with the production of OPC are well known. The amount of CO2 released during the manufacture of OPC due to calcinations of lime stone and combustion of fossil fuel is in order of about one ton for every ton of OPC produced. In addition the extent of energy required to produce OPC is only next to seel and aluminum. Therefore there is urgent need to reduce the CO2 emission. Geopolymer concrete (GPC) is the material for the future, since it is environmental friendly material as during its production about 80% CO2 is less emitted as compared to OPC. Geopolymer is a novel binding material produced by polymeric reaction of alkaline liquid with silicon and aluminum rich materials like fly ash, rice husk, blast furnace slag, silica fumes etc. It has been found that higher compressive strength is easily achievable in a short period to time in GPC as compared to OPC and has an excellent resistance to acid and sulphate attack when compared to OPC. It can be said that production of geopolymer concrete has a relative higher strength excellent volume stability and better durability. Thus geopolymer concrete may be the future alternate material to the ordinary portland cement concrete.

Nanocrystalline cellulose for removal of tetracycline hydrochloride from water via biosorption: Equilibrium, kinetic and thermodynamic studies(Ecological Engineering)
(M.Rathod, S. Halder and ShaikBasha,84,,240-249,Year : 2015)
|
Crystalline nanocellulose, synthesized from green seaweed, Ulva lactuca, was investigated for the sorption of tetracycline hydrochloride (TC) from aqueous solutions. The effects of pH, contact time, concentration of TC and desorption were studied in batch mode. The kinetics of TC biosorption was very fast and reached equilibrium in almost 2 h. The kinetic data was well described by double exponential and the pseudo-second-order kinetic models. Film diffusion is the rate-limiting step for the biosorption of TC on to crystalline nanocellulose. Both Redlich–Peterson (R–P) and Polanyi–Manes (P–M) isotherm models described the equilibrium data well. The values of maximum sorption capacities (6.48–7.73 mg/g for R–P and 6.57–7.96 mg/g for P–M models) increased with temperature. A thermodynamic study (?H° = 22.64 kJ/mol, ?S° = 9.85 kJ/(mol/K)) demonstrated that biosorption of TC is spontaneous, endothermic and an entropy-driven process. The reusability of sorbent was achieved by HNO3 (5 w/w%) with desorption efficiency of 95.20% in 4 h. The overall results have significant implications for the removal of TC from aqueous solution with crystalline nanocellulose.

Hydrodynamic and Advection-Dispersion Simulation of Cool Seawater Discharges from an LNG Facility(Indian Journal of Geo-Marine Sciences)
(Ankit Gupta, Ritesh Vijay, Rakesh Kumar,49,,7-14,Year : 2015)
|
The impact of cool seawater discharge in the coastal waters from a Liquefied Natural Gas (LNG) plant has been simulated using MIKE21. In this work, hydrodynamics conditions of the coastal waters were calibrated and corroborated to predict the cool seawater discharge under two plant design scenarios by selecting flow rate 15 m3 /s and 10 m3 /s with a temperature drop of 5 °C and 7 °C, respectively. The simulations were carried out under different scenarios, to arrive at the best possible case to minimize the potential impact on the coastal environment. Both the simulated scenarios complied with the available World Bank guidelines for LNG facilities. However, the designed scenario of flow rate 10 m3 /s with a temperature drop of 7 °C between inlet and outlet presents a better choice as it reduces the pumping power of seawater intake. As there are no Indian guidelines for cool seawater discharges from LNG plant, the present work can support the policymakers and regulators to formulate coherent discharge standards.

Distillery effluent as a liquid fertilizer: a win-win option for sustainable agriculture(Environmental Technology)
(Kumari, K., Ranjan, N., Kumar, S.,& Sinha, R.C.
,37, ,,381-387,Year : 2015)
|
"A promising approach to recycle the residual distillery waste as a potential liquid fertilizer has been discussed in this paper. Field studies were conducted on Brassica compestris to assess the potential of the diluted post- methanated distillery effluent. The results indicated that there was not much variation in pH, conductivity and nitrate of soil, whereas total dissolved solids, conductivity, nitrate and chemical oxygen demand of the well water increased slightly but well within the permissible limit. However, there was a significant increase in the plant biomass, diameter of the shoot and root, area of leaf, as well as number and length of pods and root hairs. The hydrophilic colloids of the seed increased significantly (p < .01) and the yield of mustard seeds was increased by 30% as compared to the conventional fertilizer. The carbohydrate, chlorophyll and ascorbic acid content of the leaf, stem and root were also analysed and its morpho- physiological significance is also presented in this paper."

GIS based DRASTIC approach for groundwater vulnerability in Puri city, India(Journal of Environmental Science and Engineering)
(Ritesh Vijay, S. S. Ramya and P. K. Mohapatra Journal ,,,,Year : 2015)
|
Groundwater pollution is mainly caused due to the domestic and industrial activities which pollute the shallow aquifers. Puri city is such an important and pilgrim place where groundwater is getting contaminated by various anthropogenic activities. The vulnerability assessment of groundwater is mainly carried out to define the areas critical for the groundwater contamination. For this, GIS based DRASTIC model was used to assess the groundwater vulnerability considering groundwater level, hydro-geological parameters, land use pattern and topographic condition. It was found that most of the city area is highly vulnerable to groundwater contamination due to sandy aquifer property. The output of DRASTIC model helps in suggesting measures for protecting the groundwater from further contamination and management.

Tidal and seasonal variations in water quality of Thane creek, Mumbai, India: a statistical analysis(Indian Journal of Geo-Marine Sciences)
(Ritesh Vijay, Puja Khobragade, S. S. Dhage, Ankit Gupta and S. R. Wate,44,6,,Year : 2015)
|
Water quality of Thane creek was assessed spatially and temporally based on receiving waterbody standards and nutrient parameters. Due to large data set and variation in water quality, statistical analysis was carried out to summarize a data set quantitatively using Box and Whiskers plots. These plots helped to display data spread at a glance, reveal data symmetry and skewness as well as the presence of outliers. Further, Spearman’s correlation matrices were generated to establish the relationship between physico-chemical and bacteriological parameters and found to have significant correlation between them. The study reveals that the Thane creek is polluted based on receiving waterbody standards in all the seasons even during low and high tides. The creek water is more polluted in the upper stretch as compared to middle and lower stretches. Immediate attention is required for the

UV induced photocatalytic degradation of aqueous acetaminophen: the role of adsorption and reaction kinetics(Environmental Science and Pollution Research)
( David Keane, Kieran Nolan, Michael Oelgemoller, Jenny Lawler, John M. Tobin, Anne Morrissey,22,,2219-2230,Year : 2015)
|
Nanostructured titania supported on activated carbon (AC), termed as integrated photocatalytic adsorbents (IPCAs), were prepared by ultrasonication and investigated for the photocatalytic degradation of acetaminophen (AMP), a common analgesic and antipyretic drug. The IPCAs showed high affinity towards AMP (in dark adsorption studies), with the amount adsorbed proportional to the TiO2 content; the highest adsorption was at 10 wt% TiO2. Equilibrium isotherm studies showed that the adsorption followed the Langmuir model, indicating the dependence of the reaction on an initial adsorption step, with maximum adsorption capacity of 28.4 mg/g for 10 % TiO2 IPCA. The effects of initial pH, catalyst amount and initial AMP concentration on the photocatalytic degradation rates were studied. Generally, the AMP photodegradation activity of the IPCAs was better than that of bare TiO2. Kinetic studies on the photocatalytic degradation of AMP under UV suggest that the degradation followed Langmuir–Hinshelwood (L–H) kinetics, with an adsorption rate constant (K) that was considerably higher than the photocatalytic rate constant (k r), indicating that the photocatalysis of AMP is the rate-determining step during the adsorption/photocatalysis process.
