(Ritesh Vijay, Puja Khobragade, R. A. Sohony, Rakesh Kumar and S. R. Wate ,43,,10,Year : 2014)
|
To assess the impact of sewage discharges on creek water quality, a hydrodynamic and water quality simulation was carried out for Thane Creek. DO and BOD values showed non-compliance up to middle and upper stretches during low tide and even in upper stretch during high tide. FC was found beyond compliance level during low and high tides. Simulated results were correlated with observed tide and current as hydrodynamics and DO, BOD and FC as water quality parameters with correlation coefficients 0.66 to 0.91.

Accurate representation of dispersion of air pollutants is essential for environmental management and planning purposes. In the present study, an attempt has been made to investigate the improvement of pollution dispersion using AERMOD model which includes atmospheric boundary layer processes explicitly. Ranchi region, a fast growing urban city with industries and vehicular pollution in the Jharkhand state of India is chosen. Surface micro-meteorological tower data and upper air radiosonde observations are utilized in the study. Surface boundary layer parameters such as friction velocity and sensible heat flux used as input to AERMOD model are obtained from flux-profile relationships and validated with turbulence measurements. The pollutant concentrations includes industrial as well as vehicular sources predicted by AERMOD are validated with the ambient air quality data of Central Pollution Control Board at Ranchi. Results reveal that AERMOD performed well in representing air pollution dispersion over Ranchi region.

Assessment of traffic noise on highway passing from urban agglomeration(Fluctuation and Noise Letters )
(Ritesh Vijay, Chandan Kori, Manoj Kumar, T. Chakrabarti Rajesh Gupta,13,4,1450031,Year : 2014)
|
Assessment of traffic noise pollution in developing countries is complex due to heterogeneity in traffic conditions like traffic volume, road width, honking, etc. To analyze the impact of such variables, a research study was carried out on a national highway passing from an urban agglomeration. Traffic volume and noise levels (L10, Lmin, Lmax, Leq and L90) were measured during morning and evening peak hours. Contribution of noise by individual vehicle was estimated using passenger car noise unit. Extent of noise pollution and impact of noisy vehicles were estimated using noise pollution level and traffic noise index, respectively. Noise levels were observed to be above the prescribed Indian and International standards. As per audio spectrum analysis of traffic noise, honking contributed an additional 3–4 dB(A) noise. Based on data analysis, a positive relationship was observed between noise levels and honking while negative correlation was observed between noise levels and road width. The study suggests that proper monitoring and analysis of traffic data is required for better planning of noise abatement measures.

Identification of inlet and outlet locations for cool seawater discharges from an LNG facility(International Journal of Environmental Research)
(Ankit Gupta, Ritesh Vijay, Vikash k Kushwaha, S. R. Wate,8,4,953-960,Year : 2014)
|
Two-dimensional hydrodynamic and advection-dispersion simulations were carried out to identify the appropriate locations of inlet and outlet for cool seawater discharges from the proposed Liquefied Natural Gas (LNG) terminal using MIKE-21 suites of software. The model simulations were validated by comparing the observed and simulated hydrodynamics in terms of water depths, current speeds and directions. The model is satisfactorily correlated with coefficients 0.98, 0.86 and 0.91 for water depth, current speed and direction, respectively. The validated model was extended to predict the advection-dispersion phenomena for the two scenarios based on positions of inlet and outlet and their discharges. The predicted results of cool water discharges were compared to the existing Environmental Health and Safety, World Bank guidelines for LNG discharge facilities. It was observed that a trade-off is required before taking engineering decisions for selecting an environmentally acceptable and energy efficient option for such cool water discharges from an LNG facility.

Optimization of solid waste collection routes using Premium Solver Platform(International Journal of Environment and Waste Management)
(A. S. Aremu Ritesh Vijay Murtadha Adekilekun Tijani,14,3,222-231 ,Year : 2014)
|
Improvement of collection operation by route optimization is complex and time consuming. This study illustrates the application of an efficient and high speed optimization software; Premium Solver Platform V.12 to optimize tours for the collection of municipal solid waste in Ilorin, Nigeria. Data required for optimization was obtained from the municipal solid waste management authority, field studies and digitized map of Ilorin. Thereafter the optimization problem was then formulated as a travelling salesman problem (TSP) on a Microsoft Excel spreadsheet. The solver engine of the software generated optimal result for the TSP in less than 1 second for each computer run and the overall output showed reduction in the tour distance by 0.27 to 32.16 %. This reduction could in turn decrease time, costs and emissions associated with collection operation. The method proposed in this study can also generate accurate decisions within a short period for large routing problems especially in mega cities.

Start-up and Performance of a Hybrid Anoxic Reactor for Biological Denitrification(Bioresource Technology)
(Bhuvanesh, S., Maneesh, N., Sreekrishnan, T.R.,129,,78-84,Year : 2014)
|
This study was aimed at denitrification of wastewater using a hybrid anoxic reactor (HAR), which uses self immobilized microbial granules under fluidized condition. Granulation of the denitrifying biomass was studied in the HAR with methanol and acetate as carbon sources. It was observed that by the end of 15 day almost spherical granules with a settling velocity of 1.5 cm/s and a mean diameter of 0.5 mm were produced. By stepwise increment of the influent nitrate concentration, the removal rate reached 740 g NO3–N/m3 day with a removal efficiency of almost 100% at a hydraulic retention time of 6 h or higher. For complete denitrification, the ratio of the organic substrate required to amount of nitrate nitrogen removed was as low as 2.2 g

Adoptive Neuro-Fuzzy Inference System for Traffic Noise Prediction(International Journal of Computer Applications)
(A Sharma, R Vijay, GL Bodhe, LG Mailk,98 (13),,, 14-19,Year : 2014)
|
|
An adaptive neuro-fuzzy inference system (ANFIS) is implemented to evaluate traffic noise under heterogeneous traffic conditions of Nagpur city, India. The major factors which affect the traffic noise are traffic flow, vehicle speed and honking. These factors are considered as input parameters to ANFIS model for traffic noise estimation. The proposed ANFIS model has implemented for traffic noise estimation at eight locations. The results have been compared and analyzed with observed noise levels and the coefficient of co-relation between observed and predicted noise level was found to be in range of 0.70 to 0.95. The model performance has also been compared with Federal Highway Administration (FHWA), Calculation of road traffic noise (CRTN) and regression noise models and it is observed that the model performs better than conventional statistical noise model.

Development of a traffic noise prediction model for an urban environment(Noise and Health )
(A Sharma, GL Bodhe, G Schimak,16 (68), ,,63,Year : 2014)
|
"The objective of this study is to develop a traffic noise model under diverse traffic conditions in metropolitan cities. The model has been developed to calculate equivalent traffic noise based on four input variables i.e. equivalent traffic flow (Q e ), equivalent vehicle speed (S e ) and distance (d) and honking (h). The traffic data is collected and statistically analyzed in three different cases for 15-min during morning and evening rush hours. Case I represents congested traffic where equivalent vehicle speed is <30 km/h while case II represents free-flowing traffic where equivalent vehicle speed is >30 km/h and case III represents calm traffic where no honking is recorded. The noise model showed better results than earlier developed noise model for Indian traffic conditions. A comparative assessment between present and earlier developed noise model has also been presented in the study. The model is validated with measured noise levels and the correlation coefficients between measured and predicted noise levels were found to be 0.75, 0.83 and 0.86 for case I, II and III respectively. The noise model performs reasonably well under different traffic conditions and could be implemented for traffic noise prediction at other region as well.
