Noise Pollution is becoming one of the most challenging problems in a developing city like Vijayawada in Andhra Pradesh. Due to the proximity to the capital city of the Andhra Pradesh, Amaravati, vehicular flow in Vijayawada has increased manifold. The people commuting to and from Vijayawada to the nearby areas for their livelihood also increased c...

Noise is unwanted sound and Noise due to traffic is increasing due to increasing vehicular movement on the roads. The increased noise levels lead to several adverse impacts on health. Vijayawada the second most important city in the State of Andhra Pradesh, India is considered as a commercial capital of the State and is very close to the existing c...

Human health depends mainly on purity of air we breathe. The ambient air is getting polluted due to increased vehicular movement and day-to-day needs. This causes adverse impacts on human health ranging from respiratory problems, bronchitis, asthma and cardio vascular problems. A system should be required that will indicate the severity of air poll...

Study of Hydrological parameters in Andhra Pradesh State in India. Study of Infiltration trends, Rainfall trends and modeling the infiltration rates and its coorelation with soil type and rainfall pattern are discussed.

Noise Pollution in Vijayawada

The ash and sulphur contents of the solid fuels lead to increased air pollution levels in the surroundings due to their burning. While unorganized burning such as municipal solid waste burning for reduction in volume leads to area emissions, the organized burning of coal in all the industries for their operational purposes leads to area and point s...

Proper quantification and characterization are essential for successful solid waste management. Proper segregation, collection, recovery and systematic disposal are very rarely followed in India, particularly in rural areas. Solid waste management in Mylavaram, a Panchayat in Krishna district, AP is considered in the present study and examined the...

Noise pollution is caused due to day-today activities and transportation activities. It is creating severe impacts on human beings ranging from annoyance, sleeplessness to decreased performance and increased blood pressure. Noise pollution due to transportation related activities is of major concern as vehicular movement is increasing due to the in...

The ground water quality is studied in the villages of AP Capital Region Development Area, Andhra Pradesh, India, which is necessitated in view of urgency in overall improvement of the region due to bifurcation of the State. Twenty ground water samples from ten locations within the geographical area of the region are collected and analyzed for thei...

Artificial Neural Networks are applied to the literature data pertaining to adsorption batch studies to develop and validate a model that can predict the Pollutant Removal Efficiency (PRE). Back-Propagation Network (BPN) is used with one hidden layer. The BPN model is systematically trained with 440 data points and is validated with 73 data points...

Two codes of Bureau of Indian Standards, viz., IS 2752:1995 and IS 8366:1989 are available for classification of adsorbents for their use in specific purposes based on their physico-chemical characteristics. No IS code is available for directly assessing the suitability of activated carbon for contaminated water treatment. Two specific categories o...

The adsorption system is analytically modeled and simulated using the Homogeneous Surface Diffusion Model (HSDM) for batch studies of adsorption. The HSDM is discretized and solved using pure implicit scheme of finite difference method and Simpson's 1/3rd rule. The model is tested using two sets of literature data viz., Data-1 and Data-2. The model...

With the Basel ban, imposing restrictions on Trans-boundary movement of hazardous wastes, coming into force with effect from 1.1.1998, the concept of treatment and safe disposal of hazardous wastes (HWs) assumes paramount significance. The annual HW generation in India is estimated at 0.3-0.5 million tonnes. As per the ideal industrial siting crite...

SYNOPSIS This paper deals with modeling the suitability of novel adsorbents in terms of the isotherm constants and temperature. Two different models viz., Linear Regression Model (LRM) and Model based on Normalized Sum of Squares (NMSS) are used. A database comprising of 120 data points (DB-1) pertaining to Freundlich constants is compiled from lit...

Majority of the manufacturing activities in an industry, at times, are also associated with generation of pollution. It is often looked at the Industrial sector being not paying much adherence to their commitments promised before receiving permission for their establishment and operation from concerned authorities of different organizations such as...

Energy recovery from Municipal Solid Wastes (MSW) generated in New Delhi is studied. The two options available viz., recovery of Biogas and energy due to the firing of MSW as fuel are reviewed. Continuous recovery of energy from the city's MSW through Biogas needs a lot of planning with respect to the design, construction, operation and maintenance...

The reliability of Physical Modeling in applications such as Adsorption and Heat transfer studies is not accurate since their mechanisms are complex and a proper understanding of the physics of the system is incomplete. In order to verify the applicability of Regression technique for Physical Modeling, a physical model is developed based on Multipl...

Site selection and ranking of a suitable site for a Treatment, Storage and Disposal Facility (TSDF) ear marked for hazardous wastes is an important aspect since it covers several attributes covering site based information, physico-chemical characteristics of the hazardous wastes, and available technology for hazardous waste treatment. Guidelines ar...

The global problem of fresh water depletion is addressed. The seriousness and the need to have concern about this crisis are emphasized. The causes for this crisis and some suggestions in handling this alarming situation at the local level with reference to Indian conditions are discussed in detail.

Life Cycle Inventory Analysis (LCIA) is a part of the Life Cycle Assessment (LCA) and is a thorough procedure accounting for the environmental loads during the product's life cycle. LCA is an approach to analyze the environmental implications of product and service systems. An indigenous adsorbent is prepared in the laboratory from sawdust using ch...

The population growth is increasing the demand and hence putting pressure on Natural Resources to cater to the needs of various requirements of the population in their day-to-day life. The Natural Resources are converted into an effective product/service through an appropriate Technology. Excess waste is generated in the process due to ineffective...

A number of novel adsorbents are being investigated in search of an alternative to Commercial Activated Carbon (CAC). Several methodologies are being followed in the preparation of adsorbents from their raw materials. The raw materials used for the preparation of novel adsorbents are broadly classified under three main categories: (i) Agricultural...

It is found from literature that the activated carbon prepared from various raw materials are being examined and reported for more characteristics than prescribed under the relevant IS codes. However, some of the characteristics prescribed by the IS codes are not being examined by the earlier investigators. A database comprising the physico-chemica...
