The world of Environmental Engineering is moving from one crisis to another. Energy sustainability stands today as a severe and vehement problem of our present-day civilization. Man's civilization is in danger of the future environmental crisis which looms large at the distant horizon of destiny. Provision of drinking water remain as the most difficult problem of Environmental Engineering in our human civilization today. With such an environmental crisis and environmental disaster, the question of novel separation processes such as membrane separation processes stand today as effective procedures in tackling the vicious problem of provision of clean and pure drinking water. The vision for the future is immense, wide and bright. Success and diligence today remain as the key issues of the sound technical know-how of novel separation processes and membrane separation processes. Water crisis is a primordial issue and of serious concern in our present generation and our present day civilization. Issues which are mind-boggling and crucial are groundwater pollution and groundwater remediation. The situation is extremely grave in developing countries throughout the world. Now, in such a critical as well as vexing juncture, the world of challenges needs reassessment and rethinking. Membrane science and membrane separation processes will surely stand towards the imminent crisis of our civilization. Reverse osmosis and nanofiltration stand as future dimensions of scientific research in the future path of innovation and intuition. The presented treatise delineates the immense importance of reverse osmosis and nanofiltration and its impact on global water shortage and the visionary aspects of environmental sustainability.
Corrosion in underground storage tanks has become an important issue which needs to be figured out before any economical loss occurs. The basic aim of the present work is to study the average life of underground storage tanks using suitable numerical model. Mean Time to Corrosion Failure (MTCF) model is the proven model for predicting the average life of the underground storage tanks based on soil and tank characteristics. In this present paper, the average life of underground storage tanks using MTCF model based on the available experimental data of corrosion rate, resistivity and other characteristics of tank and soil has been determined. The estimated maximum MTCF is 27.3 years and minimum is 17.4 years. Hence, in worst condition, the life of considered tank would be around 17.4 years and in best condition, it would be upto 27.3 years. The predicted results are in well agreement with the literature data as the tank failure from external corrosion ranged from 5 to 35 years. The MTCF can be used as the best suitable model to determine the average life of the underground storage tanks.
This paper discusses the feasibility of using activated coir pith as adsorbent prepared from coconut husk for removal of Malachite Green. Batch adsorption experiments are performed by considering contact time, pH, speed of agitation and particle size as variables. The data on equilibrium is fitted to Freundlich, Langmuir, Sips and Tempkin isotherms. The xperimental data is found to be in close agreement with Tempkin adsorption isotherm (R2 value=0.93) followed by Sips and Freundlich (R2 value=0.913). Some experiments on % removal of Methylene blue using the same adsorbent suggested Malachite Green to be adsorbed better than Methylene blue.
Consequent to rising oil prices and growing fears of climate change, biofuels are receiving increasing consideration worldwide as alternative to fossil fuels. Biofuels are being considered as sustainable alternatives to fossil fuels, because of their potential to promote energy security and reduce greenhouse gas emissions. At the same time, biofuels also provide opportunities for job creation and diversification of rural economy. Hitherto the large-scale production of biofuels requires shift from our current dependence on fossil fuels and brings with it a suite of potential problems. Second generation biofuels derived from ligno-cellulosic agricultural residue are increasingly attractive to the biofuel industry because they are expected to be more efficient than first generation crops and they will not compete directly with food production.
The aim of this review is to provide an overview of the second generation biofuels in an Indian context and to describe the barriers to wider adoption of the biofuels. This review also aims to appraise the development of second generation biofuels industry in India summarizing the approximate costs for commercial scale plants from the literature along with major commercial and research programs in second generation fuels production in the country. This paper lists Indian research and development gaps that, once overcome, should assist in taking the industry forward. An objective of the review is to stimulate policy makers and industry to examine more closely the opportunities in second generation biofuels that are unique to India.
Due to the recent increases in petroleum prices and uncertainties concerning petroleum availability, there is renewed interest in non edible oil as fuels for diesel engines. In India, non edible oil like Jatropha, Pongamia, Mahua, Neem, Eucalyptus are being viewed as the future scope for biodiesel production. Biodiesel is one of the best available sources to fullfill the energy demand of India. The main problem associated with biodiesel is its poor oxidation stability. The oxidation stability of fats and oil and their product play an important role in determining the quality. It is defined as the resistance of oil/fats/biodiesel to degradation through oxidation with air which results in change of fuel quality. The exposure of oil, fats or biodiesel to atmosphere O , heat, heavy metal, light, porphyrims etc generate free radicals that form peroxide 2 radicals which subsequently lead to the formation of stable secondary products. These oxidation products will lead to gum formation and deteriorate the quality of the fuel and it cannot be used for engine operation. The objective of this paper is to investigate the induction period for various non edible oil using theoretical method to address their stability issue.
