Abstract

Environmental issues throughout the world are thought provoking to our mankind. In this age of immense scientific progress and similarly the crisis and catastrophe of the issues of environmental disaster and energy sustainability, the question of novel separation processes comes into the mind’s horizon of a common man as well as a scientist. The alarming question of zero discharge norms is belittling mankind’s progress in science and technology. The world of challenge lies in the field of environmental engineering and the targeted vision of environmental regulations. Standing in such a critical juncture, mankind especially an environmental engineer is more poised towards novel separation processes mainly membrane separation processes. Within this wide and versatile domain of membrane science, nanofiltration has an imminent and far-reaching goal. This review deals with the vast application areas of nanofiltration in the field of desalination and groundwater treatment. The science of nanofiltration connotes to a persuasive definition-the separation of solid wastes whether it is organic or inorganic in view of a greater understanding towards efficiency and effectiveness of the particular membrane separation process. Nanofiltration , reverse osmosis, ultrafiltration and other membrane separation processes today is in the verge of new discoveries and dimensions of invention. Man’s struggle to fetch pure and clean drinking water which is pollution free and remediated has turned out to be one of the greatest social and scientific discoveries of our time. The challenges are immense as well as daunting. Scientific inventions and effective scientific pursuits is bringing our civilization to a new age of scientific validity. Clean water is the boon to a new age of scientific pursuit. The challenge to bring forward the importance of nanofiltration is daunting as well as visionary and it will surely go a long way in opening up new doors of innovation as well as intuition in years to come.

Abstract

Supply chain is an integrated area providing scope for enormous development and improvement in any business network. The paper discusses issues related to supply chain network in the context of Indian Railways (IR). A relationship of the existing supply chain network in India and USA has been attempted in brief. The key issues have been identified, segregated area wise and some potential solutions to these supply chain issues in the Indian context have been attempted and discussed. The methodology adopted in the present analysis was through carrying out an extensive literature survey, including study on the reports published by the Indian Railways and discussion with various stakeholders of the IR freight business. Some feedbacks were taken from the grass root levels through interactions with the railway workers in the ambala zone. The proposed solutions reflect the need to understand the key issues that can eventually lead to an active interest among the researcher community. Its active considerations by the IR can provide some cost cutting and esteemed benefits to its customers and stake holders.

Abstract

In the present study cold spraying was used to deposit and NiCoCrAlY coating on Fe-based Superfer 800H superalloy and coating was successfully deposited with cold spray process. As sprayed coating was tested for microhardness, thickness and microstructure. The hot corrosion behavior of the bare and coated superalloy is evaluated in Na2SO4-10% NaCl environment at 900°C under cyclic conditions. The microstructural characteristics of the corrosion products were investigated with XRD, SEM, EDAX and Elemental X-Ray Mapping. The cold sprayed NiCoCrAlY coating perform better as compare to bare superalloy against hot corrosion degradation. Dense coating structure obtained by the cold spray technique and protective oxide layer on the top are responsible for better performance of the coating.

Abstract

In this paper a numerical model for calculating plunger pump leakage is introduced. This model involves calculating the velocity profile for an annulus with the inner wall moving parallel to the outer wall. The calculated average velocity for the annular fluid is used to predict the fluid slippage. The new method for the slippage agrees with published formula at the same operating conditions. The numerical model is used to predict the fluid slippage at different operating conditions.

Abstract

Heavy metals present in waste water could affect adversely on aquatic life, human health and overall ecosystem. Therefore, nowadays more focus has been given for the use of agricultural waste as low cost adsorbents for the removal of heavy metals from waste water. In this paper, the studies on removal of Cu (II) from waste water on borasus flabellifer coir powder as adsorbent were investigated in a batch mode experiments. The agitation time, the adsorbent size, adsorbent dosage, initial copper concentration, and the effect of solution pH have been studied. The Freundlich model for Cu (II) adsorption onto borasus flabellifer coir powder was proved to be the best fit followed by Langmuir model and Tempkin model based on high regression coefficient R2 value. The adsorption kinetic behavior was best described by second order. The maximum percentage removal of metal efficiency was found to be 97.92 %. The results obtained in this study illustrate that borasus flabellifer coir powder is expected to be an effective and economically viable adsorbent for Cu (II) removal from industrial waste water.
