This book offers lucid treatment of fundamental concepts related to potential applications and prospects of different membranes for wastewater decontamination by removing heavy metals. Divided into four sections, it provides an overview of different sources of water contamination, their impacts on human health and the environment, and compares traditional methods used to nullify these impacts. Further, it covers different mature membrane technologies such as polymeric membranes, poly-ceramic membranes, carbon-based membranes and many more, followed by pertinent case studies. Features: Focuses on the removal of heavy metals using membrane-based technologies. Discusses pertinent criteria to select suitable membranes. Includes feasibility studies and applications of different mature and emerging membranes. Describes heavy metals' occurrence and transport in an aqueous system with an overview of the adverse effects. Reviews challenges and opportunities associated with using different membranes. This book is aimed at graduate students and researchers in materials science, water engineering and wastewater treatment.
The authors emphasize that an economy's competitiveness relies on purposive and intermeshed measures at the meta-, macro-, meso-, and micro- level and a multidimensional guidance concept consisting of competition, dialogue and shared decision-making which integrates the key groups of actors.
Despite a growing dairy industry in India, farmers’ lack of access to organized markets and institutional credit remains one of the major hindrances in improving the scale and productivity of dairying. Using data from a survey of 612 households from the state of Punjab, India, this paper evaluates farmers’ choices of dairy value chains and their financing mechanisms. The study finds that 62 percent of the sample farmers representing 69 percent of the total milk sales are connected with formal value chains driven by cooperatives, multinational companies and private domestic processors. Small dairy farmers are associated more with informal value chains but they are not excluded from the fo...
Heavy Metal Toxicity in Plants: Physiological and Molecular Perspectives highlights the various metal induced impacts on plants and adaptation strategies employed to avoid these stressful conditions. The volume comprise the chapters from the different areas ranging from latest biotechnological to omics approaches. This comprehensive volume emphasizes on the recent updates about the current research on the heavy metal stress in plant biology covering different aspects related to challenges and opportunities in the concerned field. This book is an attempt to bring together researchers who have been engaged in the area of stress signaling, crosstalk and mechanisms of heavy metal stress and shar...
Detailed hydro-geological investigations were carried out while implementing SCARPs in the Chaj Doab. These investigations yielded a data set of groundwater quality at different depths of the aquifers (spatial) especially in the SCARP-II saline zone. In MREP area, 138 public tubewells, having strainers from 30-35 m till 60-75 m depth of the aquifer, were installed during the 1970s to help meet the irrigation water demand at farm level. The MREP, who was made responsible for operation and maintenance of these deep tubewells, continuously monitored the performance of these tubewells as well. Therefore, the pumped groundwater quality data (temporal) of these spatially distributed tubewells was ...
