Download or read book Anaerobic Treatment of Mine Wastewater for the Removal of Selenate and its Co Contaminants written by Lea Chua Tan and published by CRC Press. This book was released on 2018-09-03 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Selenium (Se) pollution has led to several cases of severe aquatic ecosystem deterioration due to Se poisoning caused by bioaccumulation over time. However, the removal of selenate (SeO42-) from wastewater streams with co-contaminants has been largely considered as a black box in anaerobic biological systems using mixed consortia. This research aimed at addressing the effect of wastewater characteristics, i.e. co-contaminants such as nitrate (NO3-) and sulfate (SO42-), heavy metals and pH, on the biological reduction of SeO42- and evaluating process integration for Se-laden wastewater treatment with co-contaminants. This study demonstrated that the presence of co-contaminants can actually be beneficial for Se removal provided that the concentrations are carefully monitored and appropriate operating conditions and process configurations are used. The Se removal (total Se and SeO42-) efficiency increased by ~30% in the presence of NO3- and/or SO42- compared to systems with SeO42- alone. Additionally, an integrated process of an ion exchange (IX) column and bioreactors showed improved overall removal capacity for SO42- and total Se. The knowledge and information gained from this research can help in the advancement and application of biological processes, i.e. predicting of reactor performance, solving specific design or practical problems and implementing novel treatment techniques for Se-laden mine wastewater.

Download or read book Microbial Biofilms in Bioremediation and Wastewater Treatment written by Y.V. Nancharaiah and published by CRC Press. This book was released on 2019-10-18 with total page 415 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biofilms represent the natural living style of microbial communities and play a pivotal role in biogeochemical cycles and natural attenuation. Biofilms can be engineered for biodegradation and biotransformation of organic and inorganic contaminants, for both in situ bioremediation and ex situ treatment in bioreactors. This book focuses on microbial biofilms and their potential technological applications for sustainable development. It covers recent advances in biofilm technologies for contaminant remediation coupled to recovery of resources and serves as a complete reference on the science and technology behind biofilm mediated bioremediation and wastewater treatment.

Download or read book California s San Joaquin Valley and the Appalachian Region written by Tadlock Cowan and published by Nova Publishers. This book was released on 2006 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book undertakes a study of the San Joaquin Valley (SJV) and a comparison with the Appalachian region. The eight-county San Joaquin Valley, part of California's Central Valley, is home to 5 of the 10 most agriculturally productive counties in the United States. By a wide range of indicators, the SJV is also one of the most economically depressed regions of the United States. This book analyses the SJV's counties and statistically documents the basis of current socio-economic conditions. The book further explores the extent to which the SJV shares similarities with and differs from the Appalachian Regional Commission (ARC) area and a 68-county Central Appalachian sub-region which contains some of the most economically distressed counties in Appalachia. The book also examines the role of federal expenditures in the cities and counties of the SJV. In addition to examining socio-economic conditions in the SJV, the book provides analysis of water supply and quality issues especially those concerning agriculture, air quality concerns, and rail and shipping issues. It is fully indexed.

Download or read book Selenium in plants written by Elizabeth A.H. Pilon-Smits and published by Springer. This book was released on 2017-05-10 with total page 326 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book covers many facets of plant selenium (Se) accumulation: molecular genetics, biochemistry, physiology, and ecological and evolutionary aspects. Broader impacts and applications of plant Se accumulation also receive attention. Plant Se accumulation is very relevant for environmental and human health. Selenium is both essential at low levels and toxic at high levels, and both Se deficiency and toxicity are problems worldwide. Selenium can positively affect crop productivity and nutritional value. Plants may also be used to clean up excess environmental Se. Selenium in plants has profound ecological impact, and likely contributes to Se movement in ecosystems and global Se cycling.
