Available in PDF, EPUB and Kindle. Book excerpt: Ninth International Conference on Water Pollution Research focuses on the methods, measures, and technologies involved in the treatment of wastewater, including the treatment of sludges and pollutants in bodies of water. The selection first offers information on carbon adsorption as an advanced wastewater treatment process, nitrification of surface water, and methods for measuring the thickenability of sludges. Topics include factors that influence adsorption, principle of biological nitrification, and characterization of sludges. The text also discusses the utilization of pulped newsprint as a conditioning aid in the vacuum filtration of a municipal sludge and the purification of pulp-bleaching wastewater with aluminum oxide. The publication reviews the properties and treatment of lime-algae sludge, concept of filterability, prediction of bacterial pollution in sea water, and the role of retained particles in deep bed filtration. The text also describes the immediate and continuous measurement of activated sludge quantity in sewage biological treatment tanks; comparative assessment of pollution loadings from non-point sources in urban land use; and wastewater control technology in steam-electric power plants. The book is a vital reference for readers interested in water pollution research.

This book was released on 2020-05-28 with total page 170 pages. Available in PDF, EPUB and Kindle. Book excerpt: Perturbations linked to the direct and indirect impacts of human activities during the Anthropocene affect the structure and functioning of aquatic ecosystems to varying degrees. Some perturbations involve stress to aquatic life, including soil and water acidification, soil erosion, loss of base cations, release of trace metals/organic compounds, and application of essential nutrients capable of stimulating primary productivity. Superimposed onto these changes, climate warming impacts aquatic environments via altering species’ metabolic processes and by modifying food web interactions. The interaction stressors is difficult to predict because of the differential response of species and taxonomic groups, interacting additively, synergistically, or antagonistically. Whenever different trophic levels respond differently to climate warming, food webs are restructured; yet, the consequences of warming-induced changes for the food web structure and long-term population dynamics of different trophic levels remain poorly understood. Such changes are crucial in lakes, where food web production is mainly due to ectotherms, which are highly sensitive to changes in their surrounding environment. Due to its remarkable physical inertia, including thermal stability, global warming also has a profound effect on groundwater ecosystems. Combining contemporary and palaeo data is essential to understand the degree to which mechanisms of stressors impact on lake biological communities and lake ecosystem functioning. The degree to which alterations can affect aquatic ecosystem structure and functioning also requires functional diversity to be addressed at the molecular level, to reconstruct the role different species play in the transfer of material and energy through the food web. In this issue, we present examples of the impact of different stressors and their interaction on aquatic ecosystems, providing long-term, metabolic, molecular, and paleolimnological analyses.

Download or read book Kinetics of Wastewater Treatment written by S. H. Jenkins and published by Elsevier. This book was released on 2013-10-22 with total page 185 pages. Available in PDF, EPUB and Kindle. Book excerpt: Kinetics of Wastewater Treatment contains the proceedings of a post-conference seminar held at the Technical University of Denmark, Copenhagen in 1978. Separating 10 papers presented in the seminar as chapters, this book begins with the conceptual basis of calcium phosphate precipitation in a denitrifying biofilm. The influence of pH and calcium ions upon phosphorus transformations in biological wastewater treatment plants; sewage treatment by activated sludge; orthokinetic flocculation of phosphate precipitates in a multicomponent reactor with non-ideal flow; and kinetics of phosphorus transformations in aerobic and anaerobic environments are then described. This text also looks into the chemical floc formation in wastewater treatment; temperature dependency of microbial reactions; the influence of some environmental factors on floc kinetics; kinetics of biological flocs; and two step precipitation of calcium phosphates.
