Download or read book Proceedings of the Third Asia-Pacific Conference on Sustainable Energy and Environmental Technologies, Hong Kong, 3-6 December 2000 written by Xijun Hu and published by World Scientific. This book was released on 2001 with total page 716 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the rapid expansion of the Asia-Pacific economy in the last decade and the recovery after the recent crisis, severe demands will be placed on energy services and the environment. Coping with the volatile oil prices that persist in the market introduces an additional factor into the energy supply and demand equation, not just for countries in this region but also worldwide. Inevitably there will be implications for environmental issues too. The future will see a continuing challenge to balance growth with sustainability in the economic, social and environmental sectors. This conference, a sequel to the immensely successful APCSEET conferences held in Singapore and Australia, is aimed at meeting that challenge by addressing the pertinent issues related to sustainable energy and environmental protection. It provides a forum for participants from academia, industry and government agencies to interact, report on research in progress, and identify opportunities in the fields of sustainable energy and environmental technologies. The presentations include not only technical issues such as air pollution control, wastewater treatment, solid waste management, renewable energy and cleaner production, but also education and policy issues.

Download or read book Particle Deposition and Aggregation written by M. Elimelech and published by Butterworth-Heinemann. This book was released on 2013-10-22 with total page 458 pages. Available in PDF, EPUB and Kindle. Book excerpt: Particle Deposition and Aggregation: Measurement, Modelling and Simulation describes how particle deposition and aggregation can be measured, modeled, and simulated in a systematic manner. It brings together the necessary disciplines of colloid and surface chemistry, hydrodynamics, experimental methods, and computational methods to present a unified approach to this problem. The book is divided into four parts. Part I presents the theoretical principles governing deposition and aggregation phenomena, including a discussion of the forces that exist between particles and the hydrodynamic factors that control the movement of the particles and suspending fluid. Part II introduces methods for modeling the processes, first at a simple level (e.g. single particle-surface, single particle-single particle interactions in model flow conditions) and then describes the simulation protocols and computation tools which may be employed to describe more complex (multiple-particle interaction) systems. Part III summarizes the experimental methods of quantifying aggregating and depositing systems and concludes with a comparison of experimental results with those predicted using simple theoretical predictions. Part IV is largely based on illustrative examples to demonstrate the application of simulation and modeling methods to particle filtration, aggregation, and transport processes. This book should be useful to graduates working in process and environmental engineering research or industrial development at a postgraduate level, and to scientists who wish to extend their knowledge into more realistic process conditions in which the fluid hydrodynamics and other complicating factors must be accommodated.

Download or read book Colloids in the Aquatic Environment written by Th. F. Tadros and published by Elsevier. This book was released on 2013-10-22 with total page 313 pages. Available in PDF, EPUB and Kindle. Book excerpt: Colloids in the Aquatic Environment covers the proceedings of the International Symposium by the same title, held at the University College London on September 7-9, 1992, organized by the SCI Colloid and Surface Chemistry Group. This book is divided into 20 chapters and begins with an introduction to the fundamentals of surface structure and reactivity. The succeeding chapters deal with molecular mass determination of humic substances from natural waters, the biospecific mechanism of double layer formation, the dynamics of colloid deposition in porous media, and the evaluation of surface area and size distributions of soil particles. These topics are followed by discussions of the transport and capture of colloids; colloidal stability of natural organic matter; the hydrolytic precipitation and modeling ion binding by humic acids; and the thermodynamic aspects and photoelectrophoresis of colloids. Other chapters explore the colloidal transfer in several aquatic environments. The final chapters consider the mechanism of colloid detachment, speciation, partitioning, and stability. These chapters also look into a hybrid equilibrium model of solute transport in porous media in the presence of colloids. This book will be of great value to civil and environmental engineers.

Available in PDF, EPUB and Kindle. Book excerpt: Colloidal-collector interactions are of fundamental importance in separation and filtration technologies. Here, the effect of collector grains on the behavior of colloidal particles was studied in two different experimental systems, i.e., column studies with stationary collectors and batch mixing to study hetero aggregation. Polystyrene latex beads, 100 nm diameter, and soda lime glass beads, with two different diameters of 212-300 $\mu$m and 710-1180 $\mu$m, were employed as colloidal particles and collector grains, respectively. Column experiments were performed to understand fate of colloidal particles in the porous medium. There are three major phenomena that control colloidal transport in porous media: Deposition, aggregation, and straining. These three distinct types of particle dynamics in porous media were studied by adjusting physicochemical properties of colloidal suspension. Furthermore, the effect of washing the collector beads was studied. Batch experiments, in which known amount of collector grains are added to colloidal suspension with known concentration, are designed to investigate more collector-colloids interaction role in transport dynamics of colloidal particles. UV-Vis spectroscopy and dynamic light scattering techniques are employed to understand both deposition and aggregation of colloidal particles in the vicinity of collector grains. Results obtained by dynamic light scattering revealed that aggregation is the predominant factor in this colloidal system. The possible sources for this type of behavior are also tackled by undertaking controlled experiments. In the batch experiments, ions leaching from the surface of glass beads, effect of mixing, and glass beads presence are confirmed as the three major reasons behind the aggregation of colloidal particles.

Available in PDF, EPUB and Kindle. Book excerpt: Colloid deposition in granular media is relevant to numerous environmental problems. Classic filtration models assume a homogeneous pore space and largely ignore colloid aggregation. However, substantial evidence exists on the ubiquity of aggregation within porous media, suggesting that deposition is enhanced by it. This work studies the deposition process in relation to aggregate size and structure. We demonstrate that aggregation is induced at typical groundwater velocities by comparing the repulsive DLVO force between particle pairs to the hydrodynamic shear force opposing it. Column experiments imaged with high-resolution X-ray Computed Tomography were used to measure aggregate structure and describe their morphology probability distribution and spatial distribution. Aggregate volume and surface area were found to be power-law distributed, while Feret diameter was exponentially distributed with some flow rate dependencies caused by erosion and restructuring by the fluid shear. Furthermore, size and shape of aggregates are heterogeneous in depth, where a small number of large aggregates control the concentration vs depth profile shape. The range of aggregate fractal dimensions found (2.2-2.42) implies a high potential for restructuring and/or breaking during transport. Shear induced aggregation is not currently considered in macroscopic models for particle filtration, yet is critical to consider in the processes that control deposition.
