This project addresses those technologies deemed most appropriate for small water systems to comply with the Jan '06 USEPA Arsenic Rule Maximum Contaminant Level (MCL). This volume reports on the bench-scale testing of of 4 technologies: ion-exchange processes, sorption kinetics, coupled sorbent-membrane processes and coupled coagulation-ballasted-sedimentation processes. Volume 2 will focus on results of the full-scale demonstration testing.

This is the second of two volumes that presents the results of a cooperative research effort between industry, academia, utilities to evaluate and demonstrate the treatment effectiveness of a wide range of technologies for arsenic removal. (Volume 1; ISBN: 1-58321-310-4; published Feb 2004) This volume focused on larger-scale in-situ demonstration testing of the major technologies reviewed in Volume 1, plus several additional technologies. Objectives were to describe the underlying chemical and physical controls over arsenic removal, consider the operational performance parameters and anticipate where improvements might occur. Sponsored by Arsenic Research Partnership, AWWRF, USEPA, and ACWA.

The two-volume reference work Chemical Technology and the Environment provides readers with knowledge on contemporary issues in environmental pollution, prevention and control, as well as regulatory, health and safety issues as related to chemical technology. It introduces and expands the knowledge on emerging "green" materials and processes and "greener" energy technology, as well as more general concepts and methodology including sustainable development and chemistry and green chemistry. Based on Wiley's renowned, Kirk-Othmer Encyclopedia of Chemical Technology, this compact reference features the same breadth and quality of coverage and clarity of presentation found in the original.

Bioremediation techniques for treating metals-contaminated soil and water are in an emerging state of development. Unlike organic compounds that can be broken down into harmless compounds such as CO2 and water, metals and their salts generally inhibit biological activity. They must be converted into more complex states, be sorbed, or undergo valence state changes before biodegradation by activated sludge treatment or other complex reactions such as air stripping can occur. This book introduces various treatment technologies and options for the bioremediation of metals. The chapters, written by researchers and practitioners from North America and Europe, represent the most recent compilation of state-of-the-art techniques and methods for metals biotreatment. These topics and more are addressed:

This report documents the activities performed and the results obtained for the arsenic removal treatment technology demonstration project at Charette Mobile Home Park (CMHP) in Dummerston, Vermont. The objectives of the project were to evaluate: (1) the effectiveness of an Aquatic Treatment Systems (ATS) arsenic removal system in removing arsenic to meet the new arsenic maximum contaminant level (MCL) of 10 ig/L, (2) the reliability of the treatment system, (3) the required system operation and maintenance (O & M) and operator skills, and (4) the capital and O & M cost of the technology. The project also characterized water in the distribution system and residuals produced by the treatment process.

Contamination of groundwater with arsenic is being considered a pervasive and critical issue in recent years. Large areas in India, Bangladesh, South East Asia, and other parts of the world are suffering from this problem. Arsenic Removal from Contaminated Groundwater presents a comprehensive discussion on various important issues, including state-of-the-art arsenic removal technologies, preparation and performance analysis of laterite, and scale-up issues and design of a household filter. It also expounds the potentiality of raw laterite and treated laterite as low-cost arsenic adsorbents. The efficiency of adsorbent capacity is evaluated using real arsenic contaminated groundwater collected from an affected area in West Bengal, India. The topic is an emerging area and most of the work presented has the potential of field application.

This report documents the activities performed and the results obtained from the first six months of the arsenic removal treatment technology demonstration project in the City of Wellman, TX. The main objective of the project was to evaluate the effectiveness of AdEdge Technologies' AD-33 media in removing arsenic to meet the new arsenic maximum contaminant level (MCL) of 10 microg/L. Additionally, this project evaluates (1) the reliability of the treatment system (Arsenic Package Unit (APU)-100CS-S-2-AVH), (2) the required system operation and maintenance (O & M) and operator skills, and (3) the capital and O & M cost of the technology. The project also characterizes the water in the distribution system and any residuals produced by the treatment process. The types of data collected include system operation, water quality parameters (both across the treatment train and in the distribution system), and capital and O & M cost.

Ion-exchange Technology I: Theory and Materials describes the theoretical principles of ion-exchange processes. More specifically, this volume focuses on the synthesis, characterization, and modelling of ion-exchange materials and their associated kinetics and equilibria. This title is a highly valuable source not only to postgraduate students and researchers but also to industrial R&D specialists in chemistry, chemical, and biochemical technology as well as to engineers and industrialists.
