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 nanofiltration technique lies between ultrafiltration and reverse osmosis techniques, and it is considered a low-cost process and is capable of removing pesticides, organic matter, desalination of sea water, oil process and pollutants from industrial wastewater. However, the main challenge in implementation of nanofiltration membrane is its ability towards fouling and low performance at high temperature. The use of nanoparticles in the manufacturing of membranes allows for a high degree of control over membrane fouling. Nanoparticle-based membranes can be developed by assembling engineered nanoparticles into porous membranes or blending them with polymeric or inorganic membranes. This book covers topics from multiple ranges from manufacturing of nanofiltration membranes and their applications in wastewater treatment, drinking water treatment, and removal of pollutants, to addressing the fouling issues.

There are a number of treatment techniques that can effectively remove arsenic from drinking water. It is essential for utilities that are in the process of selecting an arsenic removal treatment technology to also identify the types of residuals that would be generated, their expected arsenic concentrations, and pre-treatment strategies that would be required prior to final disposal. This document provides utility guidelines for disposal of residuals containing elevated concentrations of arsenic.Originally published by AwwaRF for its subscribers in 2003 This publication can be purchased and downloaded via Pay Per View on Water Intelligence Online - click on the Pay Per View icon below

The objective of this project was to perform an overall feasibility analysis of point of use (POU) and point of entry (POE) systems for arsenic treatment, and to develop industry-wide recommendations for use of such systems as an alternative to centralized treatment, considering factors such as costs, process reliability, public perception, liability, and regulatory acceptance. The researchers also planned to assess water quality criteria that may limit the performance of POU/POE systems and determine at what size POU/POE treatment systems are cost-effective. Given the operational, financial, and implementation constraints of arsenic removal for very small systems, installation of "under the sink" POU devices may be a more viable and cost-effective option. The 1996 Safe Drinking Water Act amendments allow the use of POU and POE devices for compliance with certain MCLs (e.g., inorganics, organics, radionuclides) for small and rural systems. Since ingestion is the only exposure route of concern for arsenic, whole house treatment would not be necessary.

This new book explains advanced and emerging technologies for removing heavy metals from wastestreams and contaminated sites. Separation processes of this type are critical for meeting stringent regulations of priority pollutants, especially arsenic, mercury, and lead, which the text treats in depth. After explaining the chemistry of heavy metals a

The discussion on arsenic in the environment is complex and must grasp the importance of very many, mostly unrelated works on individual aspects. This volume represents one of the first comprehensive and interdisciplinary examinations into arsenic's behaviour in air, water, soils, sediments, plants and the human body. Based on state-of-the-art investigations into the global arsenic cycle, the related human toxicology and available remediation technologies, arsenic is assessed holistically in all the environmental compartments. Using the results of primary research, the authors offer concrete suggestions for risk reduction and management of environmental pollution that allow the reader to successfully tackle similar problems and find sustainable solutions. The book consists of three essential parts: Review of the current knowledge of arsenic behaviour in the environment (global biogeochemical cycles), toxicology, remediation techniques, immobilization technologies and environmental legislation Case studies for mining-related arsenic problems Discussion of mitigation and remediation technologies and approaches such as environmental education, hygiene training, backed by real experience and successful implementation in the study area In a highly coherent manner, the book makes use of 120 tables and figures, a large number of literature citations, and very detailed subject index (that encompasses references) to provide rapid and up-to-date access to all relevant information. Cross-references provide a great manoeuvrability between the chapters. The book delivers very insightful and hands-on approaches for graduate students and professionals working on arsenic questions not only in environmental science, but also in the fields of environmental engineering, medicine and social science.

The recently lowered arsenic maximum contaminant level (MCL) presents new challenges in the monitoring and treatment capabilities of drinking water utilities. This report provides advice to utilities and consultants as they monitor, make treatment modifications to control arsenic, and explain arsenic issues to the public. It overviews research on arsenic in drinking water with respect to health issues, occurrence, monitoring and treatment, and reviews the major treatment processescoagulation, lime softening, iron-manganese removal, ion exchange, activated alumina, reverse osmosis, nanofiltration, and augmented micro- or ultrafiltration.

An In-Depth Guide to Water and Wastewater Engineering This authoritative volume offers comprehensive coverage of the design and construction of municipal water and wastewater facilities. The book addresses water treatment in detail, following the flow of water through the unit processes and coagulation, flocculation, softening, sedimentation, filtration, disinfection, and residuals management. Each stage of wastewater treatment--preliminary, secondary, and tertiary--is examined along with residuals management. Water and Wastewater Engineering contains more than 100 example problems, 500 end-of-chapter problems, and 300 illustrations. Safety issues and operation and maintenance procedures are also discussed in this definitive resource. Coverage includes: Intake structures and wells Chemical handling and storage Coagulation and flocculation Lime-soda and ion exchange softening Reverse osmosis and nanofiltration Sedimentation Granular and membrane filtration Disinfection and fluoridation Removal of specific constituents Drinking water plant residuals management, process selection, and integration Storage and distribution systems Wastewater collection and treatment design considerations Sanitary sewer design Headworks and preliminary treatment Primary treatment Wastewater microbiology Secondary treatment by suspended and attached growth biological processes Secondary settling, disinfection, and postaeration Tertiary treatment Wastewater plant residuals management Clean water plant process selection and integration
