Download or read book Water Policy in Canada written by Mohammed H. Dore and published by Springer. This book was released on 2015-03-11 with total page 343 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book deals with the water policy and management in Canada. It discusses various problems and risks in the fresh and drinking water supply in the second largest country in the world. Mohammed Dore argues that water is underpriced and used wastefully in Canada. In selected case studies, he illustrates the major threats from human activity to Canadian freshwaters and drinking water resources, including manufacturing, mining, oil sands production, animal farming and agricultural use. Selected case studies include reviews of even dramatic incidences, e.g. the Walkerton tragedy of 2000, when 7 people were killed and 200 went onto permanent dialysis treatment because of water contamination with harmful pathogens. The book warns that wastewater treatment standards are often not sufficient, so that many drinking water resources are in peril of wastewater contamination. As most of the water resources are provincial responsibility, the book discusses the water management policies in the different provinces separately. Through a detailed discussion and statistical analyses, it can define water policy and management lessons that emerge from the investigated case studies. It ends by contrasting water policy and practice in Canada with the practice in some European countries.

Download or read book Choosing Disinfection Alternatives for Water Wastewater Treatment Plants written by Frank R. Spellman and published by CRC Press. This book was released on 1999-06-29 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: Safe drinking water and effluent have long been dependent on the large-scale use of chlorine. Process Safety Management (PSM) and the Risk Management Program (RMP), safety regulations now enforced by OSHA and EPA are leading to serious reconsideration of chlorination as the preferred disinfection method. Renewed concern about the safety of chlorination by-products is also driving water and wastewater specialists and plant personnel to consider alternatives to traditional chlorine application. Choosing Disinfection Alternatives for Water/Wastewater Treatment is a practical explanation of all available disinfection technologies in light of management criteria: legal compliance, plant safety, effuent quality, and cost. This text is designed for all who must understand and act on the challenge of finding safe and equally effective methods of wastwater and water disinfection besides traditional chlorination.

Download or read book Impact of Particles on Ultraviolet Disinfection of Bacteria in Water written by Raymond Edward Joseph Cantwell and published by . This book was released on 2007 with total page 624 pages. Available in PDF, EPUB and Kindle. Book excerpt: When UV light is applied to disinfect drinking water, particles in the water can conceivably protect embedded microorganisms from disinfection. Earlier studies have investigated how turbidity and particles affect light scattering, and particle-associated protection of cultured microorganisms. Little attention has been devoted to the ability of natural particles in water supplies to protect indigenous microorganisms. This thesis focuses on humic-coating of bacteria, the optical properties of particles and particle-related protection of indigenous microorganisms. A bench-scale proof-of-concept study found that both commercial (AHA) and aquatic humic acid (Suwannee River natural organic matter) appears to coat the surface of cultured bacteria hindering the effectiveness of UV disinfection. Both AHA and Suwannee River NOM were found to offer statistically significant (alpha = 0.05) protection of both E. coli and B. subtilis at concentrations of 50 and 120 mg/L. The concentrations of humic matter used in the study (10 to 120 mg/L) exceed those commonly found in surface waters. The bulk LV254 absorbance by particulate material in 10 surface waters was found to be the same order of magnitude as particles from the secondary effluent of a municipal wastewater treatment facility. This implies that since wastewater particles can offer protection to embedded microorganisms from UV light, it is possible for surface water particles to offer similar protection, at least in terms of the optical properties of the particle material. Particle-related protection of indigenous coliforms in untreated surface water from 3 sources (turbidity from 0.8 to 5.4 NTU) was observed with protection attributed to particles> 11 microm. However, despite this protection, at least 2.5-log inactivation of indigenous coliform bacteria was observed in all waters considered. In another untreated surface water (up to 1.3 NTU), no strong evidence of protection of indigenous coliforms or aerobic spores was found. A final objective of this study was to use 14 months of hourly UVT data to evaluate the USEPA's Ultraviolet Disinfection Guidance Manual recommendations for UVT data collection and analysis for design of UV systems. In terms of sampling frequency, both hourly and daily (but not weekly) UVT data collection provided reliable data for UV reactor design.

This book was released on 2017-11-22 with total page 231 pages. Available in PDF, EPUB and Kindle. Book excerpt: Several general books are available on ultraviolet light and its applications. However, this is the first comprehensive monograph that deals with its application to water and wastewater treatment. There is a rapidly growing interest in using UV light in water sanitation due to the increased knowledge of the potential health and environmental impacts of disinfection byproducts. Ultraviolet Light in Water and Wastewater Sanitation integrates the fundamental physics applicable to water and wastewater sanitation, the engineering aspects, and the practical experience in the field. The text analyzes the concerns associated with this application of UV light and brings together comprehensive information on the presently available UV technologies applicable to water and wastewater treatment including: lamp technologies, criteria of evaluation and choice of technology; fundamental principles; performance criteria for disinfection; design criteria and methods; synergistic use of UV and oxidants (advanced oxidation); and functional requirements and potential advantages and drawbacks of the technique. Ultraviolet Light in Water and Wastewater Sanitation is the only treatise currently available combining fundamental knowledge, recommendations for design, evaluations of performance, and future prospects for this application. Water and wastewater treatment professionals, water utility employees, governmental regulators, and chemists will find this book an essential and unique reference for a technology which has received growing regulatory acceptance.
