Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Onsite wastewater management systems with irrigation are affordable and they are also easy to operate. Distribution of wastewater in public places such as lawns, parks, and golf courses is a common feature in wastewater reuse systems. However, it poses a health hazard to the public and people that are exposed to the irrigated wastewater when it is not adequately disinfected. This results in spread of infectious waterborne diseases such as gastroenteritis, cryptosporidiosis, and giardiasis. Among all disinfectants used in wastewater treatment, chlorine is the most common. It has many disadvantages such as the formation of a carcinogenic class of substance known as Trihalomethanes (THMs). A new alternative to wastewater disinfection in the form of a small packet has been developed by Avantec Technologies. Chlorine dioxide gas is produced when the packet containing reactants is exposed to moisture or immersed in water. Among several advantages of using chlorine dioxide for wastewater disinfection, the most significant is its ability to kill viruses and parasites. The objective of this project was to identify strategies to deliver the chlorine dioxide packets in a wastewater tank, and construct and evaluate prototypes for testing the device. Product design fundamentals such as problem decomposition function diagrams were used to identify the functions of the device. Mechanical concepts were identified and sketched using existing products, patent designs, and mind map techniques. A formal design of a delivery device was selected by iteration and improvement, and it was modeled in 3D form using Solid Edge- a mechanical modeling software application The delivery device comprises a top rack, a bottom rack, a wastewater drum, a circulating pump, and a wastewater storage tank. When a chlorine dioxide packet from the top rack is dropped into the bottom rack of the chlorine dioxide device, wastewater from the tank will be circulated into the wastewater drum enclosing the bottom rack. Chlorine dioxide gas is generated as a result and it mixes with the circulating wastewater to form a chlorine dioxide solution. The dropping of a chlorine dioxide packet would be timed and controlled according to wastewater level in the tank. The top rack portion of the delivery device design was further developed into a form prototype using suitable manufacturing processes. The top rack is an assembly of a set of components: (1) Cassette (2) ]ndexing plate (3) Retaining ring (4) Shaft and (5) Outer tube. The final goal of the project is to mass produce the chlorine dioxide delivery device and market it to the consumer at an affordable price. A fully functional control system to automate the top rack and a cost effective strategy to manufacture the device in large numbers will bring the project closer to its final goal.

This book was released on 2020-02-20 with total page 291 pages. Available in PDF, EPUB and Kindle. Book excerpt: Legionnaires' disease, a pneumonia caused by the Legionella bacterium, is the leading cause of reported waterborne disease outbreaks in the United States. Legionella occur naturally in water from many different environmental sources, but grow rapidly in the warm, stagnant conditions that can be found in engineered water systems such as cooling towers, building plumbing, and hot tubs. Humans are primarily exposed to Legionella through inhalation of contaminated aerosols into the respiratory system. Legionnaires' disease can be fatal, with between 3 and 33 percent of Legionella infections leading to death, and studies show the incidence of Legionnaires' disease in the United States increased five-fold from 2000 to 2017. Management of Legionella in Water Systems reviews the state of science on Legionella contamination of water systems, specifically the ecology and diagnosis. This report explores the process of transmission via water systems, quantification, prevention and control, and policy and training issues that affect the incidence of Legionnaires' disease. It also analyzes existing knowledge gaps and recommends research priorities moving forward.

Download or read book Antisepsis Disinfection and Sterilization written by Gerald E. McDonnell and published by John Wiley & Sons. This book was released on 2017-10-02 with total page 593 pages. Available in PDF, EPUB and Kindle. Book excerpt: Antisepsis, Disinfection, and Sterilization: Types, Action, and Resistance, by Gerald E. McDonnell, is a detailed and accessible presentation of the current methods of microbial control. Each major category, such as physical disinfection methods, is given a chapter, in which theory, spectrum of activity, advantages, disadvantages, and modes of action of the methods are thoroughly and clearly presented. Sufficient background on the life cycles and general anatomy of microorganisms is provided so that the reader who is new to microbiology will better appreciate how physical and chemical biocides work their magic on microbes. Other topics in the book include: Evaluating the efficacy of chemical antiseptics and disinfectants, and of physical methods of microbial control and sterilization. Understanding how to choose the proper biocidal product and process for specific applications. Classic physical and chemical disinfection methods, such as heat, cold, non-ionizing radiation, acids, oxidizing agents, and metals. Newer chemical disinfectants, including, isothiazolones, micro-and nano-particles, and bacteriophages as control agents. Antisepsis of skin and wounds and the biocides that can be used as antiseptics. Classic methods of physical sterilization, such as, moist heat and dry heat sterilization, ionizing radiation, and filtration, along with newer methods, including, the use of plasma or pulsed light. Chemical sterilization methods that use ethylene oxide, formaldehyde, or a variety of other oxidizing agents. A detailed look at the modes of action of biocides in controlling microbial growth and disrupting microbial physiology. Mechanisms that microorganisms use to resist the effects of biocides. The second edition of Antisepsis, Disinfection, and Sterilization: Types, Action, and Resistance is well suited as a textbook and is outstanding as a reference book for facilities managers and application engineers in manufacturing plants, hospitals, and food production facilities. It is also essential for public health officials, healthcare professionals, and infection control practitioners.

Download or read book Providing Safe Drinking Water in Small Systems written by Joseph Cotruvo and published by Routledge. This book was released on 2019-01-15 with total page 908 pages. Available in PDF, EPUB and Kindle. Book excerpt: The continued lack of access to adequate amounts of safe drinking water is one of the primary causes of infant morbidity and mortality worldwide and a serious situation which governments, international agencies and private organizations are striving to alleviate. Barriers to providing safe drinking water for rural areas and small communities that must be overcome include the financing and stability of small systems, their operation, and appropriate, cost-effective technologies to treat and deliver water to consumers. While we know how to technically produce safe drinking water, we are not always able to achieve sustainable safe water supplies for small systems in developed and developing countries. Everyone wants to move rapidly to reach the goal of universal safe drinking water, because safe water is the most fundamental essential element for personal and social health and welfare. Without safe water and a safe environment, sustained personal economic and cultural development is impossible. Often small rural systems are the last in the opportunity line. Safe Drinking Water in Small Systems describes feasible technologies, operating procedures, management, and financing opportunities to alleviate problems faced by small water systems in both developed and developing countries. In addition to widely used traditional technologies this reference presents emerging technologies and non-traditional approaches to water treatment, management, sources of energy, and the delivery of safe water.
