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 2011-09-20 with total page 1109 pages. Available in PDF, EPUB and Kindle. Book excerpt: New edition covers the latest practices, regulations, and alternative disinfectants Since the publication of the Fourth Edition of White's Handbook of Chlorination and Alternative Disinfectants more than ten years ago, the water industry has made substantial advances in their understanding and application of chlorine, hypochlorite, and alternative disinfectants for water and wastewater treatment. This Fifth Edition, with its extensive updates and revisions, reflects the current state of the science as well as the latest practices. Balancing theory with practice, the Fifth Edition covers such important topics as: Advances in the use of UV and ozone as disinfectants Alternative disinfectants such as chlorine dioxide, iodine, and bromine-related products Advanced oxidation processes for drinking water and wastewater treatment New developments and information for the production and handling of chlorine Latest regulations governing the use of different disinfectants For each disinfectant, the book explains its chemistry, effectiveness, dosing, equipment, and system design requirements. Moreover, the advantages and disadvantages of each disinfectant are clearly set forth. References at the end of each chapter guide readers to the primary literature for further investigation. Authored and reviewed by leading experts in the field of water and wastewater treatment, this Fifth Edition remains an ideal reference for utilities, regulators, engineers, and plant operators who need current information on the disinfection of potable water, wastewater, industrial water, and swimming pools.

Available in PDF, EPUB and Kindle. Book excerpt: Chlorine dioxide is evaluated as an alternative to chlorine for use in the disinfection of municipal wastewater. Bench-scale experiments in three topic areas are discussed: first, two methods for counting bacteria, membrane filter and most probable number are compared. Secondly factors affecting the relatively inadequate performance of chlorine dioxide, based on kill of coliform bacteria, are investigated. Thirdly, the two disinfectants are compared according to inactivation of viruses in secondary effluent. The information from these experiments will ultimately be used to develop a concept for a continuous reactor system that will be tested on a pilot scale.

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.
