Improvement of the Ozonation Process Through the Use of Static Mixers


Book Description

Among the known disinfectants, ozone has been demonstrated to be very effective in inactivating protozoans. Current and proposed regulations impose additional treatment requirements for Cryptosporidium parvum. These regulatory trends tend to place more stringent performance demands on disinfection systems and have therefore increased the need for improvements in the design. The static mixer offers one alternative method for improving the efficiency of the dissolution of ozone and optimizing its use in the disinfection process.The overall objective of this research was to quantify the potential benefits of ozone application through the use of static mixers in terms of increased transfer efficiency, disinfection capacity, and enhanced chemical reactions at laboratory-, pilot-, and full-scale systems. Specific goals were to identify and quantify the effect of several water quality parameters and environmental/engineered factors on the disinfection capacity of the ozone-static mixer system and assess bromate formation under optimum conditions for microbial inactivation.Originally published by AwwaRF for its subscribers in 2003 This publication can also be purchased and downloaded via Pay Per View on Water Intelligence Online - click on the Pay Per View icon below







Ozone in Drinking Water Treatment


Book Description




Applied Bioengineering


Book Description

A comprehensive overview of the topic, highlighting recent developments, ongoing research trends and future directions. Experts from Europe, Asia and the US cover five core areas of imminent importance to the food, feed, pharmaceutical and water treatment industries in terms of sustainable and innovative processing and production. In the field of enzyme engineering, they summarize historic developments and provide an overview of molecular enzyme engineering, while also discussing key principles of microbial process engineering, including chapters on process development and control. Further sections deal with animal and plant cell culture engineering. The final section of the book deals with environmental topics and highlights the application of bioengineering principles in waste treatment and the recovery of valuable resources. With its cutting-edge visions, extensive discussions and unique perspectives, this is a ready reference for biotechnologists, bioengineers, bioengineers, biotechnological institutes, and environmental chemists.







Chemical Water and Wastewater Treatment III


Book Description

Exactly ten years ago an experiment was started that proved to be extremely successful: the First Gothenburg Symposium. Its intent was to further the under standing of all processes pertaining to Chemical Water and Wastewater Treatment, and to bring together specialists working in basic research as well as in devel opment and administration. Now, the Proceedings of the Sixth Symposium are about to be published, clearly proving that there is a need for this forum. They dramatically illustrate the significance and the dynamic development of the topics of these symposia. It is fascinating to witness that in this time of reduced economic growth or even standstill, the environmental drive has not come to a halt, as many anticipated or feared. It is accepted more and more that the protection of the environment, a constant theme in all the Gothenburg Symposia, is not only a topic to be dealt with in times of affluence; it is now also seen as an instrument for cutting ex penditure, saving energy, and husbanding resources. The ever growing interest in these Gothenburg Symposia, documented by the large number of contributions the scientific panel received and the large demand for the books of this series that always exceeds the supply, testify to this commitment.




Water, wastewater and soil treatment by advanced oxidation processes (AOPs)


Book Description

Advanced Oxidation Processes (AOPs) have gained attention rapidly worldwide since they have been proven to be effective in the removal of wide spectrum of organic and inorganic contaminants from water and soil. However, the issues related to the formation of oxidation intermediates which may be more toxic than parent compounds as well as the operating costs are the main obstacles to a wider spread at full scale. This volume is addressed to researchers and professionals with a background in environmental science and engineering. The objective is to provide them with knowledge about AOPs related applications such as fundamentals and technology, analytical characterization of emerging contaminants and oxidation by products, ecotoxicity and biodegradability tests, urban and industrial wastewater treatment, sludge treatment and reduction, soil treatment, solar driven AOPs.







Water Supply


Book Description

This new edition of a classic text has been significantly expanded to cover the most current issues and international standards are examined in-depth, with detailed coverage of WHO, European, UK and US standards, organisations and practice. Written with the postgraduate and professional water engineer in mind, this text will also be essential reading for undergraduates studying water engineering.COMPREHENSIVE coverage of all aspects of public water supply and treatment for a worldwide market * INCLUDES more coverage of US, European and WHO standards and practice * COVERS important current topics such as EIA and cryptosporidium outbreaks




Chemical Degradation Methods for Wastes and Pollutants


Book Description

Chemical Degradation Methods for Wastes and Pollutants focuses on established and emerging chemical procedures for the management of pollutants in industrial wastewater and the environment. This reference offers an in-depth explanation of the degradation process, mechanisms, and control factors affecting each method, as well as issues crucial to the application of these approaches in real-world treatment sites. It examines ten of the most common and useful chemical technologies for environmental remediation and sanitation of industrial waste streams and offers implementation guidelines and examples of remediation strategies that are crucial to effective wastewater cleansing.
