Available in PDF, EPUB and Kindle. Book excerpt: The zeolite ion exchanger clinoptilolite was investigated with the objective of optimizing its application to ammonia removal from wastewaters. The study included multiple cycle pilot plant operations at three municipal sewage treatment plants. Particular attention was given to cation interference with exhaustion performance and with minimum cost regeneration. The ammonia capacity of clinoptilolite was found to be nearly constant over the pH range of 4 to 8, but diminished rapidly outside this range. In regeneration the pH was critical in determining the NaCl requirements, a higher pH favoring lesser amounts of salt. However, at a pH over 12.5 zeolite attrition became excessive and exchanger makeup contributed significantly to operating costs. An average ammonia removal of 95.7% was obtained in demonstration studies on three municipal wastes have an NH3N content of about 20 mg/l. The cost of ammonia removal using clinoptilolite for a 10-mgd plant operating under these conditions was estimated to be $0.082/1000 gal. Ammonia removal down to less than 0.5 mg/l NH3−N is technically feasible, but only with shorter exhaustion runs and greater regenerant requirements.

This book was released on 2013-07 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: The U.S. Environmental Protection Agency (EPA) was introduced on December 2, 1970 by President Richard Nixon. The agency is charged with protecting human health and the environment, by writing and enforcing regulations based on laws passed by Congress. The EPA's struggle to protect health and the environment is seen through each of its official publications. These publications outline new policies, detail problems with enforcing laws, document the need for new legislation, and describe new tactics to use to solve these issues. This collection of publications ranges from historic documents to reports released in the new millennium, and features works like: Bicycle for a Better Environment, Health Effects of Increasing Sulfur Oxides Emissions Draft, and Women and Environmental Health.

Available in PDF, EPUB and Kindle. Book excerpt: A study was performed leading to the design of a system to treat municipal secondary effluent to potable quality and allow closed-loop water utilization. A comprehensive literature survey resulted in the acquisition of other 800 papers and reports on all advanced wastewater treatment processes. Summary evaluations were prepared for the important processes. A definition of a set of potable water quality criteria parameters was developed for the specific case of closed-loop water reuse. Mathematical models for performance and costs were compiled for the individual processes. A computer program in Fortran was assembled incorporating the cost and performance models of the processes as subroutines. The resulting computer program represents a mathematical model of the conceptual system and can be used to perform design calculations of optional combinations of the processes.

This book was released on 2018-12-17 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: Volume 4 of Reviews in Mineralogy was prepared to serve as notes for a short course on the Mineralogy and Geology of Natural Zeolites held in Seattle, Washington, November 4-6, 1977. The title of the short course reads Natural Zeolites; however, the subject matter treated in the course and reviewed here deals primarily with those zeolites that occur in sedimentary rocks and which have formed by authigenic or burial diagenetic processes. Unfortunately, only limited coverage has been given to the classical occurrences of zeolites--the megascopic crystals in the vugs and cavities of basalts and other basic igneous rocks. Our only justification is that since the late 1950s, almost all major efforts on zeolites have been directed towards the "sedimentary" occurrences, and it is these occurrences of zeolites in sedimentary rocks that are still unfamiliar to many geologists and mineralogists. It is our intention that this short course and these notes will play a small role in alleviating this unfamiliarity.

Download or read book Applications of New Concepts of Physical Chemical Wastewater Treatment written by W.W. Eckenfelder and published by Elsevier. This book was released on 2013-10-22 with total page 401 pages. Available in PDF, EPUB and Kindle. Book excerpt: Applications of New Concepts of Physical-Chemical Wastewater Treatment deals with novel concepts of physical-chemical wastewater treatment, with particular reference to their engineering applications. Topics covered range from ultrahigh rate filtration of municipal wastewater to the applicability of carbon adsorption in the treatment of petrochemical wastewaters, along with regeneration of activated carbon and dewatering of physical-chemical sludges. Comprised of 31 chapters, this volume begins with a discussion on the use of physical-chemical methods for the treatment of municipal wastes and for direct wastewater treatment. The following chapters focus on the interrelationships between biological treatment and physicochemical treatment; some problems associated with the treatment of sewage by non-biological processes; treatment of wastes generated by metal finishing and engineering industries; and the principles and practice of granular carbon reactivation. The precipitation of calcium phosphate in wastewaters is also considered, together with the use of surface stirrers for ammonia desorption from ponds. This book will be a valuable resource for chemists, engineers, government officials, and environmental policymakers.
