Download or read book Performance and Upgrading of Wastewater Stabilization Ponds written by U. S. Environmental Protection Agency and published by BiblioGov. This book was released on 2013-07 with total page 228 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: Ponds (lagoons) have been used for centuries with great success in the treatment of wastewater. Ponds created for treatment, known as stabilization ponds, model the physical and biochemical interactions that occur in natural ponds. Easy to build and manage, stabilization ponds can accommodate large fluctuations in flow, and provide results that are

Download or read book Performance Enhancement of Large Industrial Wastewater Stabilization Ponds written by Gary Davis Ramey and published by . This book was released on 1992 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: A 6-month-long, bench-scale simulation of an industrial wastewater stabilization pond (WSP) system was conducted to evaluate responses to several potential performance-enhancing treatments. The industrial WSP system consists of an anaerobic primary (1ry) WSP treating high-strength wastewater, followed by facultative secondary (2ry) and aerobic tertiary (3ry) WSPs in series treating lower-strength wastewater. The 1ry WSP was simulated with four glass aquaria which were fed with wastewater from the actual WSP system. The treatments examined were phosphorus supplementation (PHOS), phosphorus supplementation with pH control (PHOS+ALK), and phosphorus supplementation with pH control and effluent recycle (PHOS+ALK+RCY). The supplementary phosphorus treatment alone did not yield any significant change versus the CONTROL 1ry model pond. The average carbon to phosphorus ratio of the feed wastewater received from the WSP system was already 100:0.019 (i.e., 2,100 mg/l: 0.4 mg/l). The pH-control treatments (PHOS+ALK and PHOS+ALK+RCY) produced significant results, with 9 to 12 percent more total organic carbon (TOC) removal, 43 percent more volatile organic acid (VOA) generation, 78 percent more 2-ethoxyethanol and 14 percent more bis(2-chloroethyl)ether removal, and from 100- to 10,000-fold increases in bacterial enzyme activity and heterotrophic bacterial numbers. Recycling a 10-percent portion of the effluent yielded less variability for certain physicochemical parameters in the PHOS+ALK+RCY 1ry model pond, but overall there was no statistically-detectable improvement in performance versus no recycle. The 2ry and 3ry WSPs were also simulated in the laboratory to monitor the effect and fate of increased phosphorus loadings, as might occur if supplemental phosphorus were added to the 1ry WSP. Noticeable increases in algal growth were observed at feed phosphorus concentrations of 0.5 mg/l; however, there were no significant changes in the monitored physicochemical parameters. The effluent phosphorus concentrations from both the 2ry and 3ry model ponds did increase notably when feed phosphorus concentrations were increased from 0.5 to 1.0 mg/l.

Download or read book Waste Stabilization Ponds written by H. W. Pearson and published by IWA Publishing (International Water Assoc). This book was released on 2000 with total page 432 pages. Available in PDF, EPUB and Kindle. Book excerpt: The importance of pond technology is now recognized globally and indeed is undergoing a renaissance at the present time. It was therefore no surprise that scientists and engineers from over 25 countries presented their most recent findings at the Marrakech conference. The choice of Morocco was especially appropriate as it, like most countries of the Magreb, has actively endorsed and implemented the use of waste stabilization ponds as a preferred wastewater treatment technology. The need to reuse treated wastewater is a key component of the water cycle in such water-short regions, and the crucial role that ponds can play in the safe reuse of effluents, particularly for agriculture, has also been recognized and supported by active research at institutions all round the world. This issue contains a selection of the papers presented both in the oral and poster sessions at the conference and should prove very informative for those who wish to keep abreast of developments in the field. Among the 52 papers selected from the oral and poster sessions for these proceedings are work on the performance of ponds systems worldwide, pond microbiology, nutrient removal, pond sludges and sediments, pond design and modeling, high-rate ponds, and effluent reuse.

Download or read book Pond Treatment Technology written by Andrew Shilton and published by IWA Publishing. This book was released on 2006-03-01 with total page 494 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pond treatment technology is used in tens of thousands of applications serving many millions of people across the globe - why? Simply because it is efficient and effective. While pond treatment technology offers relative simplicity in its application, it incorporates a host of complex and diverse mechanisms that work to treat and cleanse polluted waters before their return to our environment. This book offers a comprehensive review of the pond technology field including the newest ideas and latest findings. Topics covered include: The physical, chemical and biological characteristics of the pond environment; A detailed review of pond treatment mechanisms and performance; Comprehensive guidance on pond design, operation and upgrade options; A range of chapters summarising new and emerging pond technologies; The integration of ponds with wetlands and aquaculture systems and their use as storage reservoirs; Special applications of pond technology in cold climates, for agricultural wastes and for treatment of stormwater. The objective of this book is to get this wealth of knowledge "out there" to the users to ensure the continuous improvement and ongoing success of this crucial technology.
