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.

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

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.

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.

Available in PDF, EPUB and Kindle. Book excerpt: Waste stabilization ponds are a long established technology that is steadily regaining popularity and is increasingly acknowledged as a high potential wastewater treatment option of the future due to ponds' capacity to enhance biodiversity and aesthetic value of the environment. Recent years have seen continuing development in the understanding of the fundamental processes involved in the various types of pond and in their practical implementation separately and in combination; there is also a new interest in devices such as baffles, recirculation systems and gravel filters. This growing complexity of pond technology and the demand for greater performance predictability require more in depth knowledge of the mechanisms involved and the effect of meteorological factors. All these topics were considered at IWA's 7th ponds conference after which participants submitted nearly a hundred papers for full peer review, which led to the selection of the 31 papers in this issue. The papers selected are grouped under the headings of: design and modeling of waste stabilization ponds; nutrient removal in waste stabilization ponds; upgrading waste stabilization ponds; advancement in waste stabilization ponds technology; and industrial and agricultural wastewater treatment. Together they provide an unrivalled insight into the state of the art in research into and application of waste stabilization ponds.

This book was released on 2020-01-15 with total page 668 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the basic principles for evaluating water quality and treatment plant performance in a clear, innovative and didactic way, using a combined approach that involves the interpretation of monitoring data associated with (i) the basic processes that take place in water bodies and in water and wastewater treatment plants and (ii) data management and statistical calculations to allow a deep interpretation of the data. This book is problem-oriented and works from practice to theory, covering most of the information you will need, such as (a) obtaining flow data and working with the concept of loading, (b) organizing sampling programmes and measurements, (c) connecting laboratory analysis to data management, (e) using numerical and graphical methods for describing monitoring data (descriptive statistics), (f) understanding and reporting removal efficiencies, (g) recognizing symmetry and asymmetry in monitoring data (normal and log-normal distributions), (h) evaluating compliance with targets and regulatory standards for effluents and water bodies, (i) making comparisons with the monitoring data (tests of hypothesis), (j) understanding the relationship between monitoring variables (correlation and regression analysis), (k) making water and mass balances, (l) understanding the different loading rates applied to treatment units, (m) learning the principles of reaction kinetics and reactor hydraulics and (n) performing calibration and verification of models. The major concepts are illustrated by 92 fully worked-out examples, which are supported by 75 freely-downloadable Excel spreadsheets. Each chapter concludes with a checklist for your report. If you are a student, researcher or practitioner planning to use or already using treatment plant and water quality monitoring data, then this book is for you! 75 Excel spreadsheets are available to download.
