Download or read book Design of a Biological Phosphorus Removal Process for the City of Waukesha Wastewater Treatment Facility written by Adam Ewoldt and published by . This book was released on 2010 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this study is to analyze the current chemical phosphorus removal system and to compare it to a retrofit biological phosphorus removal system for the Waukesha Wastewater Treatment Plant. Phosphorus, an essential nutrient for all living things, causes serious eutrophication problems in receiving water bodies if not controlled. The Waukesha Wastewater Treatment Plant was chosen for an analysis of its existing chemical phosphorus removal system because data were available and there were no recent major modifications to the plant. The analysis of the phosphorus removal process was done to evaluate the feasibility of converting from a chemical phosphorus removal system to a biological phosphorus removal (BPR) system. This analysis found that a biological system appears to be feasible and promising based on analysis of the performance, cost, and environmental impacts. The benefits that could be acquired from this process outweigh the negatives. The analysis found that biological phosphorus removal could achieve the required 1 mg P/l effluent requirements for the plant. The benefits to the plant include: increased solids handling capacity resulting from a reduction of 255 tons per year of solids production from chemical additions, lower salinity in the effluent water, and reduced biosolids costs of $20,500 per year. The reduction in annual operational costs would result in a payback period of less than 3 years. Further investigation of this retrofit is justifiable for the City of Waukesha and the Waukesha Wastewater Treatment Facility managers.

This book was released on 1997-10-23 with total page 154 pages. Available in PDF, EPUB and Kindle. Book excerpt: FROM THE PREFACE Since Federal funding is scarce for massive upgrades, and/or complete new Wastewater Treatment Plants (WWTP) construction, treatment plant operators, superintendents, managers, city councils, boards, etc. must get more creative on funding and coordinating process equipment replacements. Contained herein you will find hints, tactics and procedures aimed at getting the "biggest bang for your public buck." During the 1970s and 1980s, through grants, the Federal Government paid 80% of costs to build new or expanded wastewater treatment plants, pumping stations and collection system renovations. The majority of the grants were to upgrade primary treatment facilities to secondary, and secondary to tertiary treatment status based on Clean Water Act regulations. If your facility was fortunate enough to receive grants, you were in good shape for approximately 20 to 30 years (depending on community growth rates). Since most wastewater treatment facilities are designed to last 20 years, many of the new or expanded facilities in the 70's and 80's are reaching the end of their service life. Some may have reached it sooner due to growth beyond the expected rate, inadequate preventive maintenance, or design inadequacies when built. Now you have identified problems with insufficient aeration capacity, equipment mechanical failure, insufficient pump station capacity, infrastructure deterioration, etc. and need to do something about it before you violate your NPDES permit (if you have not already). This equipment seems very costly to replace because you now must pay 100% opposed to 20% with the grants. Many WWTP are in need of replacement and/or upgraded equipment. The equipment itself is typically about 25% to 50% of the total project cost. This cannot be changed much. However, the remaining 50% to 75% (engineering, installation labor costs and project management) may be whittled down dependent on how active and creative the project coordinator (yourself) wants to be in the process. When EPA funded 80% of project costs in prior years, it was no big deal to have an "open pocketbook" attitude. Those days have changed forever and so have procurement procedures for projects. A Management Guide to Retrofitting Wastewater Treatment Plants is geared towards the managerial and administrative scope of a Lead Operator, Superintendent, Facility Manager type of Wastewater individual. All the junior college courses available, practical operator experience, and certification status will still not offer the opportunity to learn administrative and cost savings techniques (similar to operating a business). But soon, your job may demand these skills. This book is a handy reference for making the task of upgrading/retrofitting wastewater process equipment easier and less costly. It includes ideas for selling upgrade ideas to superiors, pre- and post-project activities, and certain management techniques useful for successful retrofitting or upgrading in past projects. This book should prove helpful to those who find themselves involved in retrofitting their facility, and need assistance on resolving facility problems, including treatment plant operators, superintendents, managers, city council members, and boards. It is also a valuable reference guide for municipal operations individuals who want to retain control of their facilities, but don't quite know how. It was written with the front line operator, superintendent, and manager in mind, in common operator language in order to allow easier understanding. It contains many tips and techniques which operators can implement immediately.

This book was released on 2021 with total page 247 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Anaerobic-anoxic-oxic (A2/O) is one of the most widely used processes in municipal wastewater treatment plants for simultaneous biological nitrogen and phosphorus removal. The A2/O process has many advantages, such as simple configuration and short hydraulic retention time (HRT), etc. In addition, it is easy to operate. Therefore, A2/O will be continuously chosen as the main option in all kinds of newly designed and built wastewater treatment plants. Though the A2/O process has been used widely, it has some inherent contradictions which are difficult to overcome. For example, the contradiction between substrate competition and SRT makes the high nitrogen and phosphorus removal unable to be achieved simultaneously. As a result, the removal efficiency of the system cannot be further improved. In the past 10 years in China, the wastewater quality very obviously changed with the improvement of living conditions. At present, municipal wastewater with a low C/N ratio is rather common in most countries in the world. The lack of a carbon source will make the inherent contradictions of the A2/O process becomes serious. Therefore, the conventional design parameters of the A2/O process are needed to adjust or the configuration of the A2/O process should change to fit the change of the wastewater quality. According to this, this book systematically describes how to improve the nitrogen and phosphorus removal efficiency of municipal wastewater with low C/N ratio, and effectively utilize the carbon resource in the influent of wastewater. This publication is useful for students, researchers and engineers whose major focus is municipal and the environment"--

Available in PDF, EPUB and Kindle. Book excerpt: FROM THE PREFACE In this time of dwindling budgets, increasing service needs, and increasing regulatory requirements, wastewater treatment professionals are continually called upon to upgrade their wastewater treatment plants. To do so efficiently and effectively, one must develop a clear approach to use in upgrading a plant and have the proper tools available to implement that approach. This book is meant to assist readers in developing and implementing their upgrading projects. First, Chapter 1 details the upgrading approach. The tools to be used are presented in Chapters 2 through 6. Finally, in Chapter 7, six case histories are presented to illustrate the plant upgrading techniques presented in the previous chapters. Through this book, the authors hope to assist readers in meeting their upgrade requirements, while making the most efficient use of the resources at hand.

This book was released on 2006-03-31 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: Enhanced biological phosphorus removal (EBPR) has been used for decades to remove phosphorus from municipal wastewater because it allows facilities to meet water quality goals while minimizing chemical consumption and sludge production. However, there is still substantial variability in both the practices applied to achieve EBPR and the level of soluble phosphorus removal achieved. The objective of this research project was to develop information that can be used to help municipal wastewater treatment plants more efficiently and cost effectively remove phosphorus through EBPR processes. This project included detailed analysis of routine water quality and operating data, field testing observations, and special studies conducted over the course of the project to evaluate the variability of EBPR, factors influencing EBPR performance, and the relationship between EBPR and the presence of glycogen accumulating organisms (GAOs).
