The Activated Sludge (AS) Process is old technology but is still widely adopted worldwide for its convenience and simplicity: an impressive number (many hundred of thousands) of this kind of system are in operation. Occasionally, problems such as bulking and foaming occur, causing regulation violations and large investment is often required immediately to control them. For this reason, an intense research effort has been made during the last few decades to face these problems, and this report details the work undertaken by the IWA Specialist Group on Activated Sludge Population Dynamics. This Scientific and Technical Report describes the main reasons fslyuor the growth of the different filamentous microorganisms in activated sludge, and the biological molecular tools available today for the identification of the main biomass components. The wide range of experiences around the world is documented and the methods to avoid the proliferation of these organisms are presented and critically reviewed. Activated Sludge Separation Problems consists of seven chapters, presenting up-to-date technical and scientific aspects of these processes. Scientific and Technical Report No. 16

Anaerobic/aerobic (AnA) and completely aerobic (CA) laboratory-scale sequencing batch reactors operating on an acetate- and casamino acids-based synthetic wastewater were used to investigate the suitability of the AnA process for treating nutrient?deficient wastewaters in plants that have stringent effluent nutrient requirements. Of particular interest is the case where phosphorus (P)-deficient wastewaters with highly variable influent COD loading are being treated to meet both effluent TSS and P limits. At a 4 d mean cell residence time, AnA activated sludge had an approx. 20% lower P requirement than CA activated sludge. The difference between the end-of-aerobic cycle polyhydroxyalkanoate and carbohydrate contents of the sludges indicated that the AnAsludge used more influent carbon than the CA sludge for synthesis of non-P-containing storage products. The nitrogen requirements of AnA sludge were similar to those of the CA sludge. The AnA and CA SBRs were subjected to three different transient influent COD loading patterns that simulated (#1) daily COD Loading fluctuations, (#2) low weekend COD loading, and (#3) extended low COD loading periods. During the Loading Pattern #1 experiment, the average effluent soluble P concentrations for the AnA and CA SBRs were 0.4 and 1.0 mgP/L respectively, and complete removal of influent acetate was observed. During the Loading Pattern #2 experiment, the average effluent soluble P concentrations for the AnA and CA SBRs were 0.3 and 0.9 mgP/L respectively, but effluent acetate was detected during the first high COD loading cycle following the low weekend COD loading period. During the Loading Pattern #3 experiment, the VSS content of both reactors dropped sharply, effluent acetate breakthrough occurred, and effluent P concentrations exceeding 1 mgP/L were detected in both the AnA and CA SBRs. Based on these findings, the AnA process has potential as a technologically and economically superior alternative for wastewater treatment plants treating P-deficient wastewasters to meet stringent effluent TSS and P limits.

The most common activated sludge operating problems causing poor plant performance are related to solids separation. Especially common are bulking and foaming. Without a proper scientific foundation to support the efforts of wastewater treatment plant management, many attempts to thwart bulking and foaming have failed. Manual on Solving Activated Sludge Bulking, Foaming, and Other Solids Separation Problems provides the critical scientific and practical underpinnings needed to understand and combat these problems. The third edition of this flagship text is a comprehensive, concise guide to the microbiological and technical aspects of controlling all types of solid separation problems. The scientific theory is applied to real-world scenarios, greatly increasing the number of real-world examples of successful control methods. New information is also included on filamentous organism growth and its application in the control of sludge bulking and foaming. Now plant operators, regulators and wastewater engineers have a complete guide for battling these formidable design and operating problems.

Do your performance measures seek primarily to detect and control undesirable activities, rather than sharing and rewarding productive behaviour? Every organisation needs to measure its performance and that of the people it employs; David Jenkins shows you how to make more productive use of such measures. For measures to be accurate and reliable there are fundamental rules that need to be applied. Ignoring or misapplying them undermines performance and impedes the achievement of the corporate goal. For any enterprise, data must be available across the whole spectrum of activity in which it is engaged. The quality of that information will depend on the way it is measured. In some commercial organisations data is regularly gathered at local level. Instead of being used at this point, it is often fed into a corporate information system which, having recycled it, issues the result in a form that does not always meet needs. In Measuring Performance, David Jenkins examines the more traditional measures of performance and highlights their shortcomings as well as assessing the merits of the alternative approaches that are currently available. The book concludes with a step-by-step guide to reviewing the effectiveness of your organisation's existing systems for measuring performance and identifying ways of improving them.

One of the greatest treasures in the archives of the Welsh Industrial and Maritime Museum is the Hansen Collection, consisting of over 4500 negatives of shipping taken at Cardiff Docks between 1920 and 1975. Lars Peter Hansen, a native of Copenhagen, settled in Cardiff in 1891 and he and his third son Leslie established a photographic business in the docks; taking pictures of ships for sale to seamen and shipowners was an important part of their business. Following the retirement of Leslie Hansen in 1975, the museum purchased the negative collection. Its historical value cannot be overstated and this album is intended as a tribute to the Hansens, who through their work have bequeathed to Wales a pictorial record of shipping activity at the nation's premier port.

Gynaecological textbooks are divided into sections according to pathological diagnoses, not according to symptoms or symptom complexes. Students of gynaecology, because they initially acquire information from textbooks are conditioned by the organisation of these texts to think of gynaecology in terms of pathological entities rather than symptom complexes. Gynaecological patients, however, do not present complaining of endometriosis or endometrial malignancy or hypophyseal-ovarian dysfunction; rather, they present with symptoms such as 'pain low down in the tummy', 'bleeding from the front passage', or 'irregular periods'. This book attempts to help students of gynaecology (including everyone from students learning the subject for the first time, through family doctors, to doctors of all grades) to approach their patients as people as distinct from pathological entities, to listen to them, and to communicate with them. In order to help achieve this, the text is divided according to symptoms or related groups of symptoms. Within each division, pertinent questions are listed in the words that might be used in addressing a patient, followed by a key explaining the significance of the questions and a brief discussion of the problems under consideration. It is hoped that this apPfQach will facilitate the taking and interpretation of case histories, thus aiding differential diagnosis and clinical management, and will initiate the process of self-teaching. The book tries to emphasise that, especially in gynaecology, the same symptom (e. g. , heavy periods) may have a very different significance in different patients in terms of diagnosis and management.

Human Papillomavirus: Proving and Using a Viral Cause for Cancer presents a steady and massive accumulation of evidence about the role of HPV and prevention of HPV-induced cancer, along with the role and personal commitment of many scientists of different backgrounds in establishing global relevance. This exercise involved years of personal commitment to proving or disproving an idea that aroused initial skepticism, and that still has difficult implications for some. It remains one of the big successes of medicine that exploited both established medical science dating back to the nineteenth century and new molecular genetic science during a time of transition in medicine.

From 1875 to the present day, the Cardiff and Bristol Channel Incorporated Shipowners' Association has been the representative body for shipowners in Cardiff and other Bristol Channel ports. This study looks at some of the most representative periods in its history: the reaction of the Association to the proposal to build new docks in Barry in the 1880s, the Seaman's Strike in 1911, and the schism which split the Association in 1912-14. David Jenkins also reveals that a barrage across the estuary of the rivers Taff and Ely was first proposed as early as 1920. Nothing came of that proposal, but in 1929 a similar scheme was once more under consideration, comprising a dam with two locks across the tidal channel, between Penarth Head and Queen Alexandra lock.
