Abstract:
Studies of the populations of coliforms and faecal streptococci in sewage and sewer sediments have been carried out in Dundee. Samples have been obtained and tested by standard methods from five storm and five dry weather flow events. The temporal variation of bacterial populations and concentrations during both types of flow regimes found are discussed in relation to flow rates and other relevant parameters. Average daily variations of bacterial concentrations are proposed for dry weather flows. No consistent pattern of bacterial population variation was found for storm events. No interpretat

Abstract:
A facultative sewage lagoon in Inuvik, N.W.T. was studied in August (ice free) and November (ice covered) 1984. Emphasis was placed on the microbiological aspects and their relation to lagoon performance. Analyses performed included, pH, total alkalinity, total solids, suspended solids, volatile solids, COD and BOD5 determinations. The microbiological tests included total plate counts (20°C) and psychrotrophic counts (1°C). Results indicated that the Inuvik sewage lagoon system achieved removal efficiencies, ranging from 90% BOD5 removal in summer to about 80% in winter. The total bacterial co

Extensions to Doha South Sewage Treatment Works provided preliminary, primary, secondary and tertiary treatment for a design population of 100,000 persons, producing disinfected effluent for use in restricted municipal irrigation with digested sludge being conditioned and dewatered by plate pressing. Secondary treatment was designed to be non-nitrifying surface aeration activated sludge, and experience was gained in preventing partial nitrification by strict control of dissolved oxygen residuals. The works operated successfully to ensure a high quality of final effluent despite hydraulic overl

Abstract:
A “black-box” substrate removal model for predicting effluent pollution level in activated sludge treatment plants is presented. Reliability of the data acquired from batch and continuously operated systems has been studied. The dependence of the rate of substrate consumption on the quality and concentration of the substrates as well as on the adaptation and concentration of the microflora is shown by using a model sewage containing anion-active detergent as the sole carbon source. Prediction of the continuous operation on the basis of batch experiments is less tedious. The data acquired by th

This paper summarises the Scandinavian experience that chemical wastewater treatment gives “value for money” in the sense that such treatment gives a low construction volume per removed unit of Oxygen Consumption Potential (OCP) in the receiving water and a low energy consumption per unit of Oxygen Consumption Potential (OCP) removed. The OCP evaluation takes into consideration both the primary oxygen consumption caused by organic matter and ammonium as well as the secondary oxygen consumption from degradation of algae resulting from the discharge of nutrient.

During anaerobic digestion bacteria inside the digester require a carbon source for their growth and metabolism, sewage sludge was used as a carbon source in this study. The COD content was used to measure the disappearance of the substrate. COD content was reduced by 48.3% and 49% in the methanogenic and sulphidogenic bioreactors, respectively, while sulphate concentration was reduced by 40%, producing 70mg/L of hydrogen sulphide as the end product over the first 5-7 days.

As a first step in understanding the chemistry of toxic elements in sludged soil, this thesis presents a comprehensive model of their chemistry in the digester. A review of the literature had shown that heavy metals were likely to be held in 3 pools: as precipitated and detrital mineral phases 'Particulate'; as complexes with the flocculated biomass 'Biofloc'; and as complexes in solution 'Soluble'. A simple pragmatic fractionation procedure has been offered to separate these 3 pools based on their physical properties in water. A mass-balance between the pools showed that the 'Particulate' fra

Nitrogen pollution in marine waters is directly tied to human development – including agricultural runoff, atmospheric deposition, and urban wastewater effluents. After more than a century of urbanization, Hong Kong faces a major challenge in mitigating marine pollution, particularly nitrogen. Indeed, nitrogen pollution may be one of the primary causes of benthic ecosystem decline as evidenced by a contraction in the historical distribution of corals and seagrasses. Such ecosystems provide vital ecosystem services, not limited to nursery grounds for economically important fisheries. While the

Abstract:
This thesis examines the ecological consequences of sewage disposal in aquatic ecosystems. Sewage simultaneously represents a form of enrichment and a source of stress to a receiving system. Enrichment effects dominate when sewage loading does not exceed the capacity of the system to assimilate waste, as is presently the case in the St. Lawrence River. We developed a method to quantify the assimilation of sewage-derived organic matter by riverine biota, then used this method to examine the pathways by which sewage enhances secondary production in the St. Lawrence.

Abstract:
This chapter discusses the origins of Rollerball (1975) in the context of science-fiction cinema in the late 1960s and the first half of the 1970s, when the genre began a move to the centre of the commercial film business. It also took a distinctly dark turn as the impact of the Vietnam War, economic recession, the OPEC oil crisis, debates about overpopulation, environmental destruction, and, in the US, urban decay, and the political corruption revealed by the Watergate scandal worked their way into public consciousness. These concerns were all reflected in 1970s science fiction, and particularly percolated up in the decade's dystopian offerings. They also gave rise to the paranoia cycle of Hollywood thrillers that appeared in the late 1960s and early 1970s, in the context of which aspects of Rollerball can be viewed. The chapter then outlines some of the broader cultural debates William Harrison and Norman Jewison found themselves part of during the same period, principally concerns over increasing violence in professional American sport and society more generally, technological change, and growing corporate power.

"COST 68 bis was more extensive in scope than the initial project since it covered both treatment and use of sewage sludge. This meant that the topics included both the engineering and economics aspects of sludge processing at sewage works and the environmental aspects of sludge disposal particularly in regard to its utilisation as a fertilizer in agriculture. The use of sewage sludge in this way is important in most countries and it was recognised that co-ordinated research was desirable into both the possible adverse environmental effects of heavy metals and pathogens in sludges and the beneficial effects of plant nutrients in sludge. The problem of odour nuisance arising from the handling and spreading of sewage sludge was also recognised as an important subject-area for research. Under COST 68 bis, five Working Parties were established to co-ordinate the various areas of research. As a 'Concerted Action1, no direct funding was available from the European Commission to finance research projects on sewage sludge, each country being expected to contribute its own publicly-funded projects to the common ’pool*. COST 68 bis ran from 1977 to 1980(2) and was followed by an extension programme - COST 68 ter - which ran from 1981 to 1983(3). In 1983, it was decided to further extend this Concerted Action but to widen the range of research topics in the scientific programme to include animal manures. The renewed programme was designated COST Project 681 'Treatment and Use of Organic Sludges and Liquid Agricultural Wastes'. It is obvious that sewage sludges and farm manures have many aspects in common particularly with regard to handling and treatment techniques and to the environmental impact (e.g. odour) which can occur from their utilisation on land. On the other hand, from the administrative point of view, sewage sludge and farm manures are in two different 'worlds'. Sewage sludge is the general responsibility of public authorities while responsibility for disposing of animal manures belong mainly to the private farming sector. Funding for research on the two types of waste, even if from Government sources, is usually from different Departments and there is little cross-involvement of research scientists in the two sectors. Nonetheless, the COST 681 activity is attempting to promote some co-ordination of effort between the two research areas and, hopefully, this will result in mutual benefit to both those authorities responsible for sewage sludge treatment and those concerned with farm manures and their disposal. This joint Workshop on 'odours' is a good example of the type of co-operation, and sharing of information on a common problem, which can be of great mutual benefit to both sectors.
