The use of constructed wetland systems for wastewater treatment : nitrogen transformation and indicator bacteria removalMcKersie, Sue A., University of Western Sydney, Hawkesbury, Faculty of Science and Technology January 1991 (has links)
Increasing demands for improved water quality in receiving waters, effluent reclamation and reuse have prompted wide interest in the use of wetlands for the treatment of wastewater. Over a four year period, domestic sewage effluent was treated using a range of gravel based, subsurface flow constructed wetland systems. Weekly samples at inlet and outlet points were assayed for suspended solids, biological oxygen demand, organic carbon, total kjeldahl nitrogen, ammonium, nitrate/nitrite, phosphorus, dissolved oxygen, temperature, pH and faecal coliform levels. The wetland system received secondary treated effluent for three years and primary settled effluent for one year. The potential of constructed wetland systems for nitrogen removal and potential pathogen reduction was investigated. Nitrogen removal was characterised by estimation of potential nitrification and denitrification rates within the system. Disinfection performance of the wetland system was assessed by enumeration of faecal indicator bacteria in the system influent and effluent, as well as with distance along the length of the system. The removal rate was estimated, considering influent and effluent faecal coliform concentrations as well as system hydraulic retention time and temperature. / Master of Science (Hons)

Beyond the fences : co-ordinating individual action in rural resource management through Landcare : a case study of managing non-point source discharges to water in Waikato, New ZealandRitchie, Helen, University of Western Sydney, Hawkesbury, Faculty of Environmental Management and Agriculture January 1998 (has links)
This study addresses the central problem of how the behaviour of individuals may be co-ordinated to manage collective natural resources, and in particular, to what degree this can be achieved through voluntary, community based means under a free market policy regime. This question was explored by researching how local groups known as Landcare, or Care groups, are managing waterways in Waikato, New Zealand, and specifically by examining their effectiveness in controlling non-point source contaminants to water originating from agricultural land.An action research approach was used to investigate research questions regarding what motivates actors to support activity to enhance water quality, the effectiveness of such activity in addressing non-point source discharges to water, and the equity issues which are associated with environmental management through Landcare. This study suggests that neo-liberal philosophies of governance, while favouring voluntary resource management, disregard the conditions which, in practice, underpin effective and equitable examples of this type of activity. A call is therefore made for a more active role for government, in directly supporting local action, in compensating for the impacts of free-market policies on natural resource use, and in facilitating the representation of the diversity of views in environmental management. Action research, participatory planning, and other learning based and communicative processes could be usefully employed to guide and inform such interventions / Doctor of Philosophy (PhD)

Living with water : traditional settlements of Chinese water townsGan, Tong. January 1999 (has links)
The present work is an attempt to analyze the traditional settlements of Chinese water towns with a particular emphasis on their urban structure and housing or the house form. / The historical background of the area is briefly discussed. Waterways and towns' developments, as well as examples of urban structure of the water towns are presented. The water towns' urban constituting elements, waterways, streets, bridges, quays, public squares are analyzed. The general principles of houses are studied, and case studies of typical houses are also included. / Finally, conclusions based on the study are presented.
