Biofiltration systems for the treatment of waste gas from industrial plants

[Abstract] Bord na Móna Environmental Ltd. has gained valuable experience over the years with the installation of over 500 biofilters, primarily in municipal and industrial wastewater treatment plants, food processing and more recently printing and coating applications. As a result, this paper will deal with the routes of successful biological air treatment and the pitfalls to avoid. Since the mid 1990s Bord na Móna have concentrated their efforts on process development for VOC and industrial applications. New applications include treatment of airstream containing high concentration of H2S, ammonia, VOC or indeed a combination of all three. The paper will cover new developments and new applications notably in solid waste composting plants, and in industrial applications. Success in biofiltration will be shown to be closely linked with in-depth analytical process engineering, accurate characterisation of waste gas streams, control of process conditions for optimisation of biological activity, and the physio-chemical properties of the filter media. Particular attention will be given to the successful application of biofilters for extremely high concentrations of sulphur compounds, up to 5000mg/m3, and the increasing use of biofilters for VOC elimination

Harnessing Technology: new modes of technology-enhanced learning: a case study series

This report presents the outcomes and conclusions from a series of 18 case studies exploring the innovative use of technology for learning and teaching using new modes of technology

Towards standardisation of no fault found taxonomy

There is a phenomenon which exists in complex engineered systems, most notably those which are electrical or electronic which is the inability to diagnose faults reported during operation. This includes difficulties in detecting the same reported symptoms with standard testing, the inability to correctly localise the suspected fault and the failure to diagnose the problem which has resulted in maintenance work. However an inconsistent terminology is used in connection with this phenomenon within both scientific communities and industry. It has become evident that ambiguity, misuse and misunderstanding have directly compounded the issue. The purpose of this paper is to work towards standardisation of the taxonomy surrounding the phenomena popularly termed No Fault Found, Retest Okay, Cannot Duplicate or Fault Not Found amongst many others. This includes discussion on how consistent terminology is essential to the experts within organisation committees and, to the larger group of users, who do not have specialised knowledge of the field

Issues Surrounding the Widespread Adoption of Learning Management Systems: an Australian Case Study

In: A.J. Kallenberg and M.J.J.M. van de Ven (Eds), 2002, The New Educational Benefits of ICT in Higher Education: Proceedings. Rotterdam: Erasmus Plus BV, OECR ISBN 90-9016127-9This paper discusses the evolution of the online learning environment at Murdoch University, in Perth, Western Australia, beginning in 1997, and continuing, in late 1998, with the adoption of the WebCT Learning Management System. WebCT adoption was supported by central funds through the Murdoch Online Mainstreaming (MOLM) Project, which set out to establish online teaching and learning as a mission critical activity of the University, but also to give academics control over their material. The rationale behind the MOLM project is described, in terms of a model of adoption of technological innovations. The Murdoch Online Mainstreaming Project met its objectives. Currently 223 units are available through WebCT, with the highest uptake in the Schools of Commerce, Law and Information Technology. Over the last twelve months, 9364 individual students have been enrolled in a WebCT course. This is over three quarters of the students enrolled at the University. However, despite demonstrable and enthusiastic uptake by teaching staff and students, the MOLM initiative encountered significant problems in 2001, when the initial two years of project funding was exhausted. It then became apparent that the University’s strategic directions were not well-coupled with its budget allocation processes, with the result that ongoing funding was not initially available to support online learning. The paper discusses various approaches taken to secure ongoing funding for online learning, including a comprehensive, user-pays model, which was eventually rejected in favour of a central allocation. The paper concludes with a discussion of recent moves by the University to radically redesign the ways in which it conceives of a unit of study, both in pedagogical and administrative terms

Synthetic and Mechanistic Investigations of Organoplatinum Chemistry

The addition of PMe2Ph to [ Pt2Cl4(PMe2Ph)2] at low temperatures produces the ions [PtCl (PMe2Ph)3]+ and [PtCl3(PMe3Ph)]- as major products, as well as some of the expected [PtCl2(PMe2Ph)2]. Less ionic material is produced from the addition of PBu3 to [Pt2Cl4(PMe2Ph)2] and PMe2Ph to [Pt2Cl4(PBu3)3] , and none at all from the addition of PBu3 to [Pt2Cl4(PBu3)2] . Ionic materials are also produced in the reactions of PMePh2 and SPMePh2 with [Pt2Cl4(PBu3)2] , and of PBu3 and SPBu3 with [Pt2Cl4(PMePh2)2]. The nature of the neutral ligands involved has a profound effect on the course of the reactions

Big Five Personality Traits and Political Orientation: An Inquiry into Political Beliefs

Personality research centered on the Big Five personality traits has heavily impacted our understanding in regards to what forces orient a person on a political spectrum. Examining how personality differences interact with political orientation, this research seeks to provide information on what makes someone either more or less likely to be liberal or conservative based on their temperament. In this paper, previous personality research is synthesized into one discussion, centered on what the effects of each trait are and how they impact political orientation, the heritability of personality, and what implications there are for such research in the realm of political psychology and political discourse in general

Constructing the Panama Canal: A Brief History

Seeking to commemorate the construction of the Panama Canal, an engineering marvel widely considered a contender for the eighth wonder of the world, this article attempts to retell the story of the Canal\u27s construction by synthesizing a narrative centered on the Canal under French and American leadership, worker segregation, and labor conditions at the Isthmus
