1. 1. In the Pipe or End of Pipe? : Transport and Dispersion of Water-borne Pollutants and Feasibility of Abatement Measures

   Författare :Christoffer Carstens; Vladimir Cvetkovic; Auli Niemi; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Contaminant transport modelling; Groundwater; Dispersion; Wave power; Eutrophication;

   Sammanfattning : Eutrophication is one of the key environmental problems of today, both in terms of complexity and magnitude. For the Baltic Sea (BS), eutrophication is an acute problem, leading to hypoxic conditions at the bottom; a situation that is sustained and amplified, when phosphorus is released from hypoxic sediments.

4. 3. Quantitative Understanding and Prediction of Lake Eutrophication

   Författare :Andreas Christoffer Bryhn; Lars Håkanson; Thorsten Blenckner; Gesa Weyhenmeyer; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Freshwater ecology; Limnisk ekologi;

   Sammanfattning : Many lakes around the world have been exposed to increased nutrient input from anthropogenic sources such as sewage discharge and runoff from fertilised agricultural areas. This has led to eutrophication, manifested as intensified algal blooms, murky waters, oxygen depleted lake bottoms, and alterations of considerable parts of the foodweb. LÄS MER

5. 4. NOx Abatement Technique for Marine Applications - Improved SCR Systems

   Författare :Mathias Magnusson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sulfur dioxide; Human-Machine system; NOx reduction; Water; urea-SCR catalyst; Marine applications; Human element.;

   Sammanfattning : Growing awareness of the environmental implications of emissions of nitrogen oxides (NOX), such as eutrophication and acidification on land and at sea, has contributed to the development of more stringent international NOx legislations within the framework of IMO, with the most stringent legislation, Tier III, representing a NOx reduction of approximately 80% compared with today’s engines. Several NOx abatement technologies are available on the market, the most effective of which may be Selective Catalytic Reduction (SCR). LÄS MER
