Washing and Dewatering of Different Starches in Pressure Filters
Acta Universitatis LappeenrantaensisURN:ISSN:1456-4491 (10.11.2006)The main objective of this thesis was togenerate better filtration technologies for effective production of pure starchproducts, and thereby the optimisation of filtration sequences using created models, as well as the ... -
Water chemistry and greenhouse gases emissions in the rivers of the “Third Pole”/“Water Tower of Asia”
Acta Universitatis Lappeenrantaensis (Lappeenranta University of Technology, 11.08.2017)With global warming, annual temperature on the Tibetan Plateau, where is also known as the “Third Pole” and the “Water Tower of Asia”, has increased significantly during the last decades. Climate change on the Tibetan ... -
Water circulations for effective bleaching of high-brightness mechanical pulps
Acta Universitatis Lappeenrantaensis (Lappeenranta University of Technology, 27.11.2009)The amount of water available is usually restricted, which leads to a situation where a complete understanding of the process, including water circulations and the influence of water components, is essential. The main aim ... -
Water-energy nexus for waste minimisation in the mining industry
Acta Universitatis Lappeenrantaensis (Lappeenranta-Lahti University of Technology LUT, 06.07.2022)Water and energy use are intrinsically intertwined and are critical factors influencing mining sustainability. The rising demand for metals and the decrease of ore grade cause the increase of water volume required and the ... -
Weldability of high strength aluminium alloys
Acta Universitatis Lappeenrantaensis (Lappeenranta University of Technology, 01.12.2015)The need for reduced intrinsic weight of structures and vehicles in the transportation industry has made aluminium research of interest. Aluminium has properties that are favourable for structural engineering, including ... -
Welding time models for cost calculations in the early stages of the design process
Acta Universitatis LappeenrantaensisURN:ISSN:1456-4491 (2000)It is generally accepted that between 70 and 80% of manufacturing costs can be attributed to design. Nevertheless, it is difficult for the designer to estimate manufacturing costs accurately, especially when alternative ... -
Wet Oxidation of Concentrated Wastewaters: Process Combination and Reaction Kinetic Modeling
Acta Universitatis LappeenrantaensisURN:ISSN:1456-4491 (2003)The accumulation of aqueous pollutants is becoming a global problem. The search for suitable methods and/or combinations of water treatment processes is a task that can slow down and stop the process of water pollution. ... -
Wet oxidation of recalcitrant lignin waters: Experimental and kinetic studies
Acta Universitatis Lappeenrantaensis (Lappeenranta University of Technology, 21.12.2009)The dissertation is based on four articles dealing with recalcitrant lignin water purification. Lignin, a complicated substance and recalcitrant to most treatment technologies, inhibits seriously pulp and paper industry ... -
What constrains the sustainability of our day-to-day consumption? A multi-epistemological inquiry into culture and institutions
Acta Universitatis Lappeenrantaensis (Lappeenranta-Lahti University of Technology LUT, 27.01.2021)Environmental crises unfold. The conditions for life are threatened. Unsustainable ways of living pervade; change is called for. As consumption is an intrinsic part of the system in crisis, it can provide a window of ... -
Wind Farm Layout Optimization: Project Economics and Risk
Acta Universitatis Lappeenrantaensis (Lappeenranta-Lahti University of Technology LUT, 01.09.2023)Wind energy is an integral resource for the transition of the energy sector to cleaner electricity production. While the advantages, such as its fuel- and water-free production, are evident, at present the economic viability ... -
Wind Turbine Direct-Drive Permanent-Magnet Generator with Direct Liquid Cooling for Mass Reduction
Acta Universitatis Lappeenrantaensis (Lappeenranta University of Technology, 25.06.2014)Today’s electrical machine technology allows increasing the wind turbine output power by an order of magnitude from the technology that existed only ten years ago. However, it is sometimes argued that high-power direct-drive ... -
Working fluid selection and design of small-scale waste heat recovery systems based on organic Rankine cycles
Acta Universitatis Lappeenrantaensis (Lappeenranta University of Technology, 10.12.2014)Demand for the use of energy systems, entailing high efficiency as well as availability to harness renewable energy sources, is a key issue in order to tackling the threat of global warming and saving natural resources. ... -
