1. Analysis of Methanol Based Chlorine Dioxide Production : An analysis of sodium chlorate reduction efficiency and investigation of salt cake filter wash on an SVP-LITE® system
University essay from Karlstads universitetAbstract : This work aimed to determine how effective an SVP-LITE® chlorine dioxide plant at Vallviks Bruk was running. This was done by determining the chemical consumption per unit of chlorine dioxide produced. The calculations relied upon online instrumentation that was manually validated. READ MORE

2. Optimization of a two-step anaerobic treatment of wastewater from the Pulp and Paper Industry
University essay from KTH/Industriell bioteknologiAbstract : Under de senaste 30 åren så har antalet massa- och pappersbruk minskat medan den totala produktionen av massa och papper har ökat. En högre produktion per bruk tillsammans med en hårdare miljölagstiftning, sätter ett högre tryck på vattenreningen på varje bruk. READ MORE

3. Cradle-to-Gate LCA of Water Treatment Alternatives : A case study performed for Norrvatten’s future waterwork expansion
University essay from KTH/Hållbar utveckling, miljövetenskap och teknikAbstract : Norrvatten is a municipal association which owns a water treatment plant capable of supplying good quality drinking water to the consumers in the associated neighbouring municipalities. After preliminary investigations for the future year of 2050, there were estimates which suggest a potential water quality degradation in the lake which supplies the raw water for treatment due to uncertain future climatic conditions and other forms of pollutions from the surrounding.

4. Neuroprotective effects of magnesium sulphate evaluated by fluoride resistant acid phosphatase, inorganic phosphate, lactate dehydrogenase and nitric oxide in rats with ischemia
University essay from Uppsala universitet/Institutionen för kvinnors och barns hälsaAbstract : Brain ischemia events are among the first three mortalities causes in the world associated with high treatments costs and in most cases some degree of permanent functional disability, thus it is necessary with new low cost and effective treatments. In the present study the potential neuroprotective effect of magnesium sulphate was evaluated by quantification of ischemic biomarkers: fluoride resistant acid phosphatase (FRAP), inorganic phosphate (Pi), lactate dehydrogenase (LDH) and nitric oxide (NO) in rats with global ischemia.

5. Spatial and temporal changes in microbial community composition in a full-scale woodchip bioreactor for treating mine water
University essay from Uppsala universitet/Institutionen för biologisk grundutbildningAbstract : Incomplete detonation of nitrogen-based explosives can lead to abundant levels of nitrate in mine groundwater. The possibility of reducing nitrogen levels from the wastewater through denitrification, anammox and DNRA has been investigated using a full-scale bioreactor. The bioreactor is situated subsurface and is filled with pine woodchips. READ MORE
