6. Fluorescence probes: towards automatic coagulant dosing
University essay from KTH/Hållbar utveckling, miljövetenskap och teknikAbstract : There is a current lack of accurate tools to determine the concentration of cyanobacteria in situ. Besides, cyanobacterial blooms have to be carefully monitored in reservoirs as they are more frequent because of climate change and can lead to potential released of toxins, along with other components.

7. Variability and regulation of the planktonic respiratory quotient in a eutrophic lake (Lake Vombsjön) in summer 2016
University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapAbstract : Bacterial respiration and biomass growth are important processes for carbon cycling in freshwater ecosystems and bacterial respiration is often quantified from measured O2 concentrations by using a respiratory quotient (RQ=O2 consumed to produce CO2, in moles) of 1. Recent studies have shown, however, that RQs can vary a lot in different aquatic ecosystems (0. READ MORE

8. Tracing the source of colourless carbon in an arctic lake on SW Greenland : Insights of organic matter origin from hydrogen isotope analyses of samples prepared using steam equilibration
University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskapAbstract : Lakes play an important role in the global carbon (C) cycle as they process carbon from terrestrial (allochthonous) and within lake (autochthonous) sources and may store C over long periods of time. Some arctic lakes contain high concentrations of dissolved organic carbon (DOC) that does not absorb light and thus remains colourless. READ MORE

9. THEORETICAL STUDY TO IMPROVE THE ENERGY BALANCE IN WASTEWATER TREATMENT PLANT : Investigation of microalgae photobioreactor in biological treatment step and open algal pond in reject water treatment in Uppsala and Västerås
University essay from Mälardalens högskola/Akademin för ekonomi, samhälle och teknikAbstract : The self-treatment system of nature cannot handle man-caused high rate water pollution on its own, therefore cleaning in wastewater treatment plant (WWTP) is necessary to avoid eutrophication – excessive enrichment of nature by nutrients. Current technologies applied in WWTPs are old, outdating and highly energy demanding, especially biological treatment step generally requires large amount of energy for aeration of water. READ MORE

10. Evaluation of using fine grain size Polonite® as sorbent for retaining phosphorus from wastewater.
University essay from Lunds universitet/Avdelningen för Teknisk vattenresursläraAbstract : To avoid eutrofication and excessive algal bloms it is necessary to reduce the phosphorus contents in wastewater. Previous wastewater treatment systems often have a good process for phosphorus reduction but in general not the ability to recycle the material and phosphorus for further utilisation after its use in wastewater treatment.
