1. 1. Spatial patterns of Dissolved Organic Matter in Swedish Surface Waters

   University essay from SLU/Dept. of Aquatic Sciences and Assessment

   Author : Anna Lackner; [2022]
   Keywords : Dissolved Organic Matter; Brownification; Digital Mapping; Soil Moisture; Stream Length;

   Abstract : Dissolved organic matter (DOM) in surface water has been widely studied, in part due to its significance for aquatic ecology and drinking water quality. Across Sweden, increases in the total organic carbon (TOC) concentrations and color of surface waters, known as brownification, were noted in the decades before and after year 2000, though recent analysis has found widespread DOM increase to have ceased after 2010.

3. 2. Activated Carbon for Treatment of Drinking Water - Removal of PFAS, DOC, UV254 and Odor Using Adsorption on Activated Carbon

   University essay from KTH/Kemiteknik

   Author : Beatrice Marsilius; [2022]
   Keywords : PFAS; DOC; UV254; activated carbon; adsorption; PFAS; DOC; UV254; aktivt kol; adsorption;

   Abstract : Tillgång till rent dricksvatten är en mänsklig rättighet och en viktig del av ett hållbart samhälle. Därför är det viktigt att säkerställa tillgången till samt kvaliteten av dricksvattnet som produceras i Sveriges vattenverk och i vattenverk världen över. READ MORE

4. 3. An implementation of an autonomous IoT system for real-time water quality monitoring with 4G and satellite connection : CatFish - Embedded systems

   University essay from Högskolan i Halmstad/Akademin för informationsteknologi

   Author : Johan Elfing; Daniel Persson; [2022]
   Keywords : CatFish; Embedded System;

   Abstract : This thesis is about implementing an Internet of Things system for measuring water quality in rivers and other aquatic environments with an autonomous water drone, where the data from various components are collected and sent wirelessly to the database in real-time. A Raspberry Pi is connected to the internet through a 4G modem and a wireless satellite communication connection called RockBlock for emergency calls and notifications. READ MORE

5. 4. Water quality and organic matter linkages in waters draining arable fields

   University essay from SLU/Dept. of Soil and Environment

   Author : Adam Eriksson; [2021]
   Keywords : Natural organic matter NOM ; particular organic matter POM ; dissolved organic matter DOM ; allochthonous; autochthonous; Florescence index FIX ; Freshness index BIX ; Humification index HIX ; SUVA 254; E2:E3; Spectral Slope; Observation fields; microbial matter; humic matter; unfiltered samples UF ; filtered samples F45 ;

   Abstract : This study investigated leaching of natural organic matter (NOM) in twelve Swedish arable fields with regards to the quality of dissolved organic matter (DOM) and particulate organic matter (POM), using Absorbance (UV-Vis) and fluorescence spectrometry (EEM). DOM is defined as organic matter (OM) 0.45 μm. READ MORE

6. 5. Framtidens vattenvård : en kvantifiering av internbelastningen av fosfor i Vansjön och Nordsjön i Norduppland

   University essay from SLU/Dept. of Aquatic Sciences and Assessment

   Author : Caroline Agrillo; Jens Fölster Jens Fölster; [2021]
   Keywords : fosfor; internbelastning; eutrofiering; syrebrist; aluminiumbehandling; biomanipulation;

   Abstract : En kvantifiering av internbelastningen av fosfor gjordes i de eutrofierade sjöarna Vansjön och Nordsjön i Norduppland genom fysiokemisk mätning av vattnet och fraktionsanalys samt inkuberingsanalys av sediment. Mycket låga syrehalter mättes under vintern 2021 medan vattnet var övermättat på syre under våren detsamma året. READ MORE
