1. Finding ways of optimizing coagulant dosage, for a more sustainable wastewater treatment process
Master-uppsats, Lunds universitet/Kemiteknik (CI)Sammanfattning : The wastewater treatment process at Oatly consists of several treatment steps of which, two are chemical treatment steps involving coagulation followed by flotation to remove phosphorous and COD. The coagulant dosage is mainly determined based on the operator’s experience and supported using results from jar tests. LÄS MER
2. Continuous leaching of phosphorus from sewage sludge ash
Uppsats för yrkesexamina på grundnivå, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)Sammanfattning : The global demand for food is increasing. Different nutrients are used to increase growth in agriculture and are thus essential for the world ́s food supply. An important and common nutrient is phosphorus. It can be mined, in the form of phosphate, from phosphate rock. LÄS MER
3. How the Choice of Primary Treatment Affects the Biogas Potential of Primary Sludge
Master-uppsats, Lunds universitet/Kemiteknik (CI)Sammanfattning : The global heating has resulted in rising temperatures and more extreme weather conditions around the world. In combination with increasing energy demands, this has led to an increasing demand of renewable energy. One option is utilizing the wastewater to produce biogas. There-fore, wastewater can be seen as a resource rather than waste. LÄS MER
4. Reducering av antibiotikarester i akvatiskamiljöer : Alternativa behandlingsmetoder och vattenreningstekniker
Kandidat-uppsats, Högskolan i Gävle/Avdelningen för byggnadsteknik, energisystem och miljövetenskapSammanfattning : Antibiotikaresistens är en av de största globala utmaningarna i sjukvården och om den mängdantibiotika som används idag fortsätter att användas i framtiden riskerar det att kosta 10 miljonermänniskor om livet varje år från år 2050. Antibiotikarester i akvatiska miljöer ökar risken förspridning av antibiotikaresistenta bakterier. LÄS MER
5. Application of data-driven models in exploring cyanobacterial bloom risks in Lake Mälaren
Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknikSammanfattning : Cyanobacteria are a unique organism, a bacterium that develop photosynthesis, thus it contains chlorophyll, a pigment commonly associated to algae. For this reason, cyanobacteria are also known as blue-green algae. One of the secondary metabolites of cyanobacteria is cyanotoxin, a substance which is hepatoxic, neurotoxic, and dermatoxic. LÄS MER
