1. Modelling Micropollutant Removal Through Ozonation in Wastewater
Master-uppsats, Lunds universitet/Kemiteknik (CI)Sammanfattning : Proper management of water resources is a key to climate change adaptation and resilience in modern societies. Adequate treatment of wastewater is essential for ensuring the sustainability of the water cycle and the health of the environment and the ecosystems that inhabit it. LÄS MER
2. Synergies of nutrient fractions for fertilization in agriculture
Master-uppsats, SLU/Dept. of Biosystems and Technology (from 130101)Sammanfattning : A few countries are controlling the worlds phosphate reserves and this raw material is depleting at a faster rate. Most of the mined phosphate rock comes from Morocco and the Russia area which has unstable security. Studies shows that about 40% of potash export and 28% of nitrogen and phosphorus (P) fertilizer products comes from the Russia area. LÄS MER
3. Post-Denitrification on Sand Filter at Bromma Wastewater Treatment Plant
Master-uppsats, KTH/KemiSammanfattning : Examensarbetets syfte var att undersöka möjligheter till denitrifikation på sandfilter (SF) i industriell skala och hur det jämför sig med konventionella metoder för att uppnå denitrifikation och effekten av förändringen på processen vid Bromma reningsverk. Parametrar som undersöktes var rening av ammonium och nitrat, luftning, temperatur, pH, rening av fosfor, rening av organiskt material, rening av suspenderat material, förbigång av vatten vid SF och aktivslamanläggning (ASA), drifttider för SF:arna och total vattenbelastning på ASA och SF.

4. Skumproblematik i avloppsreningen vid Holmen Bravikens pappersbruk : Orsak och lösningsförslag
Master-uppsats,Sammanfattning : The treatment of industrial wastewater is an important measure to prohibit eutrophication and intoxication of lakes and oceans. Major industries often have location-basedwastewater treatment and to avoid undesired effluents it is essential to make it robust. LÄS MER
5. Fertiliser derived from human urine : novel media for alkaline urine dehydration
Master-uppsats, SLU/Dept. of Energy and TechnologySammanfattning : Every year, each human excretes approximately 4 kg of nitrogen, 1 kg of potassium and 0.3 kg of phosphorus through their urine. In conventional wastewater treatment, these nutrients are usually not recovered for agricultural production, although they can enhance plant growth. LÄS MER
