  1. 1. Modelling Micropollutant Removal Through Ozonation in Wastewater

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Maximiliano Andrés Oportus Foster; [2023]
    Keywords : Micropollutants; water reuse; wastewater treatment models; ozonation; computer modeling; water and environmental engineering; Technology and Engineering;

    Abstract : 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. READ MORE

  2. 2. Yearly distribution and composition of per- and polyfluoroalkyl substances (PFAS) in Luleå wastewater treatment plant

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Moa Sjöberg; [2023]
    Keywords : PFAS; WWTP; Wastewater treatment; Consumer products; Precursors;

    Abstract : PFAS (per- and polyfluoroalkyl substances) are a large group of substances that are used in a large variety of products because of their unique water and dirt repellent properties. The substances are extremely persistent and can spread over large distances in groundwater, surface water, and in the air, which makes them an environmental and a health concern. READ MORE

  3. 3. Evaluation of pharmaceutical removal in seven WWTPs : Efficiency of different treatment technologies

    University essay from Stockholms universitet/Institutionen för miljövetenskap

    Author : Viktor Munkhammar; [2023]
    Keywords : Pharmaceuticals; wastewater treatment plant; removal efficiency; biological treatment; ozonation;

    Abstract : Wastewater treatment plants (WWTPs) are originally not constructed to remove pharmaceuticals from the wastewater. Biological treatment technologies used in many WWTPs today, e.g., activated sludge, MBBR and trickling filters, can, however, remove some pharmaceuticals well. READ MORE

  4. 4. Reduction of Acrylamide in Reject Water from Sludge Dewatering

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Martina Aspegren; [2023]
    Keywords : Water treatment techniques; Ozonation; Moving bed biofilm reactor; Trickling filter; Biological degradation; Lake Mälaren; attenreningstekniker; Ozonering; Biofilmreaktor med rörlig bädd; Biobädd; Biologisk nedbrytning; Mälaren;

    Abstract : Norrvatten produces and delivers drinking water to approximately 700 000 people in the northern part of the Stockholm region in Sweden. In their water treatment plant Görvälnverket, water from Lake Mälaren is purified. During the purification, sludge is produced. To be able to use the sludge as landfilling material, it must be dewatered. READ MORE

  5. 5. Analysis and modelling of ozone pre-treatment of sludge for biogas production

    University essay from KTH/Kemiteknik

    Author : Gokul Prasad; [2022]
    Keywords : Wastewater treatment; anaerobic digestion; sludge pre-treatment; ozonation; methane; Avloppsvattenrening; anaerob rötning; slamförbehandling; ozonering; metan;

    Abstract : Ozonförbehandling av avloppsvattenslam har diskuterats i litteraturen som en potentiell metod för att öka biogasproduktionen och minska slamvolymen. I detta arbete utvecklades en numerisk modell för att simulera effekten av ozonförbehandling på biogasproduktion genom anaerobrötning. Modellen bygger på en befintlig modell från litteraturen.
