  2. 1. Ozone chemistry in aqueous solution : ozone decomposition and stabilisation

    Author : Margareta Eriksson; Lars Kloo; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Kemi; Chemistry; Kemi;

    Abstract : Ozone is used in many applications in the industry as an oxidising agent for example for bleaching and sterilisation. The decomposition of ozone in aqueous solutions is complex, and is affected by many properties such as, pH, temperature and substances present in the water. READ MORE

  4. 2. Simulation and Optimization of Recirculating Aquaculture Systems

    Author : Simon Pedersen; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; dynamic modelling; optimization; biofilter; wastewater treatment; Recirculating aquaculture;

    Abstract : Recirculating aquaculture -- intensive fish farming with water treatment and reuse -- has great potential as a method for sustainable food production. Benefits over traditional aquaculture include opportunities to reduce nitrogen emissions to water, control of temperature, salinity and pH, reduced environmental impact of escapes and better protection against e.

  5. 3. Off-flavours in drinking water : Analytical procedures and treatment effects in biologically active sand filters

    Author : Bo Lundgren; Linköpings universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Abstract : Taste and odour problems in drinking water are primarily caused by naturally produced, volatile, organic compounds. So far, research in this field has focused on a relatively small number of known compounds. READ MORE

  6. 4. Removal of organic micropollutantns from wastewater in a Swedish context

    Author : Maja Ekblad; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wastewater treament; ozone; ozonation; pharmaceutical residues; Organic micropollutants; driving forces; drivers; avloppsvattenrening; ozon; ozonering; läkemedelsrester; organiska mikroföroreningar; drivkrafter;

    Abstract : Due to their potential environmental risk, the abatement of organic micropollutants from wastewater has gained increasing attention in recent years. This thesis evaluates the use of ozone in Swedish wastewater treatment plants (WWTPs) and the incentives for full-scale implementation of organic micropollutant removal. READ MORE
