2. 1. 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.

4. 2. UV-based advanced oxidation process for nutrient stabilisation and organic micropollutant degradation in source-separated human urine

   Author : Natnael Demissie; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : Urine dehydration is one of the technological approach to recover nutrients in concentrated form from source separated urine. When drying fresh urine, nitrogen loss occurs due to hydrolysis of urea into ammonia unless methods to inactivate urease enzyme are employed. READ MORE

5. 3. Microbial communities in anammox and nitrifying biofilms

   Author : Carolina Suarez; Göteborgs universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; biofilms; AOB; partial nitritation anammox; nitrification; wastewater;

   Abstract : Excess of nitrogen in water bodies causes eutrophication. One important source of nitrogen is the effluent from wastewater treatment plants (WWTPs). Nitrogen in wastewater is most commonly removed by nitrification-denitrification. READ MORE

6. 4. STUDY OF BACTERIAL COMMUNITIES : – A WASTEWATER TREATMENT PERSPECTIVE

   Author : Adrian Rodriguez Caballero; Erik Dahlquist; Elzbieta Plaza; Mälardalens högskola; []
   Keywords : Activated sludge; COD removal; Constructed wetland; DGGE; FISH; Molecular microbiology; Nitrification; PCR; Wastewater treatment.; Energy- and Environmental Engineering; energi- och miljöteknik;

   Abstract : In this thesis, the application of molecular microbiology methods to understand wastewater treatment bio-reactions is described. Two different wastewater treatment systems were chosen for the experimental work. READ MORE

7. 5. Microbial Community Assembly during Aerobic Granulation

   Author : Raquel Liebana; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aerobic granular sludge; granulation; washout dynamics; membrane bioreactors; sequencing batch reactors; fluorescence in-situ hybridization; microbial community dynamics; reproducibility;

   Abstract : Environmental deterioration together with the increasingly restrictive legislation of water quality standards have led to a demand for compact, efficient and less energy consuming technologies for wastewater treatment. Aerobic granular membrane bioreactors (AGMBRs) combine the advantages of aerobic granular sludge and membrane filtration. READ MORE
