2. 1. Sustainable Development: Implementation in Urban Water Systems

   Author : Ali Bagheri; Avdelningen för Teknisk vattenresurslära; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Miljöteknik; pollution control; Environmental technology; Naturvetenskap; Natural science; Water resources systems; Viability loops; Urban water system; System dynamics; Sustainable development; Strategy; Social learning; Process; Principles; Indicators; Planning; Monitoring; kontroll av utsläpp;

   Abstract : As Sustainable development, a widely used but poorly understood term, challenges traditional scientific values such as prediction and control, scientists have tried to manipulate the concept to promote their own particular agendas. Thus, it has suffered from misrepresentation which has prevented the concept from being fully implemented at a practical level. READ MORE

4. 2. Realising full-scale control in wastewater treatment systems using in situ nutrient sensors

   Author : Pernille Ingildsen; Industriell elektroteknik och automation; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reglerteknik; robotteknik; Automatiska system; control engineering; Instrumentation; Wastewater treatment; Control; Full-scale plants; Control structures; Electronics and Electrical technology; Elektronik och elektroteknik; robotics; Automation; kontroll av utsläpp; pollution control; Miljöteknik; Environmental technology;

   Abstract : Abstract A major change in paradigm is taking place in the operation of wastewater treatment plants as automatic process control is becoming feasible. This change is due to a number of different reasons, not least the development of online nutrient sensors, which measure the key parameters in the biological nutrient removal processes, i.e. READ MORE

5. 3. Urban wastewater systems: From disposal to reuse. A study of different systems with focus on water and nutrients flows

   Author : Justyna Czemiel Berndtsson; Avdelningen för Teknisk vattenresurslära; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Storm Water; Urban; Wastewater; Civil engineering; offshore technology; hydraulic engineering; Väg- och vattenbyggnadsteknik; soil mechanics; pollution control; Environmental technology; Miljöteknik; kontroll av utsläpp; Nutrients;

   Abstract : Urban wastewater systems are currently exposed to a major rethink dictated by new demands on resource management. It is postulated that next to providing efficient sanitation (preventing spread of pathogenic microorganisms) these systems should support resource reuse. READ MORE

6. 4. Dynamics of water pollution control : A regional evaluation

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

   Abstract : The 1970's saw a strong governmental backing of measures taken to improve surface water quality by reducing point-source emissions in Sweden. The aim of this thesis primarily was to evaluate the cost effectiveness of governmental strategies implemented to improve surface water quality and to study the relationship between policies adopted and current knowledge about different sources of pollution.

7. 5. Mitigating Microplastics Pollution in Urban Water Systems : Flow, actors, and control measures

   Author : Emma Fältström; Stefan Anderberg; Annica Carlsson; Hamse Kjerstadius; Lian Lundy; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Municipalities; Plastic; Pollutants; Preventive measures; Stormwater; Wastewater; Water treatment;

   Abstract : Water pollution has long been considered a challenge in urban areas. Urban wastewater and stormwater act as transport pathways for pollutants from urban areas to receiving waters. Microplastics are a pollution problem of growing concern. READ MORE
