  2. 1. Evaluation of Biological Biomaterial Properties using Microfluidic Systems

    Author : Abdul Raouf Atif; Gemma Mestres; Séverine Le Gac; Uppsala universitet; []
    Keywords : Bone; Flow; Hydroxyapatite; In vitro; Modelling; On-chip; PDMS; Teknisk fysik med inriktning mot mikrosystemteknik; Engineering Science with specialization in Microsystems Technology;

    Abstract : Despite increased orthopedic biomaterial research activity over previous decades, relatively few novel biomaterials have made it to clinical use. This may partially be due to the inability of existing in vitro testing routines to sufficiently replicate the physiological environment, leading to potentially inaccurate assessments of a biomaterial’s therapeutic potential.

  4. 2. The influence of soil and contaminant properties on the efficiency of physical and chemical soil remediation methods

    Author : Sofia Jonsson; Mats Tysklind; Peter Haglund; Staffan Lundstedt; Tuula Tuhkanen; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fenton’s reagent; ozone; solvent washing; granular activated carbon; GAC; Persistent organic compounds; Persistenta organiska föreningar; Cardiology; kardiologi;

    Abstract :  A vast number of sites that have been contaminated by industrial activities have been identified worldwide. Many such sites now pose serious risks to humans and the environment. Given the large number of contaminated sites there is a great need for efficient, cost-effective  remediation methods. READ MORE

  5. 3. Adsorption and transformation of organic micropollutants in wastewater : New insights from 14C-labeling

    Author : Alexander Betsholtz; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; activated carbon; ozonation; Organic micropollutants; pharmaceuticals; wastewater; transformation products; biological degradation; GAC-filters; adsorption; 14C-labeling;

    Abstract : This thesis focuses on the removal of organic micropollutants and transformation products using ozone and activated carbon treatment processes. A combination of 14C-labeled and non-radiolabeled organic micropollutants was used to study aspects of micropollutant removal from novel perspectives. READ MORE

  6. 4. Pharmaceutical compounds; a new challenge for wastewater treatment plants

    Author : Maja Dlugolecka; Elzbieta Plaza; Bengt Hultman; Nicklas Paxéus; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; activated sludge; biodegradation; granular activated carbon GAC ; membrane bioreactor MBR ; pharmaceutical compounds; wastewater; Water engineering; Vattenteknik;

    Abstract : Analytical analyses conducted at the Himmerfjärden WWTP (285.000 PE connected) identified 70 pharmaceutical compounds belonging to different therapeutic classes. Such organic micropollutants at low detected concentration range of µg - ng l-1 did not affect the treatment processes at WWTP. READ MORE

  7. 5. Exploring the role of granular activated carbon in drinking water production

    Author : Malin Ullberg; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Safe and clean drinking water is recognised as a human right by the United Nations, but water sources world-wide are affected by the widespread use of synthetic chemicals, creating a challenge that drinking water producers must address. Many of these synthetic chemicals, here referred to as organic micropollutants (OMPs), are not well removed by conventional drinking water treatment, and thus additional treatment steps are needed.
