   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Eco-technology; Carbon felts; PEDOT:PSS; Glucose oxidase immobilization; Cold remote plasma; Genipin.; 生态技术；碳毡； PEDOT:PSS；葡萄糖氧化酶固定化；低温等离子远程处理技 术；京尼平; Eco-technologie; nontissés de carbone; PEDOT: PSS; immobilisation de glucose oxydase; plasma froid; génipine; Ekoteknik; karbonfilt; PEDOT: PSS; immobilisering av glukosoxidas; kall fjärrplasma; genipin.; Textil och mode generell ; Textiles and Fashion General ;

   Abstract : Enzyme immobilization on electrically conductive supports is necessary to improve their bioactivity and stability, for use and re-use in applications depending on bio-electrochemical response, such as in bioelectrodes, biosensors, or biofuel cells. However, the immobilization methods used are still facing many challenges in terms of health hazards and high environmental impact. READ MORE

4. 2. Bed filters for phosphorus removal in on-site wastewater treatment : Removal mechanisms and sustainability

   Author : David Eveborn; Jon Petter Gustafsson; Gunno Renman; Erik Kärrman; Lars Lövgren; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; On-site wastewater treatment; Eutrophication; Environmental impact assessment; Phosphorus removal mechanisms; Soil infiltration; Reactive bed filters; Environmental engineering; Miljöteknik; Water engineering; Vattenteknik; Soil chemistry; Markkemi;

   Abstract : For many surface waters, phosphorus (P) leaching is a serious problem that should be minimized to prevent eutrophication. In Sweden there is a demand for physical and technical development of high-performance P removal techniques to reduce phosphorus leaching from on-site wastewater treatment systems to the Baltic Sea.

5. 3. Sustainable phosphorus removal in onsite wastewater treatment

   Author : David Eveborn; Jon Petter Gustafsson; Gunno Renman; Erik Kärrman; Paul Withers; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Onsite wastewater treatment; Soil treatment system; Phosphorus; Removal mechanisms; Environmental impacts; Life cycle assessment;

   Abstract : Aquatic eutrophication is a serious environmental problem that occurs all over the world. To protect surface waters (in particular the Baltic Sea), the regulatory pressure on onsite wastewater treatment (OWT) systems have increased in Sweden. READ MORE

6. 4. Development of a Low Cost Remediation Method for Heavy Metal Polluted Soil

   Author : Stalin Mkumbo; Gunno Renman; Ann-Margret Strömwall; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; autoclaved aerated concrete; decontamination; heavy metal; hyperaccumulator plants; sorbent; zeolite;

   Abstract : High concentrations of heavy metals in the soils have potential long-term environmental and health concerns because of their persistence and accumulation tendency in the environment and along the food chain. This study was aimed at studying the feasibility of heavy metals removal from the soil using plants naturally growing in the surroundings of selected polluted sites in Tanzania and soil application of the sorbent materials zeolite and autoclaved aerated concrete (AAC).

7. 5. Iron and aluminium speciation in Swedish freshwaters : Implications for geochemical modelling

   Author : Carin Sjöstedt; Jon Petter Gustafsson; Peggy O'Day; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Geochemical equilibrium modelling; pH; adsorption to ferrihydrite; metal-NOM complexation; liming; EXAFS spectroscopy;

   Abstract : Speciation governs transport and toxicity of trace metals and is important to monitor in natural waters. Geochemical models that predict speciation are valuable tools for monitoring. They can be used for risk assessments and future scenarios such as termination of liming. READ MORE
