  1. 1. A small scale wastewater treatment system adapted to nutrient recovery in cold climate : performance and possible sorbents

    Författare :Lea Rastas Amofah; Luleå tekniska universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering;

    Sammanfattning : Waterbodies are impaired by, among other things, discharge from onsite small- scale wastewater (WW) treatment systems. Hence, these systems need to be updated to improve the effluent quality and the reuse of nutrients within society. LÄS MER

  3. 2. An add-on filter technique to improve micropollutant removal and water quality in on-site sewage treatment facilities

    Författare :Wen Zhang; Gunno Renman; Erik Kärrman; Carlos Alberto Arias; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Micropollutant; on-site sewage facilities; physicochemical properties; pore structure; sorbents; surface functional group; Mark- och vattenteknik; Land and Water Resources Engineering;

    Sammanfattning : Onsite sewage treatment facilities (OSSFs) in Sweden currently release significant amounts of nitrogen (N) and phosphorus (P) into groundwater or/and receiving water bodies. Micropollutants (MPs) have been found in both surface water and groundwater, indicating insufficient removal of MPs by OSSFs. LÄS MER

  4. 3. Engineered Wetlands and Reactive Bed Filters for Treatment of Landfill Leachate

    Författare :Agnieszka Kietliñska; KTH; []
    Nyckelord :Blast furnace slag; Compact constructed wetland; Metals; Nitrogen; Polonite; Sorbents;

    Sammanfattning : The main objectives of this study were to investigate (i) anovel wetland treatment technology and (ii) selected bed filtermedia for the removal of contaminants from landfill leachate. Areview of the literature concerning experiences of the use ofconstructed wetlands (CW) for the removal of nitrogen fromlandfill leachate, showed that at least three groups oftreatment systems are in practice: sub-surface flow wetlands,hybrid systems (a combination of vertical and horizontal flowwetlands) and, compact constructed wetland (CCW).

  5. 4. Sustainable porous organic materials : Synthesis, sorption properties and characterization

    Författare :Fredrik Björnerbäck; Niklas Hedin; Knut Irgum; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; porous materials; sorbents; microporous; CO2 capture and separation; gas adsorption; activated carbon; humins; hypercrosslinked polymers; sustainable; materialkemi; Materials Chemistry;

    Sammanfattning : The resources available to us humans, including metals, minerals, biomass, air, water, and anything else on the planet, are being used at an increasing rate. This anthropogenic use of resources both depletes the resources and has negative impacts on other resources, e.g. the biosphere. LÄS MER

  7. 5. Titanium(IV) Phosphates : The Next Generation of Wastewater Sorbents

    Författare :Mylene Trublet; Oleg Antzutkin; Anna-Carin Larsson; Marina Maslova; Nigel Clayden; Luleå tekniska universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; Chemistry of Interfaces; Gränsytors kemi;

    Sammanfattning : Treatment of industrial waters containing heavy metal ions is essential before being discharged into the environment. Consequently, European regulations have been established to control and limit the amount of heavy metals released. LÄS MER
