  1. 1. Reactive filter materials for ammonium and phosphorus sorption in small scale wastewater treatment

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

    Sammanfattning : Existing small scale wastewater treatment systems in Nordic countries have generally low treatment efficiency regarding phosphorus and nitrogen. Even though only 15% of the Swedish population is connected to on-site wastewater treatment systems, the total discharge of phosphorus from these systems exceeds the total discharge from all municipal treatment plants in Sweden.

  3. 2. 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 :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

  4. 3. Towards sustainability of environmental protection : recovery of nutrients from wastewater filtration and the washing of arsenic contaminated soils

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

    Sammanfattning : Conventional methods for wastewater treatment and remediation of the sites withcontaminated soils focus on protection of human health, receiving waters and theenvironment. Towards this end, these methods concentrate on the reduction or removal of polluting substances, and therefore, are not well suited for creating resources through the recovery of nutrients, energy and decontaminated soils.

  5. 4. Unlocking Sustainability in Wastewater Denitrification through Waste-Derived Volatile Fatty Acids

    Författare :Tugba Sapmaz; Mohammad J Taherzadeh; Eric D. Van Hullebusch; Högskolan i Borås; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; volatile fatty acids; wastewater denitrification; ammonium removal; sustainable carbon source; Resource Recovery; Resursåtervinning;

    Sammanfattning : Carbon sources play a critical role in biological nitrogen removal during wastewater treatment, where strict total nitrogen limits on effluent discharge apply. Organic carbon sources serve as electron donors in the denitrification for heterotrophic denitrifiers. LÄS MER

  7. 5. Investigation of nitrogen recovery from concentrated wastewater

    Författare :Aubrey Beckinghausen; Monica Odlare; Eva Thorin; Sebastian Schwede; Ershad Ullah Khan; Mälardalens universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nitrogen; ammonium; recovery; circular economy; wastewater; Energy- and Environmental Engineering; energi- och miljöteknik;

    Sammanfattning : Nitrogen recovery from wastewater treatment for fertilizers is a research topic that exists at the intersection of multiple topics important to the future of sustainable society. First, nitrogen recovery from wastewater implies a departure from the current methods of nitrogen mitigation, which involve nitrogen removal by conversion of various aqueous species to inert nitrogen gas.
