  1. 1. Treatment of domestic wastewater using microbiological processes and hydroponics in Sweden

    Författare :Anna Norström; Gunnel Dalhammar; Jörgen Hanaeus; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Microbiology; biological; hydroponics; microbial composition; nitrogen; organic matter; phosphorus; small scale; theoretical energy requirements; wastewater treatment.; Mikrobiologi; Microbiology; Mikrobiologi;

    Sammanfattning : Conventional end-of-pipe solutions for wastewater treatment have been criticized from a sustainable view-point, in particular regarding recycling of nutrients. The integration of hydroponic cultivation into a wastewater treatment system has been proposed as an ecological alternative, where nutrients can be removed from the wastewater through plant uptake; however, cultivation of plants in a temperate climate, such as Sweden, implies that additional energy is needed during the colder and darker period.

  4. 3. Coagulant Protein from plant materials: Potential Water Treatment Agent

    Författare :Ida Bodlund; Gunaratna Kuttuva Rajarao; Anna Norström; Andres Veide; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; antimicrobial effect; Brassica; coagulant protein; MO2.1; Moringa oleifera; Mustard; napin; thermo-resistance; plant material; protein extraction; salt extract.;

    Sammanfattning : Access to fresh water is a human right, yet more than 780 million people, especially in rural areas, rely on unimproved sources and the need for finding ways of treating water is crucial. Although the use of natural coagulant protein in drinking water treatment has been discussed for a long time, the method is still not in practice, probably due to availability of material and limited knowledge.
