    Detta är en avhandling från Stockholm : Mark och vatten

    Författare :Jakob Ottosson; KTH.; [2003]
    Nyckelord :greywater; greywater reuse; greywater treatment; microbial risk assessment; groundwater recharge; irrigation; recreational water; faecal contamination; indicator bacteria; index organisms; faecal sterols; bacteriophages; enteric pathogens; rotavirus; ;

    Sammanfattning : Greywater is domestic household wastewater without inputfrom the toilet, i.e. wastewater from sinks, the shower,washing machine and dishwasher in a home. Source separation ofgreywater can be a strategy to enhance recirculation of plantnutrients and/or improve water use. LÄS MER

  2. 2. On-site sanitation systems - An integrated assessment of treatment efficiency and sustainability

    Detta är en avhandling från Luleå : Luleå University of Technology

    Författare :Brenda Vidal; Luleå tekniska universitet.; [2018]

    Sammanfattning : Water scarcity, inappropriate sanitation and wastewater pollution are critically important global issues. Greywater is a sustainable water source for recycling, so this thesis examined simple, robust, low-cost alternatives for on-site treatment of greywater to irrigation water quality. LÄS MER

  4. 4. Simulating water and pollutant transport in bark, charcoal and sand filters for greywater treatment

    Detta är en avhandling från Luleå : Luleå University of Technology

    Författare :Susanna Ciuk Karlsson; Sveriges lantbruksuniversitet.; [2015]

    Sammanfattning : A septic tank combined with a sand filter is the most common onsite wastewater treatment system worldwide, since it is a simple, lowcost and reliable treatment method. Alternatives to sand in filters could be advantageous in terms of availability of material and enhanced treatment properties. LÄS MER

  5. 5. Hazardous substances in wastewater management

    Detta är en avhandling från Luleå : Luleå tekniska universitet

    Författare :Helena Palmquist; [2004]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering;

    Sammanfattning : The extensive use of materials and substances in society causes diffuse source emissions that lead to uncontrolled spreading of hazardous substances, largely channelled via wastewater systems, to the surrounding nature. Complex mixtures of substances appear in wastewater as a result of use, wear, and corrosion of goods (e.g. LÄS MER
