  1. 1. Opportunities for increased nutrient recovery at centralised wastewater treatment plants through urine separation

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Hanna Gustavsson; [2021]
    Nyckelord :Nutrient recovery; urine separation; magnesium ammonium phospahte; MAP; ammonium sulphate; AMS; and DHI s WEST;

    Sammanfattning : Municipal wastewater contains a significant amount of nutrients such as phosphorus (P) and nitrogen (N). Therefore have the interest of recovering these nutrients at wastewater treatment plants (WWTP) increased. Nutrient recovery would generate revenue for the WWTP, as it is possible to sell the products as fertiliser. LÄS MER

  3. 2. Modelling the COD Reducing Treatment Processes at Sjölunda WWTP

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Tanya Klingstedt; [2015]
    Nyckelord :Technology and Engineering;

    Sammanfattning : The main focus of this thesis was to evaluate the possibility of establishing a wastewater treatment model for the main COD removal parts in the water line of Sjölunda Wastewater Treatment Plant (WWTP) located in Malmö, in southern Sweden. The finalised model was used to simulate an increased load of on average 5,000 population equivalents (P.E. LÄS MER

  4. 3. Investigation of soil related potential for sustainable growth and development of Oil Palm (Elaeis quineensis Jacq) in Nigeria

    Master-uppsats, SLU/Dept. of Soil and Environment

    Författare :Wisdom Ofremu; [2013]
    Nyckelord :Nigeria; oil palm; oil palm management; palm oil; soil properties; soil fertility; Nigerian Institute for Oil Palm and Research NIFOR ;

    Sammanfattning : Seven representative soil sites at the Nigerian Institute for Oil Palm and Research (NIFOR) were studied to evaluate the present fertility status of the soils for sustainable production of palm oil and in particular investigate the soil boron status. Profiles were sited at Edo State (Ed1, Ed2 and Ed3) and Akwa Ibom State (Akwa1, Akwa2, Akwa3 and Akwa4). LÄS MER

  5. 4. Batch flow behandling och kontinuerligt flöde av lakvatten i en rotzonsanläggning : En jämförande studie i pilotskala

    Kandidat-uppsats, Högskolan i Halmstad; Sektionen för ekonomi och teknik (SET)

    Författare :Dan Nilsson; [2010]
    Nyckelord :Constructed wetland; batch flow; landfill leachate; BOD; COD; total Kjeldahl nitrogen; TKN; Subsurface flow; SSF; Våtmark; rotzonsanläggning; lakvatten; batch; satsvis; BOD; COD; TKN; Kjeldahl kväve;

    Sammanfattning : This report deals with the performance of a batch flow treatment of landfillleachate compared with a continuous flow system. The parameters in focus were total Kjeldahl nitrogen (TKN), BOD5 and COD. The pilot-scale experiment used eight barrels with a volume of 150 liters. LÄS MER
