  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. Reduktion av föroreningar i processvatten från en äggfabrik i Brasilien : Kväve- och fosforrening i anlagda våtmarker.

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

    Författare :Alexandra Charlson; [2014]
    Nyckelord :Constructed treatment wetland; nitrogen removal; phosphorus removal; industrial food wastewater; water purification; Anlagd våtmark; kväverening; fosforrening; processvatten från livsmedelsindustrier; vattenrening;

    Sammanfattning : A water treatment unit consisting of two aeration basins, two settling tanks, a residence basinand a horizontal subsurface flow wetland were used to treat wastewater from an eggprocessing factory in Brazil. The aim of this paper was to determine the efficiency of thesystem in reducing nitrogen, phosphorus, BOD5 and TSS (among other parameters) andgetting a further understanding on different kinds of constructed treatment wetlands as well astheir nitrogen and phosphorus removal processes.

  5. 4. An Investigation of RF Pollution Caused by IEEE 802.15.4 Body Area Networks

    Kandidat-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Författare :John Ako Enohnyaket; [2013]
    Nyckelord :RF Interference; IEEE 802.15.4; Body Area Networks;

    Sammanfattning : Advancement in wireless communication technologies such as wearable sensors together with recent developments in embedded computing area is enabling the design, development and implementation of body area networks. These network developments mainly use the IEEE 802.15.4 which is aimed at low power, short range communications. LÄS MER

  7. 5. 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
