  1. 1. INVESTIGATION OF PHOSPHORUS SORPTION BY SEDIMENT DERIVED BIOCHAR - A LITERATURE REVIEW

    Master-uppsats, Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

    Författare :Christina Henricson; [2023]
    Nyckelord :;

    Sammanfattning : As excess phosphorus in water bodies causes eutrophication, biochar can be used as an adsorbent to remove phosphorus from water, thus increasing the circularity of phosphorus in the society. This literature review is a summary of recent research on optimised uptake of phosphorus by sediment derived biochar. LÄS MER

  3. 2. Phosphorus and Nitrogen Removalin Modified Biochar Filters

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för geovetenskaper

    Nyckelord :biochar; modified biochar; phosphorus filter; wastewater; batch adsorption experiment; nitrogen filter; COD; Tot-P; Tot-N; biokol; impregnerat biokol; fosforfilter; avloppsvatten; skakexperiment; kvävefilter; COD; Tot-P; Tot-N;

    Sammanfattning : Onsite wastewater treatment systems in Sweden are getting old and many of them lack sufficient phosphorus, nitrogen and organic carbon reduction. Biochar is a material that has been suggested as an alternative to the common sand or soil used in onsite wastewater treatment systems. LÄS MER

  4. 3. Tillsats av biokol till en svensk sandjord : effekter på lustgasavgång, kväveretention och andel vattenfyllda porer

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

    Författare :Rickard Almers; [2009]
    Nyckelord :lustgas; N2O; denitrifikation; biokol; träkol; svartkol; kväveretention; nitratretention; ammoniumretention; klimatförändringar; CO2; koldioxid; carbon capture and storage; CCS; kolsänka;

    Sammanfattning : In a column experiment the effect of three different biochars on nitrous gas emissions, nitrogenretention and water filled pore space (WFPS) were studied in a Swedish sandy soil, classified as aCryopsamment. Ammonium retention was positively correlated, while KCl-extractable ammoniumwas negatively correlated, with the specific area of the biochars. LÄS MER
