  1. 21. ARSENIC REMOVAL BY PHYTOFILTRATION AND SILICON TREATMENT : A POTENTIAL SOLUTION FOR LOWERING ARSENIC CONCENTRATIONS IN FOOD CROPS

    Författare :Arifin Sandhi; Gunnar Jacks; Gunno Renman; Maria Greger; Roger Herbert; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; aquatic moss; grain; rice; lettuce; macrophyte; phytoremediation; speciation; temperature; oxygenation; wetland.; Land and Water Resources Engineering; Mark- och vattenteknik;

    Sammanfattning : Use of arsenic-rich groundwater for crop irrigation can increase the arsenic (As) content in food crops and act as a carcinogen, compromising human health. Using aquatic plant based phytofiltration is a potential eco-technique for removing arsenic from water. LÄS MER

  3. 22. An add-on filter technique to improve micropollutant removal and water quality in on-site sewage treatment facilities

    Författare :Wen Zhang; Gunno Renman; Erik Kärrman; Carlos Alberto Arias; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Micropollutant; on-site sewage facilities; physicochemical properties; pore structure; sorbents; surface functional group; Mark- och vattenteknik; Land and Water Resources Engineering;

    Sammanfattning : Onsite sewage treatment facilities (OSSFs) in Sweden currently release significant amounts of nitrogen (N) and phosphorus (P) into groundwater or/and receiving water bodies. Micropollutants (MPs) have been found in both surface water and groundwater, indicating insufficient removal of MPs by OSSFs. LÄS MER

  4. 23. Enhanced phosphorus removal from wastewater using virgin and modified slags : performance, speciation and mechanisms

    Författare :Minyu Zuo; Gunno Renman; Jon Petter Gustafsson; Lars Lövgren; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; AOD; EAF; BFS; Calcium phosphate; XANES; slag mineralogy; Mark- och vattenteknik; Land and Water Resources Engineering;

    Sammanfattning : Argon oxygen decarburization slag (AOD) was tested in batch and column experiments to investigate its phosphorus (P) removal performance. The effects of factors such as AOD dose, initial P concentration of the feeding solution, and aging on the P removal ability of the slags were analyzed. LÄS MER
