  1. 1. Remediation of TNT-contaminated water by using industrial low-cost residue pine bark

    Author : Olga Chusova; Emma Nehrenheim; Monica Odlare; Jaquiline Akhavan; Mälardalens högskola; []
    Keywords : Energy- and Environmental Engineering; energi- och miljöteknik;

    Abstract : In the process of demilitarization of explosives, army ammunition plants generate a waste stream known as pink water. The principal component of the wastewater is the nitro-aromatic compound 2,4,6-trinitrotoluene (TNT). READ MORE

  2. 2. Environmental aspects of coal mine drainage: a regional study of Moatize in Mozambique

    Author : Estevao Pondja; Avdelningen för Teknisk vattenresurslära; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; coal mining; acid mine drainage; mine water treatment; climate change; low-cost adsorbent;

    Abstract : Mozambique is one of the largest coal producers in Africa. Extraction of the coal is carried out in the Moatize district of the Tete province in the center of the country. A surface mining technique is used to extract the coal below ground level. READ MORE

  3. 3. Tailoring residue-derived carbon materials for the removal of wastewater contaminants : adsorption and surface properties

    Author : Mirva Niinipuu; Stina Jansson; Jean-Francois Boily; Erik Rosenbaum; Magnus Bergknut; Capucine Dupont; Umeå universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Adsorption; hydrochar; HTC; chemical activation; wastewater; pharmaceuticals; metals; surface properties; biobased residues;

    Abstract : The availability of effective, low-cost wastewater treatment is necessary for increased water recycling and the prevention of environmental pollution on a global scale. Adsorption on activated carbons is commonly applied in wastewater treatment, but the high cost of conventional activated carbons limits the use of this technique. READ MORE

  4. 4. Modelling phosphorus dynamics in constructed wetlands upgraded with reactive filter media

    Author : Rajabu Hamisi; Gunno Renman; Berit Balfors; Roger Thunvik; Steve W. Lyon; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Constructed Wetland; COMSOL; Modelling; Reactive Solute Transport; Sorption Process; Mark- och vattenteknik; Land and Water Resources Engineering;

    Abstract : Developing low-cost and effective technologies to upgrade phosphorus (P) removal from the catchment runoffs and rural wastewater treatment facilities is one of the main research agendas to save the Baltic Sea from eutrophication. In Sweden, the construction of the constructed wetlands has been one of the environmental objectives for wastewater quality improvement in the small communities. READ MORE
