  1. 1. Characterization and treatment of municipal landfill leachates

    Author : Ulrika Welander; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; physical chemical treatment; biological treatment; characterization; organic substances; leachate treatment; municipal landfill; Biotechnology; Bioteknik;

    Abstract : Abstract The efficiency of different leachate treatment methods for the removal of refractory organic compounds and ammonium-nitrogen was investigated. The methods evaluated were nitrification, denitrification, adsorption onto activated carbon, precipitation by ferric chloride or aluminum sulphate and oxidation by ozone or Fenton´s reagent.

  2. 2. Methodology for evaluation of hazards from solid waste and landfill-generated leachate

    Author : Britt-Marie Svensson; Lennart Mathiasson; Lennart Mårtensson; Ann-Sofi Rehnstam-Holm; Kenneth M. Persson; Högskolan Kristianstad; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Analytical protocol; organic pollutants; toxicity test; landfill leachate; leachate treatment; leaching test; waste acceptance criteria; Chemistry; Kemi; NATURAL SCIENCES; NATURVETENSKAP; leaching test; waste acceptance criteria.;

    Abstract : A methodology based on an analytical protocol for evaluation of hazards from landfill leachate and solid waste is described. A dynamic analytical protocol, the LAQUA protocol, including measurements of inorganic and water-quality parameters, polar and non-polar organic marker compounds, and toxicity, was constructed.

  3. 3. Development and Evaluation of a Filter-Bed-Based System for Full-Scale Treatment of Industrial Landfill Leachate

    Author : Pille Kängsepp; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; organic and inorganic pollutants; Landfill; shredder residue; vertical-flow filter bed; pond; leachate treatment; carbon-containing ash; peat;

    Abstract : It is well known that nature offers an abundance of materials and processes that can be adapted in low-tech fashion, to fabricate systems capable of removing pollutants from wastewater. During the last decade, extensive basic and engineering research on such natural treatment systems have led to improvement of the quality of discharged wastewaters. READ MORE

  4. 4. Industrial by-products in treatment of metals from polluted water

    Author : Emma Nehrenheim; Lars Wester; Björn Klöve; Mälardalens högskola; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; landfill leachate; water treatment; low cost sorbent; pine bark; field study; batch experiments; Environmental engineering; Miljöteknik;

    Abstract : Water treatment can be carried out effectively by passive, low cost methods, as an addition or alternative to existing advanced technology. Energy and resource use can be optimized (i.e. minimized) by reusing by-products from local or regional manufacturing of timber and steel. READ MORE

  5. 5. Role of soil organic matter for immobilisation of metals : treatment of leachate from MSWI bottom ashes

    Author : Jurate Kumpiene; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Waste Science and Technology; Avfallsteknik;

    Abstract : In this thesis, the focus is laid on the ability of natural organic matter (OM) to serve as a metal stabilising agent. The metal contaminants investigated arise from the MSWI bottom ash leachate. Besides the high content of metals, elevated pH and salinity are characteristic for ash leachate that, in turn, can alter the functionality of OM. READ MORE
