  2. 11. Biological Treatment of Oily Sludge and Sediments

    Author : Mait Kriipsalu; Chalmers tekniska högskola; []
    Keywords : bioremediation; refinery; aerobic biotreatment; flocculation-flotation unit FFU ; petroleum hydrocarbons; oily sludge; static biopile; PAHs; sediments;

    Abstract : AbstractOily sludge, generated in refineries or in other industrial sectors, and oil-containing sediments, removed from water bodies during remediation works, pose an environmental problem. A common feature between both is their high water content, and variable content of organic and inorganic contaminants, which complicates their treatment. READ MORE
