Fast development of centralized agricultural biogas plants leads to high amounts digestate production. The treatment and disposal liquid fractions after on-site solid–liquid separation remains problematic due their organic, nutrient aromatic contents. This work aims study the variability remaining compounds in relation substrate origin, process parameters techniques. Twenty-nine digestates from...

man-made reservoirs constructed on running waters, where a decrease in flow velocity and anincrease in flocculent settling occurs, create perfect conditions for the deposition of allohtonic matter andadsorbed pollutants, such as toxic polychlorinated dibenzo-p-dioxins (pcdds) and polychlorinateddibenzofurans (pcdfs). the results obtained from the research on a cascade of five small reservoirs l...
