    Changes in availability of Ca, K, Mg, P and S in sewage sludge as affected by pyrolysis temperature

  • Original language description

    In this study, anaerobically stabilised SS was pyrolysed in a laboratory fixed-bed reactor at 220, 320, 420, 520, and 620 C for 30 min in the N2 atmosphere. Pyrolysis resulted in a higher total content of all studied nutrients in BCs. Aromaticity and hydrophobicity of BCs increased with increasing temperatures while solubility decreased. Relative availability (% from total content) of nutrients in BCs decreased in order: Ca - Mg, K - S - P. Pyrolysis at 220 C produced acidic BC with a higher content of acetic acid-extractable nutrients compared to non-pyrolysed control. An increment in pH and a significant drop in the content of available Ca, Mg, K and S were found at temperature 320 C. Pyrolysis at 320 C increased the content of available P by 28 % compared to non-pyrolysed SS. At the temperature of 420 C and higher, available contents of all studied nutrients were lower than in non-pyrolysed SS.
