“…Wśród stosowanych i badanych metod dezintegracji wykorzystuje się głównie: ozonowanie [3], alkalizowanie [10], zakwaszanie [24], użycie wysokiego ciśnienia [8], rozdrabnianie mechaniczne [16], enzymy [21], ultradźwięki [25], promieniowanie mikrofalowe [6] oraz zamrażanie/ rozmrażanie [15,19].…”

“…Gao (2011) found a 2 to 8 fold increase in soluble chemical oxygen demand (SCOD) and NH 3 concentrations after F/T conditioning of WAS while Montusiewicz et al (2010) found a 2 fold increase in SCOD after F/T conditioning of a 1:4 mixture of primary and secondary sludge. Septage, with a typical sludge age of 2 to 5 years, has already undergone significant stabilization and should contain more humus and less biologically active material compared with other biological sludges and therefore should not encounter the same increase in SCOD and NH 3 concentrations.…”

“…In spite of high dewatering potentials, these methods have limited applicability due to its high operational cost and energy consumption factors and possess complexity of implementation. Besides these operational issues, pretreatment approaches involve the high risk in organic matter content loss in dewatered sludge cakes and also produce highly organic and ammonia loaded wastewater, which is difficult to treat (Neyens and Baeyens, 2003;Montusiewicz et al, 2010). Sludge generated by the CEPT process is usually treated with polyelectrolytes.…”
