Influence of bulking agent on sewage sludge composting process
Four types of compost, consisting of mixtures of Acacia dealbata (A) with sewage sludge (SS) were studied in a laboratory reactor. Composting time was 80 days and parameters monitored over this period included temperature, organic matter, pH, CO 2, O 2, C/N ratio, Kjeldahl-N, as well as maturity ind...

| description | Four types of compost, consisting of mixtures of
Acacia dealbata (A) with sewage sludge (SS) were studied in a laboratory reactor. Composting time was 80
days and parameters monitored over this period included temperature, organic matter, pH, CO
2, O
2, C/N ratio, Kjeldahl-N, as well as maturity indexes. All the studied parameters were influenced by the bulking amount used. The highest profile temperature measured was for the A/SS 1/2 (w/w) mixture that reached a maxima temperature of 67
°C and lower maximum temperatures of 52, 48 and 46
°C were observed for A/SS 1/3, 1/1 and 1/0 composts, respectively. The kinetic model used showed that a descent of sewage sludge in the composting mixtures favored the enzyme–substrate affinity. However, an increase in depending on the parameters of the process factors was observed when the sewage sludge ratio was increased in mixtures. The optimal amounts of sewage sludge for co-composting with Acacia indicate that moderate amounts of sludge (1/1) would be the best compromise. |
