Study of biological parameters during composting of sewage sludge

The development of appropriate strategies for the treatment and disposal of sewage sludge is a major problem for all countries throughout the World. Sludge treatment and disposal not only represents about half of the total costs of municipal wastewater collection, but it is also strongly regulated,...

Hence sawdust was homogenized with the sludge to increase the C/N ratio of the sludge, which inoculated with a mixture of P.chrysosporium and Trichoderima harzinum. This also reduced the moisture content to the optimal level for composting. In a medium scale horizontal drum bioreactor occurred for 21 days and one month curing, the biological parameters were monitored to evaluate the effect of sawdust on the composting process.
