sludge composting - principle and conditions governing its use

Composting is controlled fermentation that converts organic matter aerobically and produces stable humic and pre-humic compounds (figure 1). Aeration will only be effective if the medium is air-permeable. Dewatered sludge often has a low porosity; a bulking agent has to be added, usually in the form of a carbonaceous support (20% of the mixture
