Abstract

Composting is being widely employed in the treatment of petroleum waste. The purpose of this study was to find the optimum control parameters for petroleum waste in-vessel composting. Various physical and chemical parameters were monitored to evaluate their influence on the microbial communities present in composting. The CO₂ evolution and the number of microorganisms were measured as the activity of composting. The results demonstrated that the optimum temperature, pH and moisture content were 56.5 - 59.5°C, 7.0 - 8.5 and 55% - 60%, respectively. Under the optimum conditions, the removal efficiency of petroleum hydrocarbon reached 83. 29% after 30 days composting. Copyright © 2001 IOS Press.
