Produksi gas karbon dioksida selama proses bioremediasi limbah heavy oil dengan teknik landfarming

Abstract

Bioremediation is defined as biological degradation process of organic or inorganic wastes in a controlled condition to control and reduce their amount in the environment. In this study, the soil which had been poluted by heavy petroleum oil fractions, i.e. heavy oil waste (HOW), was used as sample. The bioremediation technique used in this study is an ex-situ technique. This study was conducted to determine the amount of produced CO2 gas during the HOW degaradation process. Treatment of heavy oil waste with biostimulation and bioaugmentation. Production of CO2 gas were placed in impiger and analysis with titrimetry method. The highest CO2 production mean was obtained from the bioaugmentation treatment with compost adding, i.e. 244,5 mg/m3. Generally, graphs CO2 gas production followed a similar sinusoidal pattern. From these results it can be infered that the degradation process of HOW happened during the treatments in aerobic condition.
