Soil Bioremediation using BTX
BTX is a blend of microbes that can be immobilised in Biochar for the bioremediation of petroleum hydrocarbon pollutants
Total Petroleum Hydrocarbon, TPH concentration can be quantitatively assessed using standard USEPA method 8015c
TPH and BTEX decrease is used as evidence of biodegradation
Proven in the field for the bioremediation of phenol, oil and sludge contaminated soil and GW
Eco-friendly compared to incineration or landfill
Cost effective with low carbon footprint
Before and during bioremediation
Figure 1.
The first photo shows the Ex-Situ Bio-pile bioreactor within the petrochemical facility where the oil and sludge contaminated soil was first unloaded into the oil and grease pit which was modified into a bioreactor pit, a bio-pile.
The second photo shows how a tarp was constructed over the bioreactor pit to prevent flooding and wash-out.
TPH analysis before and after soil bioremediation

After soil bioremediation without addition of fertilisers
Figure 3.
A photo of the actual site where the oil and sludge contaminated soil was stored prior to use for landscaping after bioremediation. No fertilisers or seeds were used.
