 Background
The objective of this project is to demonstrate the feasibility
of treating highly contaminated refinery waste by applying
a biological solution. Typically, this refinery produces annually
1,200 m3 of API separator sludge and biological
sludge produced by the wastewater treatment plant. The maximum level
of contamination for the first can reach as much as 500,000 ppm
of TPH and for the latter, 300,000 ppm of TPH. In Phase 1,
by attaining a 90% treatment efficiency, Biogenie clearly demonstrated
the feasibility of a biological solution. Following further optimization
of the treatment parameters, Phase 2, launched in September
2000, has as an objective that of achieving an even greater treatment
efficiency. Results achieved in Phase 1 clearly testify to the fact
that not only is Biogenie’s solution feasible, but in addition,
it provides 60% cost savings when compared to the more traditional
solution of stabilization followed by disposal in a security landfill.
Solution
Following removal from the pond, nutriments and a bulking agent
were added to the contaminated material prior to being treated utilizing
an ex situ Biopile process so as to obtain a non-hazardous
material, which can then be disposed of in a sanitary landfill.
This project is being implemented on a permanent treatment facility
designed, built and operated by Biogenie on the premises of the
refinery.
Services
- Characterization
of the contaminated material;
- Feasibility
study to evaluate the viability of a biological treatment solution;
- Phase
1 addressed the treatment of 60 tons of highly contaminated
material by means of a biological solution;
- Phase
2, which is ongoing, involves the application of the aforementioned
process to 100 tons of the same type of material.
