 Background
The objective of this project is to treat 21,600 tons of oily
waste from a 4,560 m2 retention pond. The waste consists mainly of
tank bottom residue, wastewater treatment sludge (biological sludge
and froth), contaminated soil from accidental spills, as well as
debris (metal, plastic and wood). This waste is highly contaminated,
reaching up to
420,000 ppm of total petroleum hydrocarbons, 3,160
ppm of monocyclic aromatic hydrocarbons and 5,120 ppm of polycyclic
aromatic hydrocarbons.
Solution
Following an evaluation of thermal, physical (centrifugation,
solidification) and biological solutions, Biogenie proposed a fixed-price remedial solution based on the on-site biological
treatment of the waste, followed by disposal of the treated material
in a sanitary landfill. The selected solution has proven to be the
most economical and provides substantial cost savings when compared
to the more traditional solution of disposal in a security landfill.
Following removal from the pond, nutriments and a bulking agent will
be added to the contaminated material that will then be treated
utilizing an ex situ Biopile process. The resulting material will be
non-hazardous, as such, can then be disposed of in a sanitary
landfill. Overall, 21,600 tons of highly contaminated material,
ranging in consistency from liquid to solid, will be treated in five
consecutive batches over the course of five years.
Services
-
Characterization of the retention pond and contaminated material;
- 3D
visualization of the contaminated material in the pond, allowing
for a more accurate estimate of the total volume;
-
Feasibility study to evaluate various treatment options, including
a treatability study to confirm the viability of a biological
treatment solution;
-
Securing all required permits and design of a site-specific Health
and Safety Program;
-
Environmental impact assessment of the proposed remedial solution;
-
Community outreach: presentation of the remedial solution at
public hearings.
