Bioreactor for groundwater treatment
Proponent:
Sanexen Environmental Services Inc.
Name of project :
Construction of a prototype using Ultrasorption with an absorbent bed bioreactor for groundwater treatment, two technologies developed with the Biotechnology Research Institute.
Summary description of project:
The project intends to field test a series of treatment processes circulating under a former waste burial site located alongside the St. Lawrence River. The treatment train consists primarily of three contaminant filter units:
- a mechanical filter unit to intercept the suspended particulates
- an Ultrasoption filter unit developed by Sanexen Inc. to capture the PCBs and oil residues
- a biofilter unit to break down the residual contaminants.
Despite highly fluctuating conditions in the parameters observed in the pumping site, the process has allowed eliminating 80% of the hydrocarbons and all the sulphur.
