Preferred Treatment and Accepted Contaminants

Sanexen uses various MDDELCC recognized techniques, including biodegradation, soil vapour extraction or bioventing.


Biodegradation essentially consists of creating conditions favourable for the multiplication of microorganisms that allow for the degradation of hydrocarbons.

Soil Vapour Extraction consists of extracting VOCs by circulating air through the contaminated soils. The volatilized VOCs are collected and eliminated using specialized filters.

Bioventing consists of simultaneously or sequentially combining biodegradation and soil vapour extraction.
