Saint-Hyacinthe, Qc, Canada
Mandate execution period :
First phase : 2009 – 2010
For these two phases, Génitique was awarded a contract to provide complete engineering services to lay out, build and commission the biomethanation process.
The Saint-Hyacinthe wastewater treatment plant was commissioned in 1987. The biological process to treat the urban and industrial wastewater produces organic sludge continuously. Since a few years, this sludge has been a serious problem given the continually increasing cost for transportation and disposal.
Since the city managers wanted to find a permanent and environmentally friendly solution, in the first phase they decided to install three (3) anaerobic digesters connected to the municipal sludge treatment system and to a dryer system.
In the second phase, the city of Saint-Hyacinthe adds the processing of organic materials from the agri-food industry and the collection of residential organic waste which requires the addition of 5 digesters, 2 hydrolysers, whey tank and 3 tanks of liquid organic materials.
