Center specialized in water technology

Cégep de Saint-Laurent


CTE's mission is to carry out applied research and development, technical assistance, and information dissemination activities in the field of water technologies. The Centre assists private companies, public and parapublic organizations in their development while enriching and supporting college-level teaching activities.

The CTE has a high level of expertise in the field of waters and is distinguished by its ability to scale-up water treatment processes and validate water treatment technologies. Our multidisciplinary team of engineers, chemists, microbiologists and technicians is an important asset in this field and allows us to respond well to problems. The centre also has the in-house capacity to manufacture pilot testing equipment and analyze various water quality parameters.
