The town of Boisbriand is located near the low Laurentians region, north of the Mille-Iles River. Its population in 2005 was 27 400 citizens. The Town of Boisbriand includes an important industrial concentration. For the last twenty years, the Town of Boisbriand has known an important demographic growth passing from 19,000 citizens in 1989 to 25,000 in 1996.

The town of Boisbriand has a "biological filtration" type waste water treatment plant which has been started-up in 1990. Following the town's important industrial, residential and commercial growth, the waste water treatment plant couldn't meet the environmental requirements for its wasted water anymore.

John Meunier Inc. suggested the installation of one (1) Actiflo^® clarification unit which has improved the treatment at the waste water treatment plant and more specifically has reduced the load admitted to the biological aerated filters (BAF).

The Actiflo^® clarifier was installed in 1998 as secondary treatment upstream the BAF. With this process, the existing BAF were able to meet the environmental requirements.

We also supplied the chemical titration systems and the process control system. John Meunier has realized the project's engineering, the treatment units manufacturing, piping and installation of this equipment.
