Montreal Replaces Disinfection Systems

A local consortium comprised of Filtrum and Siemens will provide the design, supply, installation, commissioning, and training of the multi-million dollar OSEC systems, which mark the largest such installations in Canada. These systems will help the city comply with new stringent government regulations for drinking water quality.

Combined, the plants treat roughly 2.4 million m³ per day and serve approximately 1.6 million residents. These plant optimizations are part of a multi-billion dollar project that includes the update of all WTPs as well as the distribution system on the Island of Montreal.

Five OSEC B-Pak systems will be installed at the Des Baillets WTP for a capacity of 140 kg/hr (7,500 ppd); six others will be installed at the Atwater plant for a capacity of 168 kg/hr (9,000 ppd). The systems at the Des Baillets plant are expected to be operational next year; those at the Atwater plant, in 2012.
