NX Filtration Supplies Membrane Treatment for Canadian Drinking Water

Drinking water utilities increasingly face source water variability that can reduce treatment stability, particularly when surface water contains elevated organic matter and poor UV transmittance. In this context, NX Filtration was selected to supply its hollow fiber nanofiltration (HFNF) technology for a new Canadian drinking water treatment project being delivered by Komline Pure Water for the Ministry of Environment and Parks, with McElhanney serving as Engineer of Record.

The system is designed to treat a surface water source with fluctuating quality characteristics that limit the performance of conventional treatment approaches.

Addressing unstable surface water quality
The source water for the project is characterized by elevated natural organic matter (NOM), color, and low UV transmittance. These conditions can interfere with downstream disinfection processes and create operational variability in drinking water treatment plants.

High NOM concentrations are particularly relevant because they can increase disinfectant demand and complicate removal of dissolved contaminants, while low UV transmittance reduces the effectiveness of ultraviolet disinfection systems.

For utilities managing variable raw water sources, treatment systems must maintain stable performance despite seasonal or environmental shifts in water composition.

Membrane filtration as a treatment barrier
NX Filtration’s HFNF technology was selected as the primary treatment approach for the project. Hollow fiber nanofiltration systems use membrane separation to remove dissolved organic compounds, micropollutants, and other fine contaminants that conventional treatment processes may address through multiple sequential stages.

By reducing the concentration of organics before final disinfection, the system is intended to improve downstream treatment efficiency and support more consistent drinking water quality.

Compared with conventional multi-stage treatment trains, membrane-based water treatment can reduce process complexity where source water variability is a primary design challenge.

Canadian deployment partners
Komline Pure Water is delivering the treatment project as the Canadian industrial water and wastewater treatment contractor, while McElhanney is serving as Engineer of Record.

The deployment reflects broader adoption of advanced membrane technologies in municipal water treatment, particularly where conventional clarification and disinfection processes face performance constraints due to increasingly complex source water conditions.
