Another pioneering technology for Canada
The WaterNOx™ is an advanced nitrogen removal filter designed to service smaller flows with less maintenance and energy consumption than standard submerged filters with backwashing. The WaterNOx™ is a variant of the standard biological anoxic filtration denitrification system with external carbon addition for nitrified influent.
In new installations, the WaterNOx™ follows a nitrifying filter such as the Waterloo Biofilter. An inexpensive, easily digested carbon source is added to aid in the denitrification process. The WaterNOx™ effluent is then directed to a small polishing filter to remove excess organics before disposal.
In retrofit installations, the WaterNOx™ operates on a closed feedback loop receiving a portion of the effluent from the existing works, denitrifying it, and directing it back upstream to the septic tanks. The WaterNOx™ system also produces alkalinity that when directed back upstream further increases nitrification efficiency.
WaterNOx™ offers numerous advantages over
other nitrogen removal technologies
easy set-up and servicing
no aerobic sludge production
very low energy usage
permanent filter medium
safe, non-toxic carbon source
quick recovery if disturbed
