Whether caused by nutrient-rich industrial processes, mining activity or aquaculture discharge, nitrate in wastewater can quickly become a limiting factor – overwhelming denitrification capacity, threatening compliance, driving up nitrate water treatment costs, or preventing efficient water recycling.
With the right nitrate removal system, you can:
The right solution doesn’t just meet standards. It improves operational efficiency, reduces waste, and makes nitrate compliance simpler to sustain.
Don’t settle for compliance. Demand performance – no matter the load.
Traditional nitrate removal plants use bacteria to break down nitrates in waste waters, which are often not able to meet the strictest (<5 ppm) nitrate effluent concentrations required for disposal of water into sensitive environments such as rivers, lakes and drinking water catchments. This challenge is even greater during colder weather months when bacteria are less active.
Our BIOCLENS® lenses contain encapsulated, living bacteria in a stable, porous PVA gel matrix. The bacteria are specifically selected for denitrification in fresh and seawater conditions, where nitrate / nitrite are converted into harmless nitrogen gas.
BIONEX™ is well suited for polishing nitrate to <1 ppm for large flowrates of water (>1 MLD). Ion exchange resin is used as the primary treatment method to efficiently remove nitrate to low levels in all conditions. BIOCLENS® are then used on the concentrated nitrate stream to remove the nitrate, allowing the waste brine to be reused to regenerate the ion exchange resin. This greatly reduces the chemical consumption, waste production, and operating cost of the plant.
