BlueNite® Biological Denitrification

BlueNite® is Nexom’s proven solution for reliable nitrate and total nitrogen removal. Using the Centra-flo® granular media filtration process, bacteria attached to the media convert nitrates into harmless nitrogen gas. The result: consistent effluent quality that meets even the most demanding regulations.

Key Benefits:

• Achieves nitrate levels below 1 mg/L NOx-N

• Handles fluctuating nitrate loads with ease

• Low capital and operational costs

• Modular design—available in free-standing tanks, skid mounts, or concrete cells

• Easily integrates with BluePRO® for phosphorus removal if needed later

How It Works:

1. A carbon source (like methanol, glycerin, or acetate) is added upstream.

2. Wastewater passes through continuous backwash, upflow sand filters.

3. Bacteria in the filter media convert nitrates into nitrogen gas.

4. Solids and excess biomass are removed, while clean media is recycled.

Why Choose BlueNite?

• Proven performance in meeting tough nitrate discharge limits

• Compact footprint, making it retrofit-friendly

• Low media replacement needs thanks to an advanced washbox design

• Designed for flexibility and future nutrient removal upgrades

With BlueNite®, your facility can meet today’s nitrogen limits and be ready for tomorrow’s stricter standards—without costly overhauls.
