The Concern over BNR
Biological Nutrient Removal (BNR) is expected to be the most significant challenge facing wastewater permittees for years to come.
Until now, compliance was a challenge made more difficult by the inherent deficiencies of the most widely used BNR processes, which are unable to quickly and cost-effectively meet increasingly stringent compliance mandates.
Fortunately, In-Pipe Technology® Company has a proven BNR approach that will help you meet new compliance standards quickly and cost-effectively.
In-Pipe Technology`s BNR Solutions
In-Pipe Technology enables you to achieve BNR by transforming your existing collection system into a vast, biological pre-treatment reactor. Through a patented sewer biofilm conversion process, In-Pipe Technology reduces the nitrogen and ortho-phosphorus concentrations entering your plant and breaks down difficult-to-degrade organics into readily biodegradable material for improved denitrification and/or phosphorus release in your BNR facility.
In addition, In-Pipe Technology significantly increases the quantity of facultative bacteria entering the treatment plant. These bacteria actually contribute to the BNR process, unlike strict anaerobes that dominate typical domestic wastewater.
Competitive Exclusion
The biological principle of “competitive exclusion`` is fundamental to the numerous, documented benefits of In-Pipe Technology. Beneficial bacteria are added continually, enabling them to outcompete the indigenous, damaging bacteria for available nutrients and food, ultimately dominating the wastewater and sewer biofilm.
The result is a stable, highly active, synergistic influent bacterial composition, as well as reduced nutrient loading and increased wastewater biodegradability. This combination is a perfect enhancement to any existing BNR process, improving performance and treatment plant capacity.
In-Pipe`s BNR Benefits
The benefits are proven and substantial
- Quick implementation and results
- Influent TKN load reduced by as much as 25%
- Nitrification improvement of up to 50% or more
- Year-round nitrification and denitrification, including cold water winter treatment
- Reduced or eliminated need for supplemental carbon addition
- FOG and odor control in your collection system and treatment plant
- No new capital expense and lower operating costs
By leveraging your existing plant and collection system infrastructure, and with reductions in operations and maintenance costs, In-Pipe Technology enables you to quickly achieve BNR, with significant improvement in less than three months.
The In-Pipe Technology Answer
Only with In-Pipe Technology can you meet BNR standards while you also eliminate odors, increase plant capacity, limit corrosion, control FOG and reduce sludge production, all at no additional cost.
