Biological Nutrient Removal (BNR) is expected to be the most significant challenge facing wastewater permittees for years to come. 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.
