Total Nitrogen Below 10 mg/L, No Matter the Influent Strength? Now that the manufacturing community has begun to embrace On-Site Nitrogen Reduction, Hoot would like to educate you on what they have done. In 1999, Hoot began their Nitrogen Reduction work in response to regulatory concerns they identified in Florida. There was a “Key’s Standard” that was being largely ignored. Since then, no less than 10 companies have tried to enter that market, some with as few as 6 samples to “Justify” system performance to below 10 mg/L TN, the level determined necessary to protect the critical springs area’s. Initial research at Baylor University focused on utilizing 4 different configurations of Hoot systems. Certified to NSF/ANSI Standard 245 In 2006, Hoot began 3rd Party NSF testing to “Prove” what was previously discovered through research. Cost effective, efficient Nitrogen Reduction to below 10 mg/L can be achieved. As result the first (and only) system certified below 10 mg/L was born. The Hoot-ANR is just one of a series of three treatment systems by Hoot that perform <10 CBOD5 & <10 TSS at the lab and in the field. Additionally, Hoot offers two Nitrogen Reduction Technologies; one utilizing timed recirculation and another that achieves the maximum Nitrogen Reduction, for the most sensitive environments, that reduces Total Nitrogen as far as possible (5.8 mg/L under the Standard 245). The Hoot-ANR utilizes a “patent pending” process that adds a food grade additive to provide additional carbon necessary to off gas as much Nitrogen as possible. This process is controlled by a controller, not homeowners. By monitoring flow through the system, it ensures flow proportional dosing to provide reliable performance. Additional set points can be selected by the maintenance provider for a range of influent from of 35 to 75 mg/L TN. Some recently advertised studies, NOT certifications, have allowed for system performance to be ignored for the first 16 weeks of the study. The NSF Standard 245 allows a maximum of only a 3 week startup. At the end of week 4, the Hoot-ANR achieved a 92% reduction. (2.7 mg/L TN) When the environment demands this level of treatment and performance, Think Hoot. If your area needs this level of performance now, Hoot is looking for local precasters to cover the entire country. Hoot has spent the last 6 years and millions of dollars in Research & Development working to get Total Nitrogen below 10 mg/L. During this time the Nitrogen issue has been marginalized and regarded by some of the competition as “less important than making sure a riser is screwed down.” Hoot set out to prove that cost effective Nitrogen Reduction could be achieved, and the technology made available at a price that people could afford.
