Installation of the Hoot ANR Advanced Treatment Tank in Napa California

Hoot ANR for the Most Environmentally Sensitive areas in California

After 10 years of development and millions of dollars spent in research and 3rd party testing with NSF, The National Sanitation Foundation International.  Hoot proved what was previously discovered through research. Cost effective, efficient Nitrogen Reduction to below 10 mg/L can be achieved. 

The Hoot ANR (Advanced Nitrogen Reduction) is just one of a series of three treatment systems by Hoot that perform <10 CBODs & <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 for as possible (5.8 mg/L under the Standard 245).

The Hoot ANR-Series utilizes a “patent-pending” process that adds a food, carbon-based additive to provide the necessary off-gassing of Nitrogen as much as possible.  The entire additive dosing process is effectively managed by a computer controller that monitors system flow to ensure proportional dosing based on need and provides reliable Nitrogen Reduction performance for a range of TN influent strengths from 35-75 mg/L.

Our Hoot ANR-Series Treatment Systems are best suited for the most sensitive Environments with little or no organic content separation to the seasonal high water table or groundwater.  This level of performance provides the most nitrogen reduction per dollar, and ensures a healthy aquatic and drinking water environment, it is the only treatment system producing effluent that meets Federal Drinking Water Standards.
