AUTOMATED, ONLINE NITROGEN ANALYZER

The overall objective for this Phase II SBIR project is to build an accurate, repeatable prototype analyzer for hydroxylamine and ammonia in wastewater treatment samples. This system will be tested by partners at trial sites in the San Francisco Bay Area.The first goal is to build and operate an automated system capable of simultaneous ammonia and hydroxylamine analysis using real-world samples. These samples will be obtained from our project partners. Our goal will combine the systems and knowledge gained during the Phase I efforts into a prototype system for internal development and experimentation on real-world samples. The primary goal is to perform autonomous ammonia and hydroxylamine analysis at a 5-ppb LOD in real-world samples containing 1-ppm ammonia with a standard error on the mean of 20% over a one-week period with hourly testing in real-world wastewater samples.The second goal will address reagent limitations, with increased manufacturing capacity. Our reagents require improved packaging that can be delivered and installed in the field. By addressing manufacturing concerns before producing a commercial prototype, we can identify potential limitations before field trials start.A first prototype will be installed at a wastewater treatment plant. The goal is to measure ammonia and hydroxylamine each with 20% error (defined as standard deviation on the mean).The second prototype system will be delivered to a wastewater treatment plant. The objective is to measure ammonia and hydroxylamine each with 20% error.These four goals will provide OndaVia with the data needed for product commercialization in Phase III.
