This Small Business Innovation Research (SBIR) Phase II project will optimize and pilot test a novel, energy-positive approach to de-nitrification for the global aquaculture industry. Recirculating aquaculture systems suffer from high wastewater treatment costs. Leveraging recent advances in bio-electrochemical systems, Cambrian's de-nitrification technology is capable of simultaneously treating chemical oxygen demand (COD) at end of pipe and nitrates in culture tank water while generating electricity directly. Phase I R&D demonstrated the existence of exo-electrogenic microorganisms in aquaculture wastewater. A flow through reactor consistently treated nitrate to below EPA drinking water concentrations (10mg/L) while removing an average of 65% of end-of-pipe COD and generating over 96 Amps/m3. An economic analysis demonstrated potential operating savings of over 70%, and significant bio-security benefits, versus competing systems. Phase II R&D will focus on optimizing treatment rates and reactor parameters with partner firms, and piloting a scaled reactor at an Aquaculture farm.The broader impacts of this research are to introduce technologies and strategies that solve water and energy problems for the recirculating aquaculture industry. With the collapse of fisheries globally, the aquaculture industry is poised to fill an important gap in our food production. However, recirculating systems in particular are under pressure to limit environmental harm caused by water intensity and pollution. Bio-electrochemical systems represent a novel approach to turn waste resources into energy, thereby increasing farmer?s bottom line and resolving the tension between economics and sustainability. Future research can broaden applications to other industries.

这项小型企业创新研究（SBIR）第二阶段项目将优化和试点测试全球水产养殖行业的新型能量阳性方法。循环水产养殖系统遭受高废水处理费用。利用最新的生物电化学系统进步，寒武纪的硝化技术能够在培养坦克水中的管道和硝酸盐结束时同时处理化学氧需求（COD），同时直接发电。第一阶段的研发证明了在水产养殖废水中存在外电性微生物。通过反应堆的流量始终处理硝酸盐，至EPA饮用水浓度以下（10mg/L），同时平均消除了管状鳕鱼的65％，并产生超过96个AMP/M3。经济分析表明，与竞争系统相比，经营节省了70％以上，并且具有重大的生物安全收益。第二阶段的研发将集中于通过合作伙伴公司优化治疗率和反应堆参数，并在水产养殖场试行缩放反应堆。这项研究的更广泛的影响是引入技术和策略，以解决循环水产养殖行业的水和能源问题。随着全球渔业的崩溃，水产养殖业有望填补我们食品生产的重要空白。但是，循环系统尤其承受着限制水强度和污染造成的环境伤害的压力。生物电子化学系统代表了一种新颖的方法，可以将废物资源转化为能源，从而增加农民的底线并解决经济学与可持续性之间的张力。未来的研究可以扩大对其他行业的应用。
