Nutrient pollution is a global environmental problem that has led to increasingly stricter regulations in wastewater treatment. As a result, many systems require upgrades. A comparative bench-scale and field site analysis of BioCord, a biotechnology that improves nutrient removal, was conducted to investigate seasonal microbial dynamics and its impact on nitrogen removal. This was assessed using metabolite (NO3-) stable isotope analysis, high-throughput sequencing of the 16S rRNA gene, and RT-qPCR of key genes in biological treatment representing nitrification, anammox, and denitrification. Bench-scale experiments using BioCord showed an increase in nitrifiers with increasing ammonia concentrations, resulting in an ammonia removal efficiency up to 98% in the BioCord system with only up to 25% observed in the control system. Compound specific stable isotope analysis showed that 15ε and δ18ONO3 could be used in monitoring the efficiency of the enhanced biological nitrification. In the lagoon field trials, an increase in nitrogen promoted three principle nitrifying genera (Nitrosomonas, Nitrospira, Candidatus Nitrotoga) and enhanced the expression of denitrification genes (nirK, norB, and nosZ). Further, anaerobic ammonia oxidizers were active within biofilm of BioCord. Even at lower temperatures (2 to 6 °C) the nitrifying bacteria were active on the BioCord. Future research should focus on using metatranscripotomics to identify syntrophic metabolic relationships in BioCord to better understand and predict treatment.
