SBR remediation of monoethylamine under anoxic and oxic conditions

Ber-Lin Lai, University of Pennsylvania

Abstract

Monoethylamine (MEA) is the pollutant to be removed in this research. The postulate that ammonia will be generated when MEA is degraded in anoxic conditions led the research to study denitrification with MEA as the carbon substrate. As the postulate was proven to be true, it motivated the research to utilize sequencing batch reactors in remediation of MEA. Several batch denitrification experiments with different mineral solution recipes were performed with MEA as the only carbon source to find out the kinetic results and the influence of Mo, Cu, and yeast extract. Experimental data showed that MEA is biodegradable in anoxic conditions and ammonia is produced as one of the end products. The kinetic results appear to be zero order with respect to nitrate and carbon substrates for the different mineral solutions used, and Cu can enhance the anoxic degradation rate dramatically. Two sequencing batch reactors were used as the system in remediation of MEA. One was a suspended growth reactor and the other was a biofluidized bed reactor. The results showed sequencing batch reactors can effectively degrade MEA and the biofluidized bed reactor has better stability in treating high MEA loading.
