Evaluation of nitrogen removal methods in seawater using novel polymeric materials

Abstract

The environmental impact of discharging large volumes of seawater containing high concentrations of nitrogen components is becoming increasingly problematic. An evaluation test was conducted on the removal ability of nitrogen components contributed by Rice Wave, a newly developed and manufactured polymeric material. As a result, although the adsorption capacity of nitrogen component ions was not observed, it was found that the removal capacity (biodegradation) was almost the same as that of conventional filter media when marine bacteria were administered, indicating that it can be used as a replacement for existing filter media. And the performance of denitrification was not sufficient, suggesting that measures such as pH control and increasing the density of added denitrifying bacteria are necessary.
