Denitrification Method Using Microorganisms Entrapped in PEG in Aerobic Waters (The consideration on the operating conditions)

Abstract

To plan a apparatus using microorganisms entrapped in PEG for removal of nitrogenic compounds, the effect of operating conditions for denitrification was examined. As operating conditions, flow rate, and operating mode (continuous or un-continuous operation) were determined. The most suitable condition of flow rate, ON-time and OFF-time of un-continuous mode were found. And it became clear that un-continuous mode has twice ability of denitrification than continuous mode, based on supplied energy.
