제목 Precipitation of struvite by utilization of ammonium ions in flue gas scrubbing wastewater
초록 Struvite precipitation is a useful method to remove ammonium ions from de-NOx scrubbing waste water. This study aims to investigate the effect of process parameters such as pH, molar ratio, reaction time and crystal size on the synthesis yield. The results showed that over 90% NH4+ removal was achieved through struvite precipitation. The stoichiometric molar ratio of 1:1:1 and 30 minutes of reaction time was found sufficient to utilize the residual NH4+ effectively from the wastewater, of which removal efficiency from the waste water was 93 %. The obtained crystalline precipitates distributed from 14 µm to 55 µm depending on reaction condition.
