Study on Denitrification of RO Concentrated Water Using Aerobic Granular Sludge

초록

영어

Reverse Osmosis(RO) concentrated waters are generally characterized by a high concentration of total dissolved solid(TDS) and nitrate. The one of the main problems in biological treatment of RO concentrated water is a cell disfunction and destruction caused by a high concentration of TDS[1]. Aerobic granular sludges have an excellent settleability and resistance to TDS up to a concentration of 80 g/L[2]. The aim of this study was to investigate the acclimation of aerobic granule sludge to RO concentrated water. The reactors was operated in a batch mode and fed with real RO concentrated water and methanol(CH3OH) as a carbon source with a COD/N ration of 3 g COD/g N. Aerobic granular sludges was gradually acclimated during batch mode. The removal efficiency of NO3 --N is increased from 35.82% to 96.93%. The value of the rate constant, K, for the kinetic equations also increased from 0.003L/g*hr to 0.059L/g*hr. It was concluded that aerobic granular sludges are suitable for RO concentrated water treatment process.
