Investigating the use of anaerobically stored carbon in post-anoxic denitrification.

ABSTRACT: Significant methanol savings are hypothesized to result from anaerobic storage of internal carbon that is used for post-anoxic denitrification. An investigation into this internal carbon-driven denitrification was performed via a series of batch tests using biomass from Hampton Roads Sanitation District's (HRSD's) water resource recovery facilities (WRRFs): the Virginia Initiative Plant (VIP), Nansemond Plant (NP), and Army Base (AB) Treatment Plant. Internal carbon specific denitrification rates (SDNRs) increased during winter, by as much as 1 mg N/g MLVSS/h for VIP. Increasing the aeration time by 2-4 h lowered the SDNR by an average of 0.21-0.35 mg N/g MLVSS/h. No internal carbon denitrification was observed for biomass from non-nitrifying/denitrifying, biological phosphorus removal (bi
