"Start-up of a demonstration-scale de-ammonification reactor at Bolivar WWTP";
AWA Water Journal,
Sludge dewatering effluent (SDE) is a small waste stream from sludge dewatering and digester processing in wastewater treatment plants (WWTPs)that is very high in ammonia and low in bioavailable carbon. SDE is commonly returned back into the activated sludge (AS) process, resulting in higher operational (aeration) costs and an unfavourable carbon/nitrogen (C/N) ratio for denitrification. Ideally, SDE should be treated separately and, of the processes available, deammonification is considered to be one of the most sustainable and cost-effective.
In collaboration with its Alliance partner, Allwater, SA Water investigated the efficacy of the deammonification process for removing nitrogen from SDE, as an alternative to AS treatment.
A demonstration-scale reactor was constructed at Bolivar WWTP in South Australia in 2012, based on Degrémontīs CleargreenTM technology. One of the key challenges of the treatment process is
the long start-up time, owning to the extremely slow growth rate of anaerobic ammonium oxidising (Anammox)bacteria, and so this paper reports on the process start-up phase. Under real conditions, results showed that Anammox bacteria were successfully enriched without seeding and stable deammonification was achieved within 280 days of start-up.
