Influence of free ammonia on the performance of a polyhydroxyalkanoate (PHA) microbial enrichment sequential batch reactor (SBR) at pilot scale

A pilot-scale PHA microbial enrichment reactor fed on OFMSW leachate was monitored in order to assess the influence of free ammonia nitrogen (FAN) on its performance. The enrichment reactor consisted of a SBR with a 12-hours cycle which included a feast phase, a settling phase and a famine phase with external nitrogen addition. Based on the...
