Abstract:An increasing number of wastewater utilities are reporting significant disruption of plant operations as a result of digester foaming episodes and, in some cases, costly structural damage to their digesters. The phenomenon of digester foaming is poorly understood and the literature on this subject is confusing. This paper reports on the results of a focused assessment that was undertaken to develop a better understanding of the phenomenon of digester foaming, its causes and, more importantly, means of mitigating its adverse effects. Armed with this information, wastewater utilities can make informed decisions on how best to “get a grip” on digester foaming.
