Biosolids foam-over contained

A biosolids foam-over event from the Autoheated Thermophilic Aerobic Digestion system Wednesday morning was contained within the newly constructed containment area at the Three Rivers Wastewater Treatment Plant, according to James Baker, plant superintendent.

The containment area was constructed to serve as a final protective barrier to prevent biosolids foam from entering Lincoln Street and the city’s storm-sewer system.

The recently completed containment area performed as designed and prevented the release of more than 1,400 gallons of foam into the street, Baker said.

An automation system is in place to prevent high foam conditions within the ATAD, Baker said.
