Quantifying filamentous microorganisms in activated sludge before, during, and after an incident of foaming by oligonucleotide probe hybridizations and antibody staining

摘要

Quantitative oligonucleotide probe hydridizations, immunostaining, and a simple foaming potential test were used to follow an incident of seasonal filamentous foaming at the Urbana-Champaign Sanitary District, Northeast Wastewater Treatment Plant. A positive correlation was observed between an Increase in foaming potential and the appearance of foam on the surfaces of aeration basins and secondary Clarifiers. In addition, during the occurrence of foaming, the mass and activity of Gordonia spp.
