Activated Sludge: Filamentous Organisms (26S-ETC103) (3 TCH’s)

  • June 23, 2026 8:30 am EDT
  • 3 hours
8:30 AM – 11:30 AM Eastern This course is sponsored by NEIWPCC in conjunction with the EPA. Instructor(s): Michael Gerardi provides a description of filamentous organisms based on their morphology (structure) and response to differential stains. The class reviews the positive roles performed by filamentous organisms at an acceptable level of growth as well as the negative roles performed by filamentous organisms at an unacceptable level of growth. Growth stimulatory conditions, modes of operation, and industrial discharges that promote an unacceptable level of filamentous organism growth are identified. Corrective measures for the unacceptable level of filamentous organism growth are reviewed. Also, foam-producing filamentous organisms are identified along with control measures for the growth of the organisms and foam are offered. Numerous photomicrographs are presented. Wastewater Training Contact Hours (TCHs) are approved in CT, and MA. Participants must attend the entire session and participate in polls to receive TCHs. Links to certificates will be emailed to participants upon course completion. All participants must be registered to view the course. Registration closes when the class starts. Cancellations must be received at Training@NEIWPCC.org no less than 24 hours prior to course start time.”
