Identification and Control of Filamentous Bacteria

The growth of filamentous bacteria in the treatment plant can cause operations and compliance problems such as bulking and foaming. The participants will learn a simplified method to identify filamentous bacteria, determine the conditions that favor their growth and methods to control and eliminate bulking and foaming caused by these microorganisms.
By the end of this course, you will be able to:

  • Identify different types of filamentous bacteria commonly found in activated sludge
  • Understand common causes for the growth of filamentous bacteria in the system
  • Perform microscopic techniques as well as QA/QC procedures, staining, and enumeration of filamentous bacteria
  • Understand process control adjustments required to control and eliminate filamentous bacteria growth in the treatment system

Wastewater Microbiology & Process Control

In this course, you will learn the role of bacteria, protozoa and metazoans in the treatment process along with the conditions that allow them the do their best work of removing nutrients from the wastewater. You will also learn how simple microbiological observations can be used to evaluate process efficiency and used to anticipate potential treatment system upsets and to troubleshoot and correct existing treatment system problems. By the end of this course, you will be able to:

  • Perform proper sampling techniques and laboratory QA/QC for simple microbiological analyses
  • Identify different classifications of microorganisms such as bacteria, protozoa and metazoans
  • Understand the role of different types of microorganisms and the significance of their
    dominance in the treatment system

Developing a Wastewater Microbiology Laboratory Program

The objective of this course is to teach the operators, lab personnel and consultants how to optimize the wastewater treatment plant processes using the microscope and knowledge of wastewater microbiology. This unit includes how to develop a wastewater microbiology laboratory program, and includes tools, techniques, and standard operating procedures used to perform wastewater microbiological analyses for treatment process control.

By the end of this course, you will be able to:

  • identify the different types of microorganisms; such as protozoa, metazoa, and bacteria
  • understand the importance of good sampling technique for microbiological analysis
  • classify groups of microorganisms and their characteristics within the treatment plant
  • demonstrate proper laboratory QA/QC procedures and documentation for monitoring and documenting microorganisms present in wastewater

Microbiological Monitoring of Biological Phosphorus Removal Systems

Participants will gain an understanding of the role of phosphorus accumulating microorganisms in biological phosphorus removal processes as well as an understanding of the requirements of their growth and for enhanced phosphorus removal. The course also includes microbiological methods to monitor the system microbiology for favorable and unfavorable conditions.

By the end of this course, you will be able to:

  • identify and troubleshoot treatment process issues as well as their causes
  • take corrective actions for process control
  • diagnose treatment system issues using the microscope
  • perform advanced microbiological process control analyses including protozoan/metazoan counts, filamentous bacteria counts, India ink and Gram staining techniques
