Who should attend

This course is designed for Laboratory staff, Chemist, Laboratory technicians, Environmental Specialist, Wastewater Treatment Plant Operators, Treatment plant engineers and anyone involved in microbiological analysis.

About the course

Upon successful completion of this course, the delegates will be able to:

  • Examine wastewater for biological characteristics, identify various organisms, perform particle size and number counts, and advise the operators of a wastewater treatment plant on the implications of the microbiological information developed
  • Understand how the changes in microbiological populations in a wastewater treatment plant can affect the plant performance and what to do to bring it back into the proper operation
  • Participants will also be able to use JNOPTIC Capture 2.2 software
