Trying to determine what you might be seeing under the microscope and whether it is good or bad? The following categories of microorganisms are seen in wastewater treatment to varying degrees in every plant. While the single-celled bacteria are those that reduce BOD, the presence or absence of these “higher life forms” can communicate the health or change in the health of the biological wastewater process. Click on the category for a brief description and photomicrographs taken at EBS representing those organisms. If you have any questions on what your system is showing or experiencing, the EBS laboratory team will be pleased to assist you in this area.
