- Septicity in wastewater treatment plants occurs when microorganisms use up all the dissolved oxygen and nitrates in the sewage1. Without oxygen, anaerobic conditions develop and bacteria reduces the organic compounds to Sulphur and sulfide. Then sulfate-reducing bacteria utilise sulfates to form sulfides1. Septicity can be identified by the presence of black color, high sulfides, odors, and spirochetes/spirillum when viewed under the microscope2.
