Filamentous bacteria can cause operational problems for clean-water plants and are typically a symptom of a process upset that needs correction.
Different filamentous morphotypes point to different conditions, and operators can benefit greatly from being able to identify the various strains using phase contrast microscopy and make appropriate process adjustments based on their findings. Midwest Contract Operations, a company based in Neenah, Wisconsin, that provides hands-on technical support to municipalities, utilities and industries, has published an updated handbook of wastewater microscopy emphasizing methods of filamentous identification.
The company provides microscopy interpretation services to clean-water organizations throughout the United States and Canada.
