Wastewater Microbiology

MCO would like to take this opportunity to formally welcome clients from Dr. Michael Richard.

We are honored to have a strong working relationship with him and value the opportunity to earn your business and trust moving forward. Over the years, Dr. Richard has provided training for many operators on our staff and has worked personally with Ryan providing support and continued education in wastewater microbiology and troubleshooting.

MCO wishes Dr. Richard and his family the best in his retirement and is forever grateful for the time he has spent mentoring our staff. We are honored to consider him a valued colleague and friend.

Midwest Contract Operations has professionally trained staff with extensive knowledge and experience in wastewater microbiology and consulting. The methods described in the 3rd Edition Manual on the Causes and Control of Activated Sludge Bulking, Foaming, and Other Solids Separation Problems (Jenkins, 2004) are followed in our lab. We have been recognized nationally through multiple agencies and have a proven track record of success.

Importance of Microbiological Analysis

Microbiological analysis of activated sludge systems, lagoons, filters or any biological treatment process is an invaluable tool for troubleshooting and suggesting effective remedial actions for wastewater treatment issues. Most problems identified through microbiological analysis can be corrected by simple operational adjustments, while others may need additional treatment such as chlorination to control or eradicate problem filamentous organisms.

MCO performs microscopic analysis of activated sludge and lagoon systems and provides detailed reports identifying filament(s) and other indicator organisms that are present. This information is then used to give likely causes for the presence of filaments and suggestions for their control.

Microscopic Evaluation Reports include:

  • Evaluation of floc size/strength
  • Dispersed growth abundance
  • Rank of zoogloea bacteria
  • Polysaccharide (reverse India ink stain)
  • Higher life form organism rank and abundance
  • Nitrifying bacteria, polyphosphate accumulating organisms, and other indicator organisms
  • Filamentous bacteria identification/ abundance/ impact on floc structure
  • Treatment recommendations based on evaluation.
