The Microbiology of Wastewater
As your reliable partner for biological wastewater treatment, we provide support within the process optimization and the analytical quality control at the plant. With vermicon‘s products and services, a specific analysis, monitoring and control of the wastewater biocenosis are finally possible!
The tiny assistants of wastewater treatment plants
Biological wastwater treatment would be impossible without microorgansims, the smallest and most important assistants of wastewater treatment plants. Wastewater treatment plants are huge microbiological powerhouses, where microorganisms are responsible for the conversion of compounds and degradation of pollutants. Disturbances of the plant are usually based on disturbances of its microbial processes. Therefore, knowing the plant's biocenosis and thus being able to control its processes is essential.
Why can't wastewater bacteria be detected by conventional methods?
Conventional detection of bacteria nowadays is still based on the work of Robert Koch and is not adequate for the analysis of complex samples like wastewater. Scientific studies prove that up to 99,9% of all wastewater bacteria are non-cultivable. Due to their lack of specificity and the morphological variability and gram variability of bacteria, basic staining methods are also insufficient. To get a realistic image of the microbiological conditions in the wastewater treatment plant it is necessary to analyze the bacteria directly in the wastewater sample.
Why should you consider us the right partner for biological wastewater treatment?
VIT® Gene probe technology is the only method that allows a direct and highly specific detection of living bacteria in wastewater samples. Bacteria can be identfied, quantified and visualized.

What are VIT® gene probes?
Gene probes are tiny bits of genetic material, coupled with a dye. They enter and attach themselves to bacteria. Subsequently, the cells start to shine. Gene probes are designed to detect only specfic bacteria species or groups of bacteria. As a result, up to 100% of all known an unknown wastewater bacteria can be detected.
Bacteria in activated sludge
Interesting to know:
Activated sludge typically contains up to 5 billion bacteria per ml. The bacteria have an average size of 2-3 µm.
shape: "anything goes" - rods, cones, filaments, spirilla etc.
generation times (how fast bacteria duplicate): a few minutes up to several days
up to 99,9% non-cultivable: do not grow on nutrient media
the majority of bacteria lives in wastewater flocs
Monitoring of biological wastewater treatment
We will help you with the analysis of malfunctions, with identification of optimization potentials, and with the implementation of a targeted microbiological monitoring aiming at a prevention of malfunctions. You will receive true insight into the microbiological state of all releveant areas of biological wastewater treatment at your plant. This allows to detect changes in the bacterial populations, even before chemical parameter indicate a problem.
Are you looking for a solution to a specfic problem? We can provide support with the following wastewater treatment issues:
Degradation performance/ Populations
Sludge bulking and foaming
Biological phosphorus removal
Anaerobic reactor and anaerobic sludge
VIT® Vision - The Software for the wastewater biology
