Microbiological analytics

A made-to-measure solution for every problem. Integrated optimisation of treatment plant operation is a job for our specialists.

VTA microbiological analysis

Our VTA process engineers, biologists and chemists analyse all the processes that take place during wastewater and sludge treatment. Based on their findings, we offer:

comprehensive process engineering advice

individual solutions for each plant

accurate diagnoses and reports to accompany tests

Accurate diagnosis and individual solutions for each plant; this is our strength.

Biology

1

Regular microscopic examinations of activated sludge allow additional monitoring of ecosystem functionality at a wastewater treatment plant.

2

Number and composition of microorganisms indicate the respective operating condition, malfunctions and certain wastewater properties.

3

Toxic effects can often be detected even days after an incident using this method.

4

The experienced team of VTA biologists provides accurate diagnoses of special problems, reports to accompany tests or detailed expert opinions.

LIGHT MICROSCOPIC ANALYSIS

Microscopic analysis is a service offered by VTA and provides the opportunity to analyse activated sludge or scum samples from treatment plants in order to assess their operating condition.

This involves an examination of floc composition, number and diversity of microorganisms, filamentous bacteria and other components (such as emulsified fat droplets). The following statements can be made about the treatment plant based on the findings:

• Load and impact loads
• Nutrient ratio
• Oxygen supply
• Malfunctions
• Sludge age
• Fat content

An analysis report is then produced. This report can be used to indicate operating states or problems and suggest customer-specific solutions based on VTA system products.

We will analyse your sludge sample free of charge

Send us around 50 ml of activated sludge or scum along with your full contact details:

FLUORESCENCE ANALYSIS

Fluorescence analysis provides an insight into the ammonium and nitrite oxidising bacteria in a wastewater treatment plant.

These two groups of bacteria are important for a smooth nitrification process. Nitrification plays an important role in the nitrogen cycle of organisms. This process serves as an energy supplier for the growth of bacteria. In the event of insufficient nitrification, ammonium that has not been oxidised may be processed into ammonia that has a toxic effect on biocoenosis and the environment.

Gene-specific sensors are used to stain ammonium, and nitrite oxidisers that can then be detected in the activated sludge. 

With the aid of this specific analysis, living bacteria can be detected both quantitatively and qualitatively, and bacterial activity can be assessed.

An analysis report is then produced. Statements can be made about nitrification stability based on this report.

We will analyse your sludge sample free of charge

PINPOINT ACCURACY COMBATS FILAMENTOUS BACTERIA

Special VTA products inhibit the activity of the enzyme lipase, which filamentous microorganisms need in order to break down lipophilic substances in wastewater, i.e. for their functioning metabolism. In doing so, these VTA system products inhibit the growth of filamentous bacteria and are therefore ideally suited for combating bulking sludge and scum.

The effectiveness of the individual products depends on the respective general conditions. Measuring lipase activity can determine which special product from the broad VTA range is most effective in inhibiting the growth of filamentous bacteria in the specific application and will therefore lead to success in the fastest and most reliable manner.
Measuring lipase activity using ELF (enzyme-labelled fluorescence) technology is offered exclusively by VTA.
