Sampling
The most important step in wastewater analysis is sampling. Only with appropriate and high-quality sampling methods can reliable and meaningful results be obtained.
Our field staff are specially trained for a wide range of sampling procedures and regularly update their expertise through internal and external training.
We carry out your required sampling, ranging from simple grab samples and qualified grab samples using stainless steel dippers to time-proportional, multi-day sampling using cooled automatic samplers.
Indirect dischargers
Wastewater treatment does not begin at central treatment plants, but already at the point of generation. This is where the foundation for controlled treatment is established.
On behalf of cities, districts, and municipalities, we monitor indirect dischargers. We are also happy to support wastewater producers directly within the framework of self-monitoring. Using suitable analytical methods, we ensure that discharged wastewater meets the requirements of the connected treatment facilities and help prevent unnecessary costs for the producer.
Whether testing is required under water law permits or local drainage regulations, we are happy to assist you with our expertise.
Direct dischargers
Direct dischargers bear significant responsibility for maintaining ecological diversity in the receiving water body. The monitoring of discharged, treated wastewater must be carried out in order to detect system malfunctions at an early stage. In addition, costs can be reduced through a reduction declaration in accordance with Section 4 (5) of the Wastewater Charges Act (AbwAG). This requires monitoring by an independent testing body .
Our qualified staff carry out the necessary sampling at your facility, and our laboratories subsequently analyze the samples using state-of-the-art technology.
Process monitoring
Depending on the type of system, wastewater analysis can also be used for process monitoring. Rapid response is essential in this context. Samples can also be delivered to us in person or by courier. They are processed as quickly as possible, and the results are transmitted to you digitally.
Activated sludge
The activated sludge process is at the heart of many central wastewater treatment plants. In this process, the pollutant load in the water is reduced with the help of microorganisms . This “diverse” mixture of microbes, protozoa, and bacteria is referred to as activated sludge and can be highly sensitive to fluctuations in the matrix. Key parameters in this process include sludge age as well as the concentration of filamentous bacteria and free-swimming bacteria, in order to prevent problems such as sludge bulking.
The examination of activated sludge is carried out microscopically and provides the most meaningful results when performed continuously. Regular analyses enable early detection of sludge bulking and help prevent avoidable disruptions in wastewater treatment.
