Water- and Wastewater Laboratory

bioplan has its own water and wastewater laboratory. The focus of our investigations is on nutrient contents of surface water and wastewater, bioassays and the investigation of biological parameters such as chlorophyll, zoo- and phytoplankton. Since 2014, the laboratory has been DAkkS-accredited according to DIN EN ISO/IEC 17025:2005 and since 2018 according to DIN EN ISO/IEC 17025:2018.

Biotests and biological methods

Biotests are procedures that detect and quantify harmful water constituents by their effect on biological objects (fish eggs, plankton algae, bacteria, etc.). Selected biotests are carried out in our laboratory.
