Microsurvey is an environmental biotechnology company specialised in troubleshooting problems at wastewater treatment plants. The company operates internationally and participates in collaborative projects with universities and scientific researchers throughout the world. Extensive plant operating experience has led Microsurvey to an understanding of microbiological community structures as the driving force of system optimisation. Microsurvey has extensive knowledge of managing wastewater treatment systems to control bulking, for example, or to improve nutrient removal capacity.



Working with Microsurvey directly reduces costs and ensures a reliable treatment. Its long-standing experience guarantees comprehensive know-how and the reliable completion of projects to the highest standards.


The interdisciplinary services of Microsurvey are:

  • Problem solving and process optimization in wastewater treatment systems
  • Advice on all aspects of industrial and municipal wastewater treatment
  • Contract research, Feasibility studies
  • Supervision of trials during the introductory phase of new technologies
  • 'On-the-job' training for operators, laboratory staff and plant managers
  • Microscopic examination of activated sludge and biofilms
  • Molecular-genetic analysis (FISH, FISH-MAR, DGGE, RT-PCR)
  • Image analysis, Telemicroscopy Systems
  • Process automation, Telemetry


Image Analysis

The common approach of microscopic examination of activated sludge can be criticized for several reasons. Certain parameters of the microscopic analysis are subjective to the trained level of the analyst, which make interlaboratory comparisions very difficult. Also the use of subjective morphological criteria to describe basic properties such as floc structure and the subjective scoring system of estimation of the abundance of filamentous microorganisms ...

Problem Solving

Upsets in process operations still remain quite common in both domestic and industrial activated sludge plants. Process problems in wastewater treatment plants can often be traced to the microbial community. For example, excessive growth of filamentous bacteria, responsible for filamentous bulking in activated sludge plants. Although a considerable amount of effort has been dedicated to activated sludge process engineering analysis, surprisingly little ...
