ORVIbiotest – biodegradation testing (activity and feasibility)

We offer various tests in our laboratory. For water treatment, we have laboratory tests that quickly provide insight into whether wastewater can be treated biologically. You will receive information about the feasibility of the discharge requirement, the adaptation phase, the maximum degradation rate, toxicity, whether there is limited degradation due to a shortage of nutrients and, for example, the effect of temperature. No contamination-specific analyzes are required, which makes a significant difference in costs. The tests are performed with oxitop sensors and follow the OECD 301 F (manometric respirometry).

A lot is known about biological degradation of common contaminants such as chlorinated solvents, BTEX, naphthalene and oil. For sites with more exotic contaminants such as chlorobenzenes, pesticides or drins, more certainty can be obtained before the start of remediation about the chances of natural or stimulated degradation. For example, in degradation tests we can determine whether it makes sense to add nutrients, use alternative electron acceptors (such as nitrate or sulphate) or add a specific bacterial culture.

Available tests:

  • BOD testing: Determining biological oxygen utilization over time (BOD 28 days)
  • Nitrification: measuring nitrifying activity
  • Anammox: measuring anaerobic ammonium oxidizing activity
  • Fermentation: measuring biogas production from organic material
  • Aerobic biodegradation: determining whether a specific contaminant or wastewater stream is biodegradable.
  • Anaerobic biodegradation: determining whether a specific contaminant or wastewater stream is biodegradable under anaerobic conditions.
