Let nature do the job !
New DNA technologies are creating unprecedented possibilities in the treatment of water, ground, air and waste materials. With these DNA techniques we develop new technologies to remove contaminants from your ground, water or industrial processes more cheaply and permanently. We characterise and accurately measure your biological processes so that you can let nature do the work. Our services are available for water treatment, soil remediation, ecology and industry.Contact

In the Netherlands muskrats are caught in order to prevent damage to dykes and embankments. It may sound strange, but it is true: muskrats can be detected using DNA techniques. The muskrat leaves a trace of DNA in the water. The trace comes from faeces, hair, skin cells and the …
ETBE and MTBE are used as oxygenate gasoline additives in petrol. In groundwater, the substances are mobile and poorly degradable (especially anaerobically). Under oxygen-rich conditions MTBE and ETBE can be biodegraded via TBA into harmless end products. Various bacteria are involved in this degradation. At an industrial site in Rotterdam …
Developments in the field of biotechnology provide new opportunities for ongoing soil remediations and monitoring. Every year there are new publications about micro-organisms that are capable of degrading contaminants; for example the publication in 2017 of the discovery of a benzene-degrading bacterial species. With our up-to-date knowledge and DNA technology, …
The ground on the WAVIN Services site in Hardenberg has been contaminated with solvents for a long time. These substances were formerly used as degreasing agents. WAVIN has been controlling this groundwater contamination since the 1990’s. Ground water was be pumped up and treated above ground. But this approach was …
We performed a biological source remediation in a residential location in The Hague (Gillesstraat). In the treated source zone we measured PCE (20,000 µg/l), TCE (2,900 µg/l), CIS (7,300 µg/l) and VC (
Scientific research does not stand still. New types of bacteria are being discovered every year, such as those involved in the degradation of benzalkonium chlorides (BAC, a cleaning and disinfecting agent) and in 2017 a species that anaerobically degrades benzene. Many contaminants can be degraded by bacteria, also in soil …
Looking for the cheapest remediation solution? Let nature do the work! Orvion develops remediation techniques using natural degradation processes. Only where nature is itself unable to degrade the contaminants, do we add carbon source, nutrients and/or bacterial cultures. Our motto is: remediate with the hand on the purse strings. Because …
When selling or redeveloping a plot or location, the suspicion of a soil or groundwater pollution being present brings along obligations. Orvion makes an inventory of soil pollution that are presen and a remediation strategy so that you not only know the extent of the contamination, but can also gain …
An industry wants to continue discharging its wastewater on a municipal wastewater treatment plant belonging to a water board. The alternative would be to build a new treatment plant on site, which would require a substantial investment. Arcadis is leading this project and approached Orvion to determine, by means of …
In 2016the Waterschap Rijn en Ijssel (Rhine and Ijssel Water Authority) suffered from inhibited nitrification at one of their treatment plants. The cause: a long-term discharge that was toxic to the nitrifying biomass. As a result ammonium in the sewage water was no longer successfully removed. This prompted us to …
