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

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 …
Antibiotic resistance (ABR) is seen as one of the greatest threats to public health. Already every year in Europe more than 25,000 people die from the consequences. These people are often already seriously ill. But young healthy people are also increasingly being hospitalised as a result of infections, such as …
In water treatment it is bacteria that clean the water. So data about the micro-organisms in sludge is needed in order to have more insight and more control over the treatment process. With new technology from Oxford Nanopore Technologies that we use, this has become possible and affordable. An example …
Client: Logisticon Water Treatment Question: A very highly loaded MBR bioreactor (average influent concentrations COD 15.000 mg/L and ammonium 4.000 mg-N/L) showed Nitrite accumulation (up to 1.000 mg/L) and didn’t function properly. The question was to find the underlying problems and advise on the optimization of the process in order …
Client: Water Board Schieland and Krimpenerwaard Question: A watertreatment plant periodically has problems sludge bulking, the question was to analyse with ORVIdetect quantitative PCR to gain insight into the filamentous growth in the sludge. Work done: ORVIdetect analyses for several filamentous micro-organisms were performed on the sludge. At the moment …
