Directa Plus, a leading producer and supplier of graphene-based products for use in consumer and industrial markets, has announced the successful completion of industrial field testing of Grafysorber at an oil treatment plant of OMV Petrom, a leading Romanian integrated oil and gas company and one of the largest in Southern Europe.

The tests reportedly demonstrated that the deployment of Grafysorber improved the quality of water used for the injection process. The parties will work together on the second phase of trials to expand the tests to treat a further contaminant.

The purpose of the field tests was to examine the ability of Directa Plus’ Grafysorber, which was used in a dedicated treatment facility on a site of OMV Petrom, to remove petroleum hydrocarbons from produced water so that it could be used as injection water. The field tests demonstrated positive results in the industrial decontamination of produced water. In particular, Grafysorber was successful in significantly reducing the concentration of total petroleum hydrocarbons (TPH) in the produced water to less than 0.5ppm.

Other features observed during the field tests included:



  • High versatility: Grafysorber performed well in both high and low TPH concentrations.
  • High efficiency: The TPH concentration was quickly lowered to the desired value.
  • Sustainability: Only a small amount of Grafysorber was required to achieve the desired value. In addition, the used Grafysorber proved to be reusable up to 4-5 times, which meant that no waste was generated during the test. This complements the eco-friendly nature of Grafysorber, which isa 100% carbon material and does not contain any plastic.
  • Full compatibility: Grafysorber was able to be used alongside other additives to improve water clarification.

In March 2018, Directa Plus announced that it has entered into an agreement with Sartec to jointly develop a commercial-scale industrial system (Pilot Plant), based on the Company’s Grafysorber product, for treating oil-contaminated produced water in the oil & gas industry.
