The test was to remove petroleum hydrocarbons from the water produced as a by-product from oil and gas wells so that it can be reused.
In this test, Grafysorber reduced the concentration of total petroleum hydrocarbons (TPH) in the produced water to less than 0.5ppm.
Directa is working with Italian firm Sartec to develop the equipment needed to enable the widespread use Grafysorber in the oil and gas industry.
