Cutting edge technology that allows effectively treat contaminated groundwater
nitrates and nitrites in a clean and efficient manner for later use as drinking water.
Manages to reduce the nitrate content below 50ppm, legal limits stipulated for
The research project started in 2003 on a laboratory scale and the scale 2007
pilot plant. In 2008, the technology has been validated semi-industrial scale plant
The process consists of a catalytic selective hydrogenation reaction, through which
nitrates / nitrites are converted to nitrogen gas in a single stage, getting water
high quality without generating waste.
Contaminated water is mixed with hydrogen gas in a small reactor system
continuous, where the catalyst in getting clean water and nitrogen output
