摘要
A process for reducing the content of nitrate in water to treat the required internationally to limit for drinking water (45mg / L), a process that includes Performing reduction of nitrates with hydrogen gas in Alkaline Medium. A variant of the process is performed in water previously Alkaline Reduction with hydrogen gas Rising.Another variant of the process is to carry out the Reduction with hydrogen gas countercurrent flowing through the alkalinized Water previously treated. The Invention comprises modular plants and / or the elements necessary to perform the processes.The process of the invention allows to obtain water with a Nitrate content below the permissible limit for drinking water according to international standards. The modular elements needed are very cheap and easy to install.
