Operational demonstration of innovative and sustainable nitrate elimination in stainless steel pickling by higher power biological denitrification technique - NITRATEBIO DEMO

Description: The most important stainless steel pickling acid in use is the mixture of nitric and hydrofluoric acid. Nitrogenous compounds in the arising pickling process water have to be eliminated before the disposal of wastewater. In the forerunner project 7210-PR/358 the great advantage by the application of high-power bio-treatment for elimination of nitrate was shown. The industrial application of the developed process by this pilot and demonstration project is completely new and innovative. It is a logical and important step to a zero nitrate emission strategy for pickling with nitric and hydrofluoric acid which helps to save water resources.
