Abstract
A method for producing a fertilizer that comprises urea and/or at least one ammonium compound may involve obtaining ammonia as an impurity in the production process, and photocatalytically decomposing the ammonia by irradiation with UV radiation. Further, an apparatus for producing fertilizer granules that comprise urea and/or at least one ammonium compound may include a plant section having a fertilizer granulator configured to produce the fertilizer granules, a supply line configured to pass a urea melt or a concentrated urea solution to the plant section, a UV lamp arrangement that is proximate the supply line and is configured to irradiate with UV radiation the urea melt or the concentrated urea solution flowing in the supply line.
