APPLICATION OF OZONATION TO INTENSIFY NITRIFICATION AND DENITRIFICATION PROCESSES

Abstract

Nitrogen and phosphorus belong to most important biogenic macro elements and both are required for the growth of microorganisms. Sewage waste waters and industrial waste waters from nitrogen production are important sources of organic and inorganic nitrogen compounds in water. Surface water predominantly contains nitrogen in a form of ammonium cations (NH4+). This knowledge could be used in waste water treatment. The paper deals with a potential application of ozonation in waste water treatment to treat waste water polluted with excessive amounts of organic compounds, primarily containing nitrogen and its subsequent co-application with advanced oxidation processes (AOPs).
