	Rezime:
	Research was made on a rarely applied form of biological ammonium removal, a rapid filter (with at least 5 m/h flow velocity) dedicated solely for nitrification. A model equipment was operated with raw water of relatively high ammonium content (> 2,5 mg/l), in order to gain information about the limits and capacities of this method. Results have shown that this process can remove the requested amount of ammonium, efficiency is stable enough and the biological growth can be easily controlled by simple backwash methods. Further research needed to observe the effect of operating conditions (hydraulic load, filter geometry, backwash strategy) and water quality (mainly alkalinity, iron and manganese content) on the efficiency of nitrification and nitrogen balance. The aim of the research is to study such a nitrifying rapid filter that can reduce the ammonium load for the subsequent drinking water purification process steps, and provides an alternative of breakpoint chlorination and other expensive technologies.
