The NH4+ exchange capacity of natural zeolite depends on the location of extraction and on the ion contents of the waste water to be treated. The NH4+ exchange capacity is determined for each zeolite and waste water sample individually in the current design method of NH4+ removal equipment. Therefor, these results cannot be generally applied to other cases. In this study, the equation to obtain the design velocity of treatment through the zeolite packed cloumn by the cation exchange capacity and particle size of zeolite as well as the ammonium concentration and temperature of water was investigated. In addition, the experimental equation to show the ion exchange equilibrium from cation contents was obtained. On the basis of the investigation, the simple method to obtain the design variables was developed.
