Abstract:	The research about base activated clay and its application as cation exchanger to reducing the concentration of ions Mg2+ and Ca2+ in the well water has been carried out. Base solution used for clay activation was NaOH with variation of concentration at, 0.5 M, 1 M, and 1.5 M. Particle size of clay also have been varied at 40 mesh, 60 mesh, and 80 mesh. The result of this research shown that the best cation exchanging for Mg2+ was found in clay with 60 mesh particle sizes and concentration of NaOH 0.5 M, whereas for Ca2+ was found in clay with 80 mesh particle sizes and concentration of NaOH was 1.5 M.
