The research was carried out to exploit the use of zeolite for phosphate absorption in the water. The result shows absorption of phosphate into 35 mesh Zeolite from Bayah and 5 ml/minutes stream velocity is 78 to 82 % while that into 50 mesh zeolite from Sukabumi and 5 ml/minutes stream velocity is 80 to 87 %. The saturated zeolite can be regenerated by 0,5 N NaOH.
