Adsorption process can also establishes a mathematical relationship between the interaction process of variables and process optimiza�tion is essential in measuring factors values to obtain maximum respons number.The adsorption of Fe from ground water was optimized by using the methodology of response surface based on design idea of Box-Behnken. Adsorption data was analyzed using isotherm mod�els. The process was measured using continue experiments. Variables in the process were bed depths (7,5, 10 and 12,5 cm), time (20, 40 and 60 min), flow rate (6, 10 and 14 L/min). Regression analysis was used to analyze the value of models developed. The result of this research showed the number of 95,598 % from the variations in removal rate of efficiency respectively are applied to three processes which variables considered, that is, bed depths, time and flow rate. Therefore, the models used as well to predict the interaction of the process variables. Optimization tests showed the optimum process conditions for the adsorption process occurred at bed depths 11,36 cm, time 55,61 min and flow rate 6 L/min. These were considered as optimum operating conditions. There are two isotherm equations which have been tested, those are Langmuir and Freundlich. The Equilibrium adsorption data can be optimized when formulated in the Lang�muir isotherm model
