Abstract This research aims to test the efficacy of Chitosan pellets that can affect wastewater treatment. By the release of waste water in the oil is vegetable oil 3. Oil and lubricant used in the experiment. Testing the efficiency of Chitosan pellets by verifying the physical characteristics, turbidity, color and odor as well as examine the chemical characteristics from measured values is acid alkaline (pH) of the waste water that contains a mixture of the three types of fat before and after making Chitosan experiment with scale volume 1 g. 2 g and 3 g here and three types mixed in the ratio 1:1, 2:1 and 3:1, it was found that better quality waste water after treatment with Chitosan is a Flake with a acid alkaline (pH) and the neutral of the three types of fats decreased noticeably from the study, it was found that the summary.Chitosan derived service naklet, used in the experiments, the most effective is the quantity of Chitosan pellets 3 g was Flake secondary Chitosan volume 2 grams and 1 gram, respectively, and found that the ratio of water and three types of oil are effective in trials is the ratio 3:1 second ratio 2:1 and 1:1 ratio, respectively.
