ABSTRACT The increase in laundry activity in the city of Surabaya has led to an increase in the use of detergents, where the content in detergents has a bad effect on the environment. This study uses an adsorption method with commercial activated carbon upflow flow with flow variations of 5 ml / minute, 10 ml / minute, and 15 ml / minute with a height variation of 10 cm, 15 cm, and 20 cm and a sampling time of 2 hours, 4 hours, 6 hours, 8 hours, 10 hours and 12 hours. The results obtained were the highest efficiency from phosphate removal of 99.07% and anionic surfactant (detergent) 95.35%. The optimum discharge is 5 ml / minute with a height of 15 cm of phosphate and 20 cm of anionic surfactant (detergent). The suitable model is freunlidch, where the R2 value is 0.9418.
