High protein effluent from laundry?s industry followed by dissolved oxygen decrease in water receive body. Waste processing through biologist process by using trickling filter which expented can be degradingthe content of BOD dan TSS. Tricking Filter have main unit such as media filter consists of stone pile as media growth of bacterial and occur contact between bacteria and wastewater. This research is done with use variable which is of flowrate (48,50,52,54, 56 ml/mnt) and re-circulation ratio (0,5;1;1,5;2;2,5) with parameter test BOD and TSS. Product of this research get the best degrade is with flowrate 48 ml/mnt and re-circulation ratio 0,5 can degrading 84,65% BOD of waste laundry?s industri and can degrading 84,69% TSS of waste laundry?s industri.} }
