Abstract
Detergent is one of a real detergent material popular in Indonesia. However waste yielded has negative impact that is existence of liquid waste contaminating area. Liquid waste yielded is organic trickling type of which is not easy to elaborated by bacterium. This research addressed to know operating condition of the action of disentangling detergent waste applies trickling filter. Research done at detergent brand Rinso Anti Noda, Daia, and Attack Softener with variable changed time that is 0, 1, 2, 3, 4, and 5 hour. First step done is animates bacterium at tile media during 40 days in domestic sewage of the moat, then puts down fraction of tile equaly in each tray, fills detergent waste and installs pump at collecting vessel under. Detergent waste will flow and wetts fraction of tile in each tray so returns again at collecting vessel under, then is pumped again, so further so happened circulation and then does analysis LAS at each waste sample. The more circulation time needed to reaction then the least LAS content. Result obtained in the form of degradation of rate LAS per hour, at detergent Rinso Anti Noda, dc/dt = 0,0228; Attack Softener, dc/dt = 0,0254; Daia, dc/dt = 0,0394.
Key words : detergent; LAS ; trickling filter
