2 Rotating arm Distributes liquid waste Filter media Biofilm-coated plastic pieces or coarse gravel and rocks Liquid waste trickles through 5 Outlet pipe Liquid waste from the filter goes to a sedimentation tank before 1 Inlet pipe Liquid waste from primary treatment enters advanced treatment or disinfection FIGURE 29.2 Trickling Filter Wastewater is channeled into the rotating arm, and then trickles through holes in the bottom of the arm onto plastic or a gravel and rock bed.
