Trickling Filter Methods. At some of our treatment plants we use "trickling filters" which pour water over tanks filled with rocks. The microorganisms live on the rocks which are surrounded by air. As the wastewater trickles past them they eat the waste and grow. This trickling of the water also provides oxygen so the microorganisms can thrive.
