They are used to treat sewage by allowing aerobic bacteria to decompose organic matter. Trickling filters are filled with rocks or other media that provide a surface for the bacteria to grow on. The sewage is sprayed over the rocks, and the bacteria decompose the organic matter. Sludge sedimentation tanks allow solids to settle out of the sewage.<\/p>\n<p>The correct answer is A.
