Trickling filters at a sewage treatment works. Trickling filters are a type of aerobic wastewater treatment, where sewage or wastewater flows down into a bed of rocks. The flow of wastewater promotes a layer of microbial slime to grow on the bed. Pollutants are removed from the wastewater through adsorption and absorption of organic matter by the microbial layer.
