Abstract:
Devices and methods are provided for filtering contaminants or pollutants from water, such as rainwater or stormwater. The devices include a liquid filter comprising a tubular mesh enclosure containing a filling. The filling comprises compost particles and an activated carbon material. The compost particles have a bulk particle distribution of more than 30% less than 0.375 inches and at least 90% less than 2 inches. This unique combination of particle sizes and filling materials increases the removal efficiency of the filter. In addition, this filter media absorbs a broader range of industrial pollutants than conventional filters.
