Biodegradable Runoff Filter

摘要

A biodegradable runoff filter is an apparatus that is used to filter silt, chemicals, and other contaminants out of water runoff produced at or near a work site. The apparatus includes a biodegradable filter sock, a botanical biomass filling, and a fastener. The biodegradable filter sock is a water-permeable container that is used to contain an amount of the botanical biomass filling. The biodegradable filter sock includes a lateral portion, an open end and a closed end. The lateral portion and the closed end surround the botanical biomass filling and contain it to a specific area. The open end of the biodegradable filter sock allows the botanical biomass filling to be packed into the biodegradable filter sock. The fastener fits over the open end and cinches the open end shut to prevent the botanical biomass filling from falling out of the biodegradable filter sock.
