Heavy Metal and Hydrocarbon Filter and Methods of Use

Abstract

Mixed media tube or sock filters of variable length with mixed media designed to remove heavy metals and hydrocarbon contaminants, inter alia. The filters of the present invention can be used to control sediment in run-off from a construction site, as drain covers, or as retaining members for lawns or planting areas. A number of or a continuous length of such tube filters can be joined together to form assemblies which are useful for protecting a drain, series of drains, or other water mass, for example a pond or riverbank. Such tube filters can be synergistically joined with other environmental protection approaches, including but not limited to wattles such as ERTEC ProWattle https://ertecsystems.com/products/perimeter-sediment-control-four-types/prowattle-perimeter-control/, top guards such as Top Guard Drain Inlet Protection https://ertecsystems.com/products/top-guard-drain-inlet-protection/, curb guards such as Curb Inlet Guard https://ertecsystems.com/products/top-guard-drain-inlet-protection/curb-inlet-guard/, grate guards such as GR8 Guard https://ertecsystems.com/products/top-guard-drain-inlet-protection/gr8-guard/, and slot guards such as https://ertecsystems.com/products/top-guard-drain-inlet-protection/slot-guard/.
