An apparatus, method, and system for treatment of industrial waste water and/or marine vessel bilge water before discharge into waterways, said waste water having hydrocarbon, and synthetic oils, chemical or surfactant based hydrocarbon emulsions, and water soluble hydrocarbons, containing hydrocarbon coated organics and fine suspended particulate matter, said treatment utilizing a hydrocarbon sorbing pre-filter media together with filter structural elements to first remove hydrocarbon contaminated organics and particulate, coalesce then bifurcate and adsorb heavier hydrocarbon elements; the remaining liquid entering the second stage of filtration wherein a cryogenically pulverized recycled tire powder material removes the remaining hydrocarbons, synthetic oils, hydrocarbon emulsions, and water soluble hydrocarbons, providing a highly clarified and oil free effluent at high flow rates and with substantially reduced filter system maintenance. Said invention may further contain a third stage utilizing another layer of hydrocarbon sorbing materials. It may be combined into an oily water separation system. |
