Abstract:
1. An apparatus for the filtering of industrial waste water, said waste water being an emulsion mixture having hydrocarbon organic contaminants including synthetic oils, chemical or surfactant based hydrocarbons, water soluble hydrocarbons, oil coated organics, with fine suspended particulate matter contaminants, said apparatus comprising: a cylindrical cartridge shaped enclosure; a first and a second filtering stages encased within said enclosure, said first and second filtering stages being structurally geometrically configured as separate concentric cylindrical sections within said cylindrical cartridge shaped enclosure, the first filtering stage being located in the outer periphery of said cylindrical cartridge shaped enclosure, the second filtering stage being located concentrically inside of said first filtering stage, said waste water emulsion mixture entering said apparatus on said first filtering stage's outer periphery and then being directed to flow radially inward through said first, and then said second concentric cylindrical sections, said first filtering stage having a hydrocarbon sorbing pre-filter media to first remove hydrocarbon organic contaminants and fine suspended particulate matter contaminants then coalesce, bifurcate and adsorb hydrocarbon elements, then said waste water emulsion mixture flowing radially inward entering said second filtering stage, said second filtering stage having cryogenically ground rubber powder to further remove said waste water emulsion mixture's hydrocarbon organic contaminants and fine suspended particulate matter contaminants, said apparatus having cylindrical baffles located concentrically inside of said second filtering stage at the top and bottom of the apparatus, said apparatus having top and bottom covers that enclose the top and bottom of said concentrically arranged first and second filtering stages, said apparatus having a clean discharge for the contaminant free waste water to exit said filter, said hydrocarbon organic contaminants and fine suspended particulate matter contaminants being structurally and mechanically trapped from breaking through the top sections of the filter's first and second filtering stages and entering said clean discharge by said cylindrical baffle located in the top and bottom section of the apparatus together with said top and bottom covers.
