Ultra Filter Sock Stop harmful substances from entering the stormwater system Compliance: 40 CFR 122.26 • Use in front of storm drains, around downspouts, in gullies and ditches or anywhere there is potential for harmful stormwater runoff. • Woven polymer casing allows water to pass through quickly while filtration media inside removes pollutants. • Available in 9-foot lengths. Units can be overlapped if longer coverage is necessary. • Looped ends allow units to be staked in place and also assist in transport. • Available with different types of media depending on what is the main pollutant that is present: • Sorb 44 — Used to remove oil and other hydrocarbons. • Phos Filter — Excellent for removal of phosphorous. • Activated Carbon — Excellent “polishing media”. Helps remove certain chemicals, hydrocarbons and odors. • Heavy Metal Removal — Custom filter media blend helps remove zinc, lead, copper and other harmful, heavy metals. • Sediment Removal - Recycled rubber media provides weight to keep unit in place while allowing maximum water flow. • Multiple Ultra-Filter Socks can be used in a “treatment train” if the potential for more than one contaminant or a large quantity of a single contaminant is present.
