Ultratech Filter Sock, Phosphorous, Removes Phosphorous - 9456

Place one or more UltraTech Ultra-Filter Sock in front of ditches, downspouts, gullies, or storm drains to help keep harmful substances from entering a stormwater system. Water quickly passes through the woven polymer casing, and filtration media inside the sock removes pollutants. Looped ends allow the sock to be staked in place and to ease transport. Units can be overlapped to cover larger areas or to handle a large quantity of a single contaminant. Or use different Ultra-Filter Socks where there is potential for more than one contaminant.
