The UltraTech 9456 Filter Sock, PhosFilter is an above-drain stormwater filtration device engineered to remove phosphorus from runoff before it enters storm drains, downspouts, gullies, ditches, and other drainage systems. A woven polymer casing contains specialized PhosFilter media that allows water to flow through while capturing phosphorus and associated contaminants. The 9-foot-long design can be used individually or combined with additional filter socks to create extended treatment barriers for stormwater management programs.
- Phosphorus Removal Media – Specialized PhosFilter media is designed for effective phosphorus removal from stormwater runoff before discharge into drainage systems
- High-Capacity Filtration – Each filter sock can remove up to 26 lbs. of phosphorus with removal efficiencies of up to 95% under suitable operating conditions
- Woven Polymer Construction – Durable geotextile casing allows rapid water flow while retaining filtration media and capturing targeted pollutants
- 9-Foot Modular Design – Units may be overlapped to create longer treatment zones or combined with additional filter media types in a treatment train configuration
- Looped End Configuration – Integrated loops allow staking for stability and simplify transportation, placement, and retrieval
