Our heavy duty double-layered socks made from ADsorb-it® Filtration Fabric will filter silt, oil, oil sheen, and oil-borne contaminants from water discharges. They can be made in any size for your individual needs. ADsorb-it® filtration fabric provides approximately 100 micron filtration, thus the Filter Sock will act to reduce silt levels in discharge waters as well as filtering out oil, oil sheen, and oil-borne contaminants. The SFS8-5SL is a Single Layer version of our regular SFS8-5 Filter Sock. We can design and manufacture specialty filter socks for your specific application.
