C.I.Agent® Scupper Filters

The C.I.Agent® Scupper is a dewatering oil filter that ensures a compliant discharge of deck wastewater. It’s designed to fit below the scupper plug as a secondary line of defense but do not replace scupper plugs.

The C.I.Agent® Scupper Filter is a dewatering oil filter that is used in scupper drains on vessels to prevent oil contaminated wastewater (deck runoff) from entering the waters of the U.S. pursuant to Federal Statutes 33CFR Parts 155-157, CWA Section 311, 40CFR 110.3, and NPDES permits. The Scupper Filters encase C.I.Agent® solidifying polymers between two bags as the oil dewatering filter media. A proprietary coating on the outer bag makes it oleophobic and hydrophilic. The pre-filter filters out sediment, rust, scale, paint chips and debris.
