redFox Environmental Marine Sewage Treatment


Separator Spares & Equipment, LLC is the Authorized Marine Distributor for redFox Environmental Services for the Gulf Coast region.

RedFox Marine Sewage Treatment units are US Coast Guard Approved according to 33CFR Part 159. They are also IMO type approved Sewage Treatment Plants according to IMO resolution MEPC.227(64). MEPC adopted MEPC 227(64). This ostensibly changes the discharge requirements and test protocols that are adopted by Resolution MEPC 159(55). Their specific aim is to reduce nitrogen and phosphorous from the treated water, which will prevent the acceleration of nitrification of the seas. 

redFox Standard Marine Series:

The redFox Environmental Marine Series Units are Bureau Veritas certified for IMO Resolution MEPC 227(64). The IMO Marine Environmental Protection Committee resolution applies to all sewage treatment systems installed on-board on or after January 1, 2016. The Marine Model is designed, manufactured and tested to meet or exceed MEPC 227(64) effluent standards.

redFox Standard Marine Sewage Units Features & Advantages:

  • The redFox Marine Series clarifier operates under a fluid head pressure allowing flocculation and settling solids in the clarification chamber to occur even when the vessel is in motion.

  • The clarifier chamber is totally enclosed and between 400 and 600 mm lower than the waterline in the aeration chamber. This ensures the water discharge quality is superior to all of our competitors. Our competitors utilize an open style clarifier and are susceptible to problems caused by vibration and rolling seas. Solids do not settle properly and will negatively affect the discharge water quality.
