The Bilge Filter System
The Bilge Filter (TBF) is simple flow thru filter system that works with any bilge pump and removes oils from your bilge water. The Bilge Filter system uses the same filter media that we use on the BRUTE/ B USCG/ABS/BV certified oily water separators.
The #TBF3X system ass’y has 1 sediment filter and and two OilSmart oil removal filters with a gate valve and pressure gauge, that can work with any bilge pump. It plumbed, assembled and ready to be installed with just a simple inlet/outlet connections. With the #TBF3X system we can mount a IMO/MEPC 107 (49) oil content monitor behind that is USCG/ABS/BV certified and you can have a clear record of your oil in water discharges. The monitor can log the last 18 months of discharges thru the unit. Every time your pump kicks on——–it’s logged.
Want proof you are not over limits on oil?

How about TheBilgeFilter with an Oil Content Monitor?
This does not make it a separator — but it does give you a USCG approved monitor that shows the water quality of the water discharged thru this system. Unlike a full blown marine oil water separator that is usually a minimum of 30” square and 6′ tall, The Bilge Filter with the monitor is only 30″ high by 30″ wide x 8″ deep
These oil content monitors come with a 5 year certification which means it is certified to meet IMO/MEPC 107 (49) requirements for 5 years——-as long as the seal on the unit is not broken or missing. After 5 years it has to be re-calibrated to be certified as compliant with regulations. Big trouble awaits you if your monitor is out of certification because you would then be out of compliance with IMO/MEPC 107 (49) requirements and operating illegally. While there are a few recalibration services around, doing that takes you out of operation. The solution or work-around for that is simply getting a new measuring cell and simply installing it on your oil content monitor and you are then instantly recertified for another 5 years——-as long as you don’t break the seal on the measuring cell. It’s a simple quick installation and you’re back in business and back to being certified. Contact us directly for a certified replacement measuring cell.
Gives you a legal record of the water you’ve discharged thru the system. Shows the USCG — you’re trying to do the right thing. If you are not mandated to have a separator, this could be the answer. For 1/3 the size and cost of a Oil Water Separator!
