Welcome to Scienco/FAST ®

Proven Marine Sewage Treatment
System.

At Scienco/FAST®, we build marine and offshore wastewater treatment systems that deliver real-world performance – not just in land certification tests. Our award winning FAST® (Fixed Activated Sludge Treatment) process has become the trusted choice for vessels, platforms, and remote operations worldwide.

The Marine/FAST Advantage – Simple. Low
Cost. Robust

The Scienco/FAST® process consistently meets the most stringent effluent regulations without the need for trained operators or constant adjustments. Whether dealing with blackwater, graywater, ground food waste, freshwater, seawater, vacuum or conventional toilets, Scienco/FAST® handles it all.

Built for Tough Environments

Our systems are engineered to outlast and outperform in harsh marine conditions

Steel Tanks:

Built to ABS Deep Tank Standards, these tanks are as tough as the vessel itself – designed for strength, longevity, and shipboard durability

Polyethylene Tanks:

Certified for hazardous waste transport by DOT, they resist marine corrosion, vibration, and chemical exposure

Superior Corrosion Protection:

Every tank is grit-blasted to white metal, coated with epoxy resin, and welded on both sides – far exceeding industry norms.

No Spares Needed – Just
Built-In Reliability

Unlike other systems that require redundant treatment units, FAST systems are designed to last – with optional dual blowers or duplex pumps for added assurance, not necessity.

Testimonials

We just replaced an original FAST unit that was installed in 1972 on a line boat, with a new one. I would say they sure make these to last.

Bill K.
Chief Port Engineer

Sciencofast made an exact custom duplicate of the system we have on our ship, to replace this one, which lasted 32 years.

Jim P. Cheng

After buying a new tug, and the builder installed a cheap plastic MSD from another company, and it only lasted 4 years, we installed a FAST system and WOW what a difference!

Dan O.
Captain

We always use FAST systems, and never have had a problem with inspections.
