MARINE SANITATION & WASTEWATER TREATMENT SYSTEMS

MarineFAST® Systems are commonly referred to as a Type II (two) MSD biological (aerobic digestion) treatment system. The Type II MSD systems are powerful, flow-through discharge devices and tested in conditions described in 33 CFR 159.121.

MarineFAST® Marine Sewage Treatment Marine and offshore sewage treatment systems built to handle extreme environments. All MarineFAST® (Fixed Activated Sludge Treatment) units are fully certified by US Coast Guard under U.S. and IMO regulations.

The MarineFAST® is a fixed film aerobic wastewater treatment system designed for the space and treatment standards of a maritime vessel, as either a new, complete system or a way to retrofit an existing system.

DIFFERENT REGULATIONS• IN MOST CASES, ONLY HUMAN WASTE AND GALLEY

WASTE ARE DEFINED AS “SEWAGE” AND ARE REGULATED.

• DISINFECTION OF EFFLUENT IS REQUIRED PRIOR TO DISCHARGE.

• CERTIFICATION OF UNITS UNDER MARINE REGULATIONS IS REQUIRED.

• EFFLUENT REQUIREMENTS CAN VARY CONSIDERABLY DEPENDING UPON LOCAL REGULATIONS.

DIFFERENT EQUIPMENT• ALMOST ALL UNITS ARE FURNISHED WITH TANKS

AND THESE ARE WATERTIGHT.

• PUMPS ARE NORMALLY REQUIRED TO DISCHARGE EFFLUENT.

• DESIGN FOR AMBIENT TEMPERATURE UP TO 50° C., ROLLING AND PITCHING SHIP, MARINE VIBRATION AND SEAWATER CORROSION.

SLIGHTLY DIFFERENT PROCESS• RAW SEWAGE ENTERS MEDIA TANK WITH NO

PRETREATMENT.

• SEWAGE ENTERS ABOVE THE WATERLINE.

• MEDIA TANKS INCORPORATE AIR SCOUR AT THE BOTTOM TO “SELF-CLEAN” BIO-GROWTH FROM THE MEDIA, BREAK UP SLUDGE BELOW THE MEDIA AND KEEP SLUDGE IN SUSPENSION DURING PUMP-OUT.

BACKGROUND• FIRST SUCCESSFUL PROTOTYPE ABOARD RIVER TOWBOAT IN 1969.• COMMERCIAL SALES STARTED IN 1973.• CERTIFIED BY US COAST GUARD IN 1975.• CERTIFIED BY CANADA IN 1978.• OVER 2,000 UNITS ON VESSELS AND OFFSHORE PLATFORMS.• LARGEST SINGLE UNIT 3,000 PERSONS BUILT INTO SHIP’S TANKS.• SMALLEST UNIT 6 PERSONS.• STANDARD UNITS AVAILABLE FOR CREW OF 6 TO 1000 PEOPLE.

ADVANTAGES• MEETS THE STRICTEST REGULATIONS IN FORCE WORLDWIDE WITH

STANDARD EQUIPMENT.• NO ADJUSTMENTS NEEDED OR REQUIRED.• PROPER OPERATION DOES NOT DEPEND UPON THE SKILL OF THE

OPERATOR.• EQUIPMENT AND CONTROLS ARE SIMPLE AND CAN BE SERVICED BY CREW.• SUPERIOR CONSTRUCTION, PROTECTION AGAINST CORROSION

MACHINERY AND CONTROLS MEAN LONG SERVICE LIFE WITH FEW PROBLEMS.

• QUALIFIED SERVICE AVAILABLE WORLDWIDE.

MarineFAST® 

HOW IT WORKS:1. Sewage enters the system. No need for a macerator or bar screen to clean or repair.

2. Quiet, compact BLOWER provides air through the piping system that connects to the airlift inside the media tank.

3. Aeration through the AIRLIFT circulates and aerates the tank contents to promote microorganisms present in sewage to grow and become fixed on Media to digest organic material. Media does not require replacement or cleaning.

4. From center line SPILLOVER pipe, treated effluent passes through TABLET CHLORINATOR and dissolves chlorine tablet proportional to the flow rate. Other disinfection methods are available.

5. Sized for peak flow periods, the Chlorine Contact Tank or WETWELL provides the chlorine enough time to disinfect treated effluent prior to discharge. Automatic Float Switches (shown in yellow) located in the center line of the tank gauge water levels for on/off operation.

6. A submerged EFFLUENT PUMP in the wetwell transfers the treated effluent to discharge out of the tank. Other transfer options available.
