MarineFAST® LX-Series Wastewater Treatment

Advanced Wastewater Treatment Systems are rapidly becoming the standard type of treatment system on cruise ships. These systems typically consist of a multi-stage treatment process that includes filtration, biological treatment, and disinfection of wastewater prior to discharge.

The LX-Series - This new economical and lightweight modular design is ideal for small commercial vessels. It is strong, corrosion resistant and will fit under the stairway of a tug engine room.

A simple and reliable method of dealing with accumulated sewage sludge on vessels and offshore platforms.  FAST® is the easy way to deal with sludge.

A standard MarineFAST® unit meeting MEPC.159(55) or providing secondary treatment incorporates about one (1) month of internal sludge storage. However, if you employ the next sized FAST unit, internal sludge storage can be increased to 3 months, without any additional equipment.


Description


MarineFAST_LXMarineFAST® Systems, are powerful, flow-through, Type II (two) Marine Sanitation Devices that are biological (aerobic digestion) treatment systems.  Tested in conditions described in 33 CFR 159.121, the MarineFAST® LX-Series Marine Sewage Treatment Systems are built to handle extreme environments.  All MarineFAST® LX-Series units are fully certified by US Coast Guard under U.S. and IMO regulations.

MarineFAST® LX-Series Certified Type II Marine Sanitation Devices (MSDs) to treat all blackwater and greywater generated on board.  Designed as an economical blackwater treatment system for harbor tugs and other small vessels, the MarineFAST requires no special training or expensive spare parts. It can handle any combination of fresh or seawater sewage. These marine High Strength Sewage Treatment Plants (HS-STP®) are IMO and approved worldwide. These systems have no moving parts in the treatment chamber(s) that are in contact sewage and nothing to corrode. Whether full crew or little to no crew, the MarineFAST® self-regulates, handling surges, overloads and light loads without problems. In fact, each MarineFAST® unit does this better than any other biological treatment system and is fully certified. The best part of all, it requires no manual cleaning.
HOW IT WORKS:


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.

How It Works

MarineFAST® - How It Works:

MarineFAST_flow_diagram

  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.

EFFLUENT STANDARDS
Check which effluent requirements you must meet.

  • USCG 33CFR159 – Minimum 33CFR159 / MEPC.2(VI) standards for 150 TSS, 200 fecal, certified by U.S. Coast Guard installed aboard vessels and not subject to effluent sampling in service not required by regulations.
  • MARPOL 2010 – 25 BOD5, 35 TSS, 125 COD, 100 fecal effluent for USCG certified units and recommended for general marine use with 2 months internal sludge storage and dechlorination of effluent. Secondary treatment may be required for restricted waters, barges meeting local or harbor regulations, and offshore applications that are subject to state or other regulations.
  • USEPA Secondary Treatment – Applications requiring 85% removal, 30 BOD5, 30 TSS secondary treatment, 3 months internal sludge storage, and derate by 10% for dilute sewage.

Why Scienco/FAST Systems…

MULTIPLE APPLICATIONS IN EVERYDAY SERVICE
With decades of proven results and more than 50,000 land/marine installations, FAST® systems have been used from harbor tugs to cruise ships and from single homes to small cities. The largest MarineFAST systems process more than 195,000 gpd (739 m3/d) and the largest land FAST systems process more than 1.5 mgpd (5,680 m3/d).

PROVEN TECHNOLOGY
With more third-party certifications, technology approvals, and awards, Bio-Microbics, Scienco/FAST, and SeptiTech are known for its decentralized wastewater (total blackwater/greywater) treatment technologies.  These systems have performed exceptionally well in achieving higher levels of nitrogen removal and optimal effluent quality with automated operation and energy-efficiency required in today’s standards and regulations. In addition, the treatment quality our expanded product offering can help meet most, if not all, onsite application goals.

Fully certified by the US Coast Guard under 33 CFR Part 159 and IMO rules, FAST® (Fixed Activated Sludge Treatment) treatment systems can be found around the globe in offshore, municipal, industrial, commercial and residential applications. The reason for FAST’s success is its ability to provide years of reliable trouble-free service without adjustments or the need for a skilled operator.

SIMPLE PROCESS
Using ordinary pumps, blowers and controls already familiar to vessel personnel, the sophistication of the BMS component is inherent in the state of the art process and the know how needed to get maximum benefit from it.

OTHER BENEFITS
Aerobic process and ABS deep tank standards – no corrosion or terrible odors. All machinery, piping and controls meet USCG requirements for inspected vessels.

Also, FAST is already capable of meeting the next generation of sewage regulations. This protects you from changes in the regulations or from individual foreign or local regulations which exceed minimum USCG certification requirements.

Worldwide Service

With vessels circling the globe, service questions often arise. Service is available worldwide, with equipment manufactured in the United States, Canada and Australia.
