FAST® processes raw, unscreened sewage as it is produced

FAST® units are capable of handling any combination of blackwater, graywater, ground food waste, freshwater, seawater, vacuum toilets and conventional toilets. No macerators, grinders, pretreatment or flow equalization tanks are required.

The process is very turbulent and the airlifts used for oxygen transfer throw foreign objects to the sides of the tank where they will not interfere with the process. There are no moving parts in contact with sewage, no filters, membranes or fine pore aerators to blind or plug.

FAST® units provide outstanding effluent quality without any filters or membranes. Consider official testing under three separate regulations over a 50 year span and with standard production units:

Parameter

Canadian Great Lakes
Official Test Results 5.3 2.76
Effluent Requirement 50 50
US Coast Guard 33CFR159
Official Test Results 3.2 4.2
Effluent Requirement n/a 150
MEPC.159(55)
Official Test Results 4.1 5.8
Effluent Requirement 25 35
Definitions
BOD5 – 5 day biochemical oxygen demand
TSS – total suspended solids

Many biological processes are upset by light loading. The only effect on FAST® is that the effluent quality is even better.

FAST® starts up much faster than conventional suspended growth processes. Also, FAST® is self-starting without powdered bacteria or activated sludge from another sewage treatment plant. In the real world, all biological processes are upset from time to time. FAST® handles these quickly and automatically and no operator intervention is required.

All processes capable of removing pollutants to meet MEPC.159(55), US EPA and other secondary effluent standards produce a residual sludge that requires separate disposal – that is, all processes that do not employ dilution to meet standards.

The FAST® process supports a more complex microbial culture than conventional suspended growth systems. Segmented sludgeworms, insect larvae and other higher ordered organisms predate upon simpler microorganisms and reduce the mass rate of sludge accumulation by one-third or more.
At the same time, FAST® sludge is heavier and more concentrated than that from suspended growth systems of all types (including MBR’s). In volumetric terms, the net result is a rate of sludge accumulation of much lower than that of other processes.

There is no need for operators to come into contact with sewage at any time.

FAST® is truly a state of the art process. Operating weight is less than half that of comparable biological units.

The smallest FAST® units are sized to handle harbor tugs and individual homes. The biggest systems so far handle 195,000 gpd from 1,750 persons aboard a cruise ship and 1,500,000 gpd from a municipal system at Tokoroa, New Zealand.

Steel tanks are designed to meet ABS Deep Tank standards. This provides a strong foundation for a superior coating system. Many FAST® units remain in everyday marine and offshore service after 30 years of continuous operation. When requirements change, these units can be and are updated at minimal cost.

With such long service lives, older FAST® units can be and are upgraded to meet the latest regulations when so required. Although the process technology is state of the art, the components are simple and economical.

New Certifications

The MarineFAST® technology utilizes a unique hybrid method of fixed and submerged treatment processes to both effectively treat wastewater and provide a system for management of biosolids. the treated effluent disinfection methods involve chlorination, chlorination/dechlorination, and now peracetic acid.

Scienco/FAST® has been awarded USCG and Transport Canada certifications for our MARPOL configuration FAST® systems using peracetic acid (PAA) as the disinfectant.

As a disinfectant, PAA is as effective or more effective than chlorine. PAA consumption should be about one-third that for sodium hypochlorite laundry bleach.

At the same time, PAA has no adverse environmental impact as chlorine does. There are no carcinogenic or mutagenic byproducts and PAA is fully approved by EPA for disinfection of sewage treatment system effluent.

We are now able to offer two alternate versions of every standard FAST® MARPOL certified unit, (a) with chlorine disinfection and (b) with PAA disinfection. In addition, the use of PAA simplifies and substantially reduces the cost of our MARPOL certified FAST® systems.

It represents a genuine improvement in many ways. PAA is available from Solvay Chemical and other suppliers and we will be stocking suitably sized containers for our customers.

Marine sanitation treatment systems treat sewage from offshore work applications and help lessen the environmental impact of contaminants.

MarineFAST® sewage treatment systems are also certified by the US Coast Guard’s USCG and International Maritime Organization’s MEPC.159 (55) effluent standards. As an effective marine sanitation device, the MarineFAST® adheres to the highest standards in the marketplace and versatile to fit in any configuration and size of vessels and offshore platforms.

Typically, the certification process involves thorough testing of how the system handles shock and vibration in the most extreme environmental standards such as above and beyond IMO requirements.

Innovation has always been the core of Scienco/FAST®. Decades of experience has taught us that our pre-engineered, modular components provide good installations aboard vessels and platforms of all types. The company continues to expand its product offering to include other transfer, treatment devices, and components for a multitude of applications, nitrogen reduction, oil/water separators, grease removal, membranes, renovations, aeration and mixing, biological tablets, and various other screening/filtration devices.

As world leaders in the on-site wastewater treatment markets, Bio-Microbics® and Scienco/FAST® provide advanced technology for wastewater, stormwater, and water treatment industries. From its diverse past, Scienco/FAST® has been a part of such influential companies as Morton Salt and Smith & Loveless, Inc.

Internationally recognized for quality products and top-notch field services, Scienco/FAST® is a manufacturer specializing in marine sewage devices, biological tablets, and other industrial technologies. The origins of SCIENCO® & FAST® can be traced back to the 1940′s in St. Louis, MO.
