Septic media filters:
This article series discusses the design and use of various types of septic media filter systems.
Media filter septic systems use a conventional septic
tank followed by any of several methods to further filter and treat septic effluent before it is discharged to
the soil, soil surface, or waterway.
When using a septic media filter system, effluent treatment is by both actual filtration and ultimately by a biochemical process as the
filter "matures" and includes its own biomass. Both natural media filter septic systems (such as sand, gravel, or peat)
and synthetic media filter septic systems (foam cubes, glass, slag) are used, and both single-pass and effluent
recycling systems may be employed.
These different septic media filter types are explained here. We include a list
of product sources for various types of septic filters.

Septic media filters using textiles
Geotextiles are often used in septic effluent media filter systems; they can provide a large surface area and high
water volume retention.
Fabric media is cut into squares and placed into a container, or hung in curtains in a container.
Textile filters operate in a recirculating mode similar to that discussed above, but offer this advantage over
sand and peat media: the larger effective surface area of the synthetic textile permits a much higher loading rate in
gallons per square (or cubic) foot, thus permitting the media system to be designed into a physically smaller package.
Septic media filters using open celled foam cubes
Two-inch open-celled polyurethane cubes are placed into a container to form a packaged or "pre-fab" septic media
filter system which is used in either single pass or recirculating effluent mode.
Packaged foam cube septic effluent
(wastewater) treatment systems may be placed
entirely above ground (but of course will not work in an area of hard freezing climate).
Septic effluent is passed
into the foam filter in small doses (1/10 gallon to 1 gallon per cubic foot per dose) using spray nozzles which
dose the system from its top. An advantage of this system is its easy maintenance as the (clog prone) top few inches of
foam cubes are easily removed and replaced.
Septic Media Filter System Capacity
A typical media filter system is designed using a flow of 50 to 65 gallons per day per occupant of the
building served by the system. This number, cited by several authors including Jantrania, Minnis, and Kahn, Allen, and Jones,
is less than other total wastewater load estimates but is considered by these authors to be realistic and is consistent with
a number of studies performed on typical wastewater flow rates and quantities.
Septic Media Filter Maintenance
The system design maintenance required of the media filter system as well as its operating characteristics vary considerably
depending on the media selected, with open cell foam and textiles providing higher gallons per day loading ability than peat and other media.
"Maintenance" in this case will refer to inspection of the media bed to determine when the media needs to be
cleaned or replaced. Some systems, such as sand filter beds, are raked or agitated rather than replaced, but ultimately
all filter systems will become clogged and face media replacement.
Septic filter media maintenance and replacement cost should be factored into
estimates of alternative septic system costs when comparing alternative septic system designs.

I have been unable to find info on the Care & Maintenance of this system. I know, that at one point, it was required in my area, but that is not the case now. I've lived in this house for 20 years and had only minor problems.
I'm now selling the house and would like to have some kind of "Care & Maintenance" info for the new owner. Can you help me with this? - anonymous [by private email]
Reply: where to get Ruck® septic system information & design or maintenance help
Sure; here are some resources for Ruck septic systems:
Costa, Joseph E., George Heufelder, Sean Foss, N. P. Millham, and B. L. Howes. "Nitrogen removal efficiencies of three alternative septic system technologies and a conventional septic system." Environment Cape Cod 5, no. 1 (2002): 15-24. Retieved 2015/11/23, original source: http://buzzardsbay.org/etistuff/results/costaenvccarticle2.pdf
Abstract: At a septic system testing center, conventional design onsite wastewater disposal (“Title 5”) systems, were
found to have a net nitrogen removal capability of 21-25% when data from the base of the Soil Absorption System
(SAS) was considered, after accounting for an assumed precipitation recharge dilution of 10%. This reduction
occurs principally in the soil absorption system, a component that is often overlooked in comparative studies.
Nitrogen losses in the septic tank ranged from 1% to 3%. Successful proprietary nitrogen removal systems tested
like the Waterloo Biofilter trickling filter and MicroFAST Model 0.5 systems had a net nitrogen removal capability
of 60% and 55% respectively, thus discharging slightly more than half the nitrogen discharged by a conventional
system. In these technologies, most nitrogen reduction occurred prior to discharge to the SAS.
The recirculating sand filter (RSF) designs tested removed approximately 41% of influent nitrogen, but we
did not examine SAS losses, and overall system performance may be slightly better than this with a SAS installed.
Without the SAS, the RSFs tested discharged 25% less nitrogen to groundwater than the Title 5 systems.
Conventional septic systems with a Geoflow Wasteflow Drip Line system in the SAS removed 42% of influent
nitrogen overall, showing that the performance of a SAS can be improved by injecting discharge near the topsoil,
to allow nitrogen uptake by grass and other vegetation.
This Drip Line design, combined with another septic tank
technology could result in very high overall system nitrogen removal rates. One experimental design (ECORUCK)
had a nitrogen removal ability less than a conventional system and was withdrawn after one year of testing.

Abstract excerpted from the document introdction:
The RUCK ACCORDION system is a cost effective, treatment based upgrade from conventional stone and other leach field systems. The ACCORDION system is based on proven enhancements. Evapotranspiration, oxygen transfer, biodegradation, soil treatment and longterm operation are accomplished by using biotextile prefiltration and controlled soil loading.
Biofabric technology is based on 25 years of published research work and field experience.
Multiple vertical infiltrating surfaces of biofabric and sand is provided per square foot of trench bottom area. ACCORDIONS are installed on top of 6” of sand by stretching the unit to specified length in 42INCH wide trench and filling with sand. The accordion modules are interconnected using PVC pipes.
The primary biomat layer forms within the biofabric. The ACCORDION leach field is sized for the longterm acceptance rate (LTAR). RUCK ACCORDION leach fields are designed to operate indefinitely, not for a halflife of 25 years as with other systems. The soil directly below the sand and accordion module develops only a minor secondary biomat layer. The result is a greater longterm infiltration capacity.

Innovative RUCK Systems, Inc. (IRUCKS) designs alternative innovative on-site septic systems called RUCK® systems. The RUCK® wastewater treatment system is a proven cost-effective innovative septic system that uses a proprietary design to obtain significant removal of nitrogen from wastewater.
There are two different RUCK® system designs – a Traditional RUCK® system for flows less than 2000 gallons per day and a RUCK® CFT System for flows greater than 2,000 gallons per day, but less than 10,000 gallons per day.
RUCK® systems generally include the addition of supplementary components to a traditional soil absorption system. Treatment occurs through the creation of a series of alternating environments in which bacteria first nitrify wastewater and then perform denitrification.
Design of a RUCK® system is done on an individual basis.
Plans and specifications are prepared by a consulting engineer trained in RUCK ® system design.
In Massachusetts the traditional RUCK® System has been issued a General Certificate by the Department of Environmental Protection as an innovative and alternative septic system. RUCK® CFT Systems has been issued Piloting Approval by the Department. Contact the designers for the status in other states.
I'd appreciate seeing details of your system and photos of any components you can access.
Thank you Very Much, but I cant see Any Components without digging.
I know there's an Extraction Pump that I had to replace because someone took a shortcut by installing a 1 1/2" - 2" fitting in order to buy a cheaper pump! And I had to dig up the area where the pipe goes into the house because it was the wrong Schedule pipe! Grrrrr, What some People will do to save about a hundred bucks huh?
The good news is that besides getting it pumped every 2-3 years, these are the only problems I've had.- Anon
I've read a Costa (2002) study about one Ruck system design that was dropped (ECORUCK) from the study because of its poor reduction of nitrogen. Is your Ruck septic system currently permitted in new construction where you live or is your system "grandfathered" in?
From what I heard, It was So Expensive that they had to stop requiring it. Heard it cost $25,000 in My house! Never heard anything about not being able to have it, or getting Grandfathered.
It's All Septic here. I see lawns getting dug up all the time, but mine is just fine.
The reason for the RUCK is to lessen the Nitrogen, and it didn't work as well as expected, but better than regular systems. Again, I think it was mainly Costs
