PASSIVE TREATMENT SYSTEMS AND RUCK “A” UNITS
Nitrogen & Phosphorus Removal & Prefiltering Leach Field
RUCK SYSTEMS® were introduced in 1977. RUCK denitrification (nitrogen removal) treatment systems service domestic dwellings, commercial and industrial sites. Ruck A units were developed to increase the surface area at the biomat interface and/or to prefilter prior to the Infiltration Surface in sand filters and leach fields.
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 long-term
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 42 INCH 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 long-term infiltration capacity.
RUCK SYSTEMS® is actively pursuing product research and development in on-site systems. The design and installation manual must be used in conjunction with the current code.
We are available to assist you with specific design problems. We can review your designs prior to submission for approval. Ruck A Units can be purchased via phone, fax or by writing to us and will be shipped by UPS COD, or may be picked up at our plant in Connecticut.
