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.

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.

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.
