The ELJEN GSF SYSTEM
The Eljen GSF is primarily used for leachfields where advanced
treatment is needed to meet environmental needs. It is used in
bed and trench designs.
The Eljen GSF A42 (four
feet long by two feet wide by seven inches high) requires a longer,
thinner trench, which can be a benefit where site restraints and
hydraulic needs are a prime consideration.
The Eljen GSF leachfield offer the following advantages:
Provides advanced treatment in 50 percent less space than aggregate
systems.
Proven reliable performance eliminates the need for complicated
maintenance and maintenance contracts. and will automatically
Smaller size and streamlined design significantly reduces overall
system cost.
Long term leaching capacity is two to three times that of similar
systems.
The only system that pre-treats leachfield effluent with a patented
two-stage Bio-Matt filtration process.
Made from lightweight recycled material, the GSF leachfield is
engineered for superior strength.
The Eljen In-Drain, with its
prefabricated modular units comprised of geotextile fabric and
cuspated spacer cores, provides an alternative to conventional
stone and pipe or chamber leaching systems.
Substantial effluent pretreatment occurs within the biomat which
develops on the 100 square feet of geotextile fabric and the 400
square feet of cuspated core surface area in each 12-square foot
Type B In-Drain unit.
This internal passive pretreatment protects
both the soil long-term acceptance rate (LTAR) and groundwater
quality while providing reduced system trench length or leach
bed footprint. At 7 inches thick, In-Drains provide the lowest
product profile, thus reducing system finished grade.
Benefits of the In-Drain include:
· Pretreatment of effluent via a two-stage biomat
· Greater long-term leaching capacity maintained
· Smaller area required than conventional systems
· Has lower site impact and requires less off-site fill
· Fabricated of lightweight recycled materials
· Excellent documented long-term track record
· 10-year warranty.
Laboratory analysis of treated effluent extracted from below
the In-Drains has confirmed Eljen's claims of substantial effluent
pretreatment (over 50% BOD reduction) provided by the biomat at
the geotextile fabric and cuspated core surfaces.
In-Drains installed
in a 6-inch layer of washed concrete sand can provide secondary
treatment for typical septic tank effluent
In-Drain passive pretreatment systems require only standard periodic
inspection and pumping of the septic tank.
