Eljen Geotextile Sand Filter (GSF®)

Eljen logoAffordable Septic Solutions is pleased to announce that we now offer the Eljen Geotextile Sand Filter (GSF®) in Virginia as an affordable, low-maintenance alternative to suspended growth ATU’s and media filter advanced treatment systems. (See an installation example.) The Eljen GSF® is currently approved in Virginia as a secondary treatment device.  Under the recently adopted Emergency Regulations for Alternative Onsite Sewage Systems, the GSF can be designed with a reduced footprint of 50%!  The GSF has been used throughout New England and other States with a proven track record for over 25 years and received 3rd party testing at the Massachusetts Alternative Septic System Test Center (MASSTC) in accordance with NSF/ANSI Standard 40 protocol for a 32-week period with results that show CBOD and TSS results well below 10 mg/l and fecal coliform removal of 90 – 99% for gravity systems and 98.41 – 99.99% for time pressure and demand dosed systems.

The Eljen GSF is a passive advanced treatment system that treats wastewater at the disposal site with a patented two-stage Bio-Matt™.  The GSF is constructed of recycled materials forming a lightweight, easy to handle module that can be installed in series with other modules on a layer of specified sand either in a trench, bed, or mound configuration. Depending upon the site and soil limitations of a given installation site, the Eljen GSF can be installed below grade for gravity disposal with no pumps or aerators required. For shallow-placed or above ground installations, a pump station may be required.
