Eljen GSF, an efficient and passive solution
ELJEN GSF has been used in hundreds of thousands of residential and commercial sites across North America. It is one of the few technologies tested in tough winter cold conditions still providing superior treatment performances. This compatibility with our Canadian climate and Eljen GSF’s unique characteristics of simplicity, passiveness, performance and minimal need for maintenance make it a very wise choice.
Avantages
- One of the most affordable technology available
- 100% passive, advanced combined treatment and dispersal system
- Tested for Canadian cold climate
- No Sand Mantle Required
- No mechanical parts, no energy consumption
- Over 150 000 systems installed
Technical Specificities
Reduction of pollution from Wastewater is achieved from the combined action of a two-step biofiltration process. The first step is taking place within the ELJEN GSF modules while the second step takes place in the compact Specified Sand layer under and on the side of the ELJEN modules. Treated effluent is either discharged in the native soil directly under the Specified Sand layer for subsurface infiltration or, depending on local regulation, can be collected in a watertight liner for surface discharge or further treatment (depending on the sensitivity of the receiving environment).
Functionment
The first treatment step takes place within the patented ELJEN GSF modules. Each module consists in a geotextile biofilter configured in multiple successive zones of effluent collection and passive aeration chambers all alternating in an accordeon shape. Alternating zones are achieved using cuspaded recycled plastic sheets. This unique and efficient configuration results in a fully passive aerobic biofilter displaying extremely high surface of geotextile for bacterial development. These bacteria are responsible for the degradation of the pollutants from the wastewater as it filters through the module. Each ELJEN GSF module is only 600 mm (24 in) wide by 1200 mm (48 in) long and 175 mm (7 in) thick. Each weights about 5 kg (+/- 10 lb) and are installed in rows directly over a layer of Specified Sand (ASTM-C33 concrete sand).
The second treatment step takes place in a thin layer of Specified sand of only 150 mm (6 in) located on the sides and under each module. Treated effluent filtering from the ELJEN GSF units disperses horizontally and vertical in this sand layer where it can later slowly get absorbed in the native soil. This sand layer protects the native soil from compaction and preserves its natural infiltration capabilities by assuring a uniform dispersal of the highly treated effluent. This maximizes the life expectancy of the system and greatly reduces (many times avoids) risk of clogging.
In most applications, treated effluent from the ELJEN GSF System is infiltrated in natural soil directly under the Specified sand layer making it a compact combined treatment and dispersal system.
With a life expectancy often way over 20 years, the ELJEN GSF will most likely be you last septic system ever. Once your ELJEN GSF system will reach the end of its life, since you have protected your natural soil infiltration capacity, only the modules will need replacement making the ELJEN GSF a truly permanent solution.
