This article showcases several innovative Advanced Treatment Units designed to improve efficiency, reduce environmental impact and meet stricter regulations. Options include units that offer space-saving designs, utilize prefabricated technology, cater to situations requiring a downstream pump or are designed for properties with challenging soil conditions.

Eljen Geotextile Sand Filter
The Eljen GSF, or Geotextile Sand Filter system, is designed to provide treatment and dispersal in the same footprint with easy installation and minimal maintenance. It is used for commercial and residential applications. Utilizing a two-stage pretreatment process, the geotextile modules apply filtered septic tank effluent to the soil, increasing the soil’s ability to accept effluent and increase the long-term acceptance rate. Its design provides increased surface area for biological treatment that greatly exceeds the module’s absorption area. Open-air channels within the module support aerobic bacterial growth on the module’s geotextile fabric interface, surpassing the surface area required for traditional absorption systems. The system is tested and certified by NSF to NSF/ANSI Standard 40.

Orenco Systems AdvanTex AX20-RTUV Treatment System
The AdvanTex AX20-RTUV Treatment System from Orenco Systems is a self-contained module that treats typical septic tank effluent to better than secondary standards, with nitrogen reduction and ultraviolet disinfection. It is especially suited for small sites with poor soils or that require shallow burial. It helps protect surface waters and aquifers and is an effective solution for areas that have strict discharge limits, according to the maker. It is installed following a septic tank equipped with Biotube Effluent Filters. The unit eliminates the need for separate recirculation, treatment, discharge and disinfection tanks and basins and reduces the number of risers and lids needed in the treatment train.
