AdvanTex Residential Wastewater Treatment System

Advanced Treatment Systems

Orenco’s AdvanTex® Treatment Systems are the ideal solution for environmentally sustainable treatment of residential wastewater flows.

Advanced Treatment Systems

In advanced or secondary wastewater treatment, septic tank effluent is purified to a level suitable for subsurface drip irrigation. Media filter technology, in use for more than 100 years, is a science-based technology...the gold standard for advanced treatment.

In media filter systems, effluent trickles through a moist, porous media. Microorganisms growing in the media remove impurities from the effluent. Compared with advanced treatment systems that blow air into liquid or use membranes, packed bed systems use less electricity, require less maintenance, and are much less prone to upsets from the ups and downs of day-to-day life.

For advanced treatment, Orenco's flagship product is the AdvanTex Treatment System. Using Orenco's textile filter technology, AdvanTex can reduce BOD and TSS (two measures of the strength of pollution) by up to 98%. AdvanTex can also reduce nitrogen (a nutrient in wastewater that must be controlled in some areas) by up to 70%. Learn more about BOD and TSS. And AdvanTex can be used with an Orenco AXUV Disinfection Unit to kill nearly all bacteria and viruses (also a requirement in some areas).

The effluent that comes out of an AdvanTex System is so clean and odorless that, in many cases, it can be used for drip irrigation of landscaping.  Many jurisdictions around the United States allow the use of drip irrigation for the dispersal of effluent.  Orenco's Shallow Pressurized Dispersal Systems (SPDSs) offer a simpler, less expensive way to to disperse of the highly treated effluent.

Since 2000, more than 25,000 AdvanTex filters have been installed throughout North America and in more than a dozen countries around the world.

AdvanTex has undergone more -- and more rigorous -- third-party field trials than any other residential treatment system on the market. And we have the Performance Summaries to prove it:

AdvanTex AX-RT

Orenco’s AdvanTex AX-RT is a completely pre-packaged, “plug & play” residential wastewater treatment system. Same great performance as the AX20, but all the interior components are assembled and adjusted at the factory, so customers save on installation costs. There are also fewer working parts, so customers save on equipment costs. Learn more about AdvanTex AX-RT
