The AdvanTex System is simple and inexpensive to operate. Click Here it see a brief video on how it works.

Sewage goes into the Septic Tank (1) moving the tanks contents slowly along.
Seperation - Digestion - Clarification
Gravity seperates solids from natural digestion and clarifies the effluent as it slowly moves forward into the Recirculation tank. (4)
Recirculation - Treatment
Every 30 minutes for 30 seconds, 24/7, effluent is sprayed over the AdvanTex filter and returns in the Recire Tank (3). Calmly. No mixing. No bubbling, churning mass. No noise. No smell.
Excess clear filtrate overflows directly to pump basin (5) for discharge.
Packed Bed Filters (AdvanTex)

Simple and Inexpensive to Operate.
Process - Packed Bed Trickling Filter.
Continuous natural flow through.
AdvanTex - unique, but not new.

AdvanTex AX20 was designed specifically for individual residential use. It uses 15 year life cycle well pumps to recirculate clarified effluent over the AdvanTex filter, without mixing or aeration. This intermittant pumping uses only about $6.00 of electricity per month.

For primary treatment, AdvanTex harnesses a simple, passive, and time proven septic tank which uses no power.

A standard sized septic tank provides natural solids digestion and clarified effluent. The AdvanTex treatment system in it exposes small doses of effluent to a lot of ambient air. Tank pumping interval is typical for septic tanks at 8-10 years. Effluent quality is consistently high.

This naturally occurring biological process is extremely stable. It is designed for, and so it is ideal for varying residential flows.

AdvanTex is virtually unaffected by periods of inactivity Startup and Stabilization is immediate. It is impossible for AdvanTex to pass untreated solids to a disposal field.

Documentary: No activated sludge is created so no digester is required. Pumping intervals are extended from every few months to every few years. Because a packed bed trickling filter is virtually unaffected by varying flows, it is inexpensive to operate. One operator says, "In a nutshell... it (AdvanTex) is the best thing out there as far as effluent quality, which equals life span of the disposal (drip) system. A bonus is that O and M are minimal, reducing (operating) costs."
Aerobic Treatment

Complex and Operationally Expensive
Process - Extended Aeration.
Continuous mechanical agitation and acration.
ATUs - Generic Aerobic Treatment Units

Small ATUs are basically a residential adaptation of a municipal sewer treatment plant design originally created to treat hundreds of thousands of gallons a day.. Residential ATUs use short life cycle pumps ($200-300 each) for aggressive mechanical mixing and aeration. They run constantly, requiring a lot of electricity making them expensive to operate and to repair.

For primary treatment, ATUs use a complex operationally expensive mechanical process, forcing a small amount of air through a lot of sewage. Activated sludge is created.

ATUs generally use undersized trash tanks and substitute tank pumping for solids digestion. Clarification requires a seperate compartment or tank. Tank pumping intervals of 1-3 years are common. ($350 each) Effluent quality is often inconsistent and poor. And if you don't pump, it costs BIG$$$

This forced mechanical process is unstable and needs constant manipulation (which it doesn't get) to produce high quality effluent. Varying flows cause upsets making them less than ideal for residential use.

After periods of inactivity, it takes 3 or more weeks for a system to start up and stabilization. During this time, there is little or no treatment. This causes upsets, a condition in which ATUs spew out unclarified activated sludge that can plug a disposal field and cause costly major repairs.

Documentary: The process creates activated sludge that cannot be consumed without a digester. This means pumping the unit often, making it expensive to operate. The same operator says "They (ATUs) are affected by surges or deprivation of flow... much more than packed bed filters. I know the ATU manufacturers say that the effluent quality... in consistent, but those of us who have operated municipal systems with daily permit limits, know better."
It seems pretty simple, doesn't it?

Well, It Is! AdvanTex AX20 was specifically designed for individual residential use. It is not an adaptation of something designed for an entirely different purpose.

Check out the process and the product comparison and ask yourself why in the world would anyone want to complicate it with something that doesn't work as well.
