The AFS extended treatment system constructed with Orenco Systems®, Inc AdvanTex® AX20 packed bed filter is the ideal solution where extended treatment of septic tank effluent is required or desired. AdvanTex® AX20 Extended Treatment Systems use time proven technology to reduce BOD (Biochemical Oxygen Demand) and TSS (Total Suspended Solids) to extraordinarily low levels, allowing installation into locations that are not permittable with conventional systems. The AdvanTex® treatment pod contains extremely effective textile media for treatment and is roughly 21 ft2 in size, making it ideal for small or difficult lots. AdvanTex® AX20 Extended Treatment Systems can be used in locations that require denitrification (Mode 3). AdvanTex® AX20 Extended Treatment Systems can mean the difference in approved or disapproved septic permits.
