AdvanTex® Treatment Systems are the ideal solution for secondary treatment of residential wastewater flows. Orenco’s patented* AdvanTex systems consistently produce such good effluent — e.g., BOD and TSS in the 10/10 mg/L range, even under peak flow conditions — that homeowners often have them installed with subsurface drip systems for landscape irrigation.
