Alternative Onsite Sewage Systems
Commonly Used Wastewater Treatment Systems
Alternative Onsite Sewage Systems (AOSS) are specifically designed for your property and needs. There are a variety of different treatments that can be added to your system to ensure proper treatment of wastewater. Below are some of the most common treatment systems used within our service area. Greenway is not affiliated with an specific treatment unit manufacturer and will discuss the treatment unit options with the owner/client/builder prior to the septic design.
MicroFAST®
The BioMicrobics MicroFAST® septic system is an advanced, aerobic treatment unit (ATU) that enhances conventional septic tanks using Fixed Activated Sludge Treatment (FAST) technology. It forces air into a submerged, honeycombed media, fostering beneficial bacteria to quickly break down wastewater organic matter and nutrients for high-quality effluent.
AdvanTex
The AdvanTex Treatment System, designed by Orenco Systems, is a compact, textile-based secondary aerobic wastewater treatment system for residential and commercial use. It utilizes recirculating technology to treat sewage better than standard systems, making it ideal for small sites, poor soil, or high-nutrient areas. Key benefits include low power use, minimal odors, and high-quality effluent.
FujiClean
FujiClean septic systems are advanced, compact, one-tank aerobic treatment units (ATUs) designed to treat residential wastewater to high standards, often for up to 1,000 gallons per day. They use a “Jokaso” technology combining anaerobic and aerobic chambers with fixed-film media to treat waste before discharging to a drainfield.
