Wastewater Treatment Solutions
A3 designs, manufactures and commissions wastewater treatment plants including MBR, SBR, and CAS systems for the North and South American markets.
Wastewater Plants & Equipment
Since 2000, A3’s MaxFlow plate membranes have been treating wastewater in projects across North America and other regions worldwide.
A3-USA supplies complete wastewater treatment plants in the North American and South American markets. We build our patented membrane modules near Jacksonville, NC. We’ve supplied plants for municipalities, universities, breweries, developers, industries, and casinos.
- WWTP plants and membrane modules are built here in the United States.
Made in the USA
Wasterwater Treatment Plants
A3-USA designs and manufactures membrane bioreactor (MBR), sequencing batch reactor (SBR), and conventional activated sludge (CAS) wastewater treatment plants. We are the only MBR plant integrator who manufactures the complete plant, including the membrane modules.
