Armor ABJ is a leading manufacturer of stainless-steel decanters, a key piece of sequencing batch reactors (SBR) wastewater treatment systems

Our decanters are US-designed, tested, and manufactured to provide reliable, maintenance-free, evenly distributed decanting.  Armor ABJ engineers conduct 3D modeling and structural analysis to ensure proper water flow rates, load tolerances, and uniform lowering across the length of the weir.  Our ISO 9001:2015 registered, 315,000 square foot facility is conveniently located in the Midwest, enabling quicker delivery and customer support. 

We offer a full range of SBR wastewater stainless steel, single-span decanter sizes from 1.5′ to 40′, and also provides dual decanters for larger projects, such as two 25′ decanters for 50′ applications. ABJ decanters provide uniform vertical weir descent while maximizing the exclusion of scum and floatables through the use of a weir float-wiper system. Armor ABJ passivates all decanters in a way that extends material life while providing environmental best practices.

We are process-driven and continuously looking to provide new and improved technologies in wastewater treatment.
Armor ABJ is proud to provide its decanter technologies that help improve water quality for communities across North America.
