REX: A Familiar Name in Water & Wastewater Treatment

In the world of environmental and water treatment, the term "REX" carries significant weight. It stands for "Rotary Equipment eXchanger," a technology commonly used in biological wastewater treatment systems. This technology, pioneered by USFilter/Envirex, revolutionized the industry by introducing a highly efficient and reliable method for handling and processing wastewater.

What is a REX System?

A REX system is essentially a rotating biological contactor (RBC). It consists of a series of rotating discs, typically made of high-density polyethylene (HDPE), submerged in wastewater. The discs are partially immersed, allowing for biofilm formation on their surfaces. As the discs rotate, the attached biofilm is exposed to both air and wastewater, facilitating the biological breakdown of organic matter.
