MBBR (Moving Bed Biofilm Reactor) filter bio media work by providing a surface for the growth of beneficial microorganisms that form a biofilm. Here's how the MBBR process with bio media works:
During the extrusion process, the screw is often exposed to working conditions such as high torque, high temperature, high speed, and high pressure. Sometimes it is also exposed to harsh conditions such as high wear and corrosion.
