followed by Zn (77.5%), Fe (73.16%), Mn (3.48%), and Mg (2.4%). These trace elements were removed by anaerobes to enhance the UASR process stability and VFAs degradation. As such, these
However, due to the complexity in rotary machinery systems and the multiplicity of parts, the probability of failure is greatly increased. Among all the components in rotating machines, rolling element bearings (REBs) are used in a majority of them. Bearings facilitate the movement of components ...
