Saff Media

Saff media, Most plants until the last century had its attached growth process using structured packing and some fluidized media of MOC in PP, HDPE or PE. These media were derived from chemical process industries using it in the scrubbers as tower packing. In scrubbers of chemical process, the emphasis was on low pressure drop but maximize the surface area for a given volume, for improved efficiency and lowering energy requirement. However, in a biological process, increase in surface area although increases pressure drop, MOC being heavier than water, such as the Scogen® BioSwirl, is found more suitable for fluidizing in the reactor to offer fully wetted surface.
