Air Dissolution in an Air Saturator of a Dissolved Air Flotation (DAF) System
Good day guys
Currently, I am working on air dissolution in an air saturator of a DAF system. We all know that increasing recycle ratio and saturator pressure are two options to increase the mass concentration of the air. This is mentioned in existing literature of DAF systems.
However, as we increase the recycle ratio, we decrease the hydraulic retention time in saturation tank which finally leads to a less air dissolution. This is against what literature said. I am a bit confused!!
