Treatment Method. Oils and Fats Recovery. The oils and fats recovery system adopted obviously depends on the local circumstances. Typically, the first stage of pretreatment is the use of a physical process to recover the free oils and fats. The most commonly used physical separation process for the removal of free oils and fats are fat traps, tilted-plate separators, and dissolved air flotation units. In addition, centrifuge and electroflotation systems are occasionally used (73). 

In addition to the aforementioned techniques, most commonly used for the characterization of fibers, fiber assemblies, and fabrics in terms of their wetting behavior or surface tension, there are also other methods available the determination of the contact angle from the equilibrium meniscus near a floating fiber [80], the reflection method initially developed by Jones and Porter [137] (reviewed in Refs. 1 and 32), the tilted fiber or rotating stage technique [138,139], and the solidification front method (recently reviewed in Ref. 140).
