This document discusses the production of cassava starch in Colombia. It evaluates the sedimentation process used in channels to separate the starch. Two main components were analyzed: the change in concentration of slurry entering the settling zone, and the particle size distribution within the zone. It was found that the slurry concentration during processing was typically between 0.1-6%, and discrete particles settled efficiently. Larger particles over 10 micrometers were retained in the first 104 meters of the channel, while particles from 6.7-8.8 micrometers were discharged and caused environmental issues.
