Abstract
The precipitation and removal of suspended organic containing particles, such as starch, and other suspended solids from a given solution can be accomplished by the addition of multivalent metal ions and their complexes in order to form metal ion/organic particle complexes and the addition of a flocculating agent to flocculate the metal ion/organic particle complexes into insoluble particles capable of removal by conventional technology.
