ABSTRACT:
A water clarification process wherein solids are separated by filtration through a porous septum utilizes as a filter precoat a coating of keratin-composition in the form of particles wherein at least 75 weight percent of the particles have a particle size no greater than 2.0 mm. In preferred embodiment, the material to be filtered is first treated with a combination of an organic polymeric flocculant and an organic polymer coagulant.
