Phase separation of salt dispersions of clay with polyacrylamide flocculants

Phase separation of salt dispersions of clay with polyacrylamide flocculants Effect of polyacrylamide (co)polymers on the properties and structure of floccules formed in the course of phase separation of a salt dispersion of clay was studied. It was shown that, with a binary system of unlike-charged copolymers, a sediment with high density and water-yielding capacity is formed, which is necessary for the effective phase separation. The subsequent squeezing of the flocculated sediment to remove water leads to a local increase in the concentration of polymers in the solid phase, which raises the plastic strength of the sediment and improves the granulation conditions.
