METHOD FOR IMPROVING THE UTILIZATION OF POLYELECTROLYTES IN DEWATERING AQUEOUS SUSPENSIONS

METHOD FOR IMPROVING THE UTILIZATION OF POLYELECTROLYTES IN DEWATERING AQUEOUS SUSPENSIONS

This invention relates to a method for improving the utilization of water-soluble, high molecular weight (molecular weight above about 1,000,000) polyelectrolytes in the dewatering of aqueous suspensions. By aging a mixture of the polyelectrolyte and water for a period of at least 6 hours to form an...

description This invention relates to a method for improving the utilization of water-soluble, high molecular weight (molecular weight above about 1,000,000) polyelectrolytes in the dewatering of aqueous suspensions. By aging a mixture of the polyelectrolyte and water for a period of at least 6 hours to form an aged solution the amount of polyelectrolyte required to effectively dewater an aqueous suspension may be reduced to as little as 50% of the amount required when an unaged solution is used.
