Abstract
Abstract RAPID FLOCCULATION OF PARTICLES CONTAINED WITHIN FLUIDS, SUCH AS SOLIDS DISSOLVED IN WATER, IS CAUSED BY PASSING THE FLUID FIRST THROUGH AN ELECTROSTATIC TREATER AND SUBSEQUENTLY THROUGH AN ELECTROLYTIC TREATER SO THAT THE FLUID EXPOSED TO AN ELECTROSTATIC FIELD IN THE FIRST TREATER IS THEN SUBJECTED TO ELECTROLYSIS IN THE SECOND TREATER. NO PLATING OUT OF PARTICLES ON THE ELECTRODES OF THE SECOND TREATER OCCURS BECAUSE OF THE RESIDUAL EFFECTS ON THE FLUID OF THE ELECTROSTATIC TREATER. ALTERNATIVE EMBODIMENTS OF THE ELECTROLYTIC TREATER ARE ADAPTED FOR PIPELINE CONNECTION AND SETTLING POND FLOTATION RESPECTIVELY.
