Abstract
THE INVENTION IS A METHOD FOR CLARIFYING, DEWATERING OR IMPROVING RETENTION AND DRAINAGE OF INDUSTRIAL WASTE WATER OR PAPER FURNISH FURNISM WITH AN EFFECTIVE AMOUNT OF AT LEAST ONE DISPERSION OF A WATER SOLUBLE CATIONIC POLYMER FLOCCULANT WHEREIN THE IMPROVEMENT COMPRISES THE ADDITION OF SAID POLYMER WHICH HAS A CONCENTRATION OF AT LEAST TWENTY FIVE PERCENT TO SAID WASTE WATER OR PAPER FURNISH. THE INDUSTRIAL WASTE IS PREFERABLY FOOD PROCESSING WASTE WATER, OILY WASTE WATER, PAPER MILL WASTE WATER AND INORGANIC CONTAMINATED WASTE WATER. THE PAPER FURNISH MAY BE AN AQUEOUS CELLULOSIC SUSPENSION.
