METHOD OF IMPROVING DEHYDRATING PROPERTY OF BIOLOGICAL PURIFYING SLUDGE

Document Type and Number:

Japanese Patent JPS63283800

Kind Code:

A

Abstract:

The ease with which biological sewage sludge, particularly digested sludge, can be dewatered is improved if the sewage sludge is treated with hydrolytic enzymes such as carbohydrases (amylases, cellulases), proteases, glycoproteinases and/or lipases, followed by the addition of a synthetic flocculant, particularly a cationic polyelectrolyte.
