Abstract

PURPOSE: To solidify stably suspension without consuming a large amount of water and spending much time and labor by adding powders composed of a mixture of cement or calcium and powdery macromolecular coagulant to the suspension.
CONSTITUTION: Powders composed of a mixture of cement or calcium and powdery macromolecular coagulant are added to suspension in water treatment. The mixture is stirred. Cement or calcium is dispersed into the suspension. Calcium including that contained in the cement act on interfacial potential of suspended matter. The suspended matters form flocks by weak cohesive force. When the stirring is continued, the macromolecular coagulant is easily dissolved without coagulation in a fisheye form and is converted to coarse flock having strong physical strength, wherein a nucleus is composed of cement or calcium hydroxide. The flock is completely separated from water and precipitated. The precipitated sludge has good dehydrating property and is easily solidified.
