Abstract
Methods for aggregating suspended solid particles in an aqueous medium involving mixing the aqueous medium with an effective amount of a flocculant to aggregate the solid particles to form aggregated solid particles, and optionally separating the aggregated solid particles from the aqueous medium. The flocculant is obtained from animal blood. The pH of the aqueous medium may be adjusted to a pH of about 4.5 to about 5.7 by the addition of at least one acid or acidic buffer. The temperature of the aqueous medium may be adjusted to a temperature range of about 10° to about 50° C.
