Abstract
PURPOSE: To obtain a water treating agent that shows superior dehydration to sludge, etc., by adding and stirring sawdust or chaff to a water-soluble vinyl monomer and by performing graphite polymerization.
CONSTITUTION: A solution of about 20W90% in concentration of a water-soluble vinyl monomer such as methyl chloride salt of dimethyl amino ethyl methacrylate is set at a liquid temperature of about 20W80°C. Into this solution, sawdust or chaff is mixed and stirred and the mixture is left as it is, so that a graphite polymer can be obtained by the radical generating function of the sawdust or chaff. Using this polymer as a dehydrating agent for sludge, etc., can increase a dehydrating and filtering speeds, etc., by a small quantity of the additive in comparison with those when a high molecular condensating agent and sawdust, etc., are used separately.
