Abstract
PURPOSE: To carry out good flocculation independently of the amount of added flocculants, by adding to the muddy water the anionic polyglucose electrolyte and the water-soluble salt of chitin hydrolyzate.
CONSTITUTION: Either the anionic polyglucose electrolyte (for example, a sodium- salt of carboxymethylcellulose) or the water-soluble salt of chitin hydrolyzate (for example, an acetate), is selected and is added to the muddy water as the powder style or as the about 0.01W2% aqueous solution, to the extent of about 100W 5000ppm against the amount of muddy water. Then, in accordance with necessity, after or while forcibly agitating the muddy water, another flocculant is added as about 0.01W2% aqueous solution. As a result, the muddy constituent of the muddy water quickly forms the coarse flocs and settles. Besides, it is desirable to specify the ratio of amounts of added flocculants, that is chitin hydrolyzate/anionic polyglucose electrolyte to be about 0.5W1.2 by weight.
