Title:
FLOCCULANT INJECTION AMOUNT DETERMINING APPARATUS
Document Type and Number:
Japanese Patent JP3967462
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide the subject apparatus rapidly corresponding to the alteration of properties of supplied sludge to automatically determine the optimum injection amt. of a flocculant.
SOLUTION: A flocculant injection amt. determining apparatus is an apparatus for determining the injection amt. of a flocculant to a flocculating and mixing tank for flocculating sludge and equipped with a measuring tank 1, a separated soln. supply part 2 for supplying a dehydrated and separated soln. obtained by dehydrating flocculated sludge to the measuring tank in a constant flow rate, a drainage part 5 keeping the liquid amt. in the measuring tank constant, a measuring part 4 measuring the amt. of floc present in the dehydrated and separated soln. supplied to the measuring tank and a control means determining the injection amt. of the flocculant minimizing the amt. of floc based on the measured data of the amt. of flock by the measuring part.
