The system comprises two or more consecutively arranged thickening stages each consisting of one thickening tank or several parallel thickening tanks, and wherein the ratio of the largest inside diameter to the mean sludge level is larger than 1:1 in the first tank and smaller than 1:1 in the second tank relative to the direction of sludge flow.
