WebJun 18, 2024 · A common variant on the gravity thickener design is the picket fence thickener. This technology is fitted with a stirrer comprising a series of relatively closely-spaced vertical arms, and is therefore similar in appearance to a picket fence. For both designs, the sludge enters the centre of a cylindrical tank and flows out to the periphery. WebMar 1, 1991 · If the design underflow concentration is 300kg/m3 for a thickener which is to be fed at a volumetric rate of 4m3/s and at a feed concentration of 5 kg/m3, a significant difference in the calculated vessel diameters using the three flux curve methods is obtained, as shown in Table 1.
