Abstract
The rheological characteristics of the wastewater sludge were investigated by using a Haake Rheostress RS 75
rheometer. The stress–sweep experiments and the small-amplitude-oscillatory-shearing (SAOS) tests were conducted.
The stress–sweep measurements demonstrate that addition of polymer coagulants to sludge samples could significantly
influence the corresponding complex shear modulus G*. Furthermore, the SAOS tests indicate that the sludge samples
treated with polymer coagulants will form more rigid structures. The original sludge samples mostly show typical
viscoelastic liquid-like behavior. However, the solid-like behaviors were always observed in the samples treated with
polymers.
