On the Properties and Mechanism of Alumino-Salt Flocculant

In this paper,reseraches have been performed on the flocculent properties and mechanism of flocculants such as AlCl₃、Al₂(SO₄)₃·18H₂O inorganic polyalumino-chloride,mixtures of AlCl₃ and high polymers PAM in the water with turbidity 2000.The electroconductivity,the viscosity and the size changes of floes in the process of flocculation have been measured.The results might serve as theoretical basis in designing flocculators and adopting alumino-salt flocculants.
