摘要
The knowledge of properties of flocs produced in coagulation may enable one to reduce effects of their breakage in a treatment system. This is particularly important in treatment of water contaminated mainly with natural organic matter; produced flocs are fragile and susceptible to rupture. The purpose of the research was to determine the influence of a coagulant type on post-coagulation suspension strength. The results show that flocs produced based on prehydrolyzed coagulants are more resistant to breakage than those produced by a hydrolyzing coagulant. Strength of post-coagulation suspension increased with the increase of polynuclear Al species (Al-b species).
