description PURPOSE: To provide a flocculant/coagulant having flocculating/coagulating force of floating sludge or sludge and enhancing a sedimentation speed of those sludges. CONSTITUTION: A trivalent iron salt, two kinds of trivalent aluminum salts, an iron-containing alumina salt, a divalent magnesia salt and a divalent manganese salt are dissolved in water as base agents to form a soln. which is, in turn, adjusted to low pH by sulfuric acid or hydrochloric acid and oxidation and reduction between the respective base agents are reversibly kept. By adding the flocculant/coagulant thus formed to water containing sludge, hydrophobia reaction separating water molecules bonded to the peripheral surfaces of sludge particles to form bare particles is strongly generated and, succeedingly, coagulation reaction is generated to form flocs.
