Abstract

Disclosed are a plant-derived flocculant and a flocculant mixture having a higher flocculation capacity. The plant-derived flocculant comprises at least one of a dried matter of, a dried matter of, a dried matter of bananas, and a dried matter of; the plant-derived flocculant has a colloid equivalent of −1.5 mEq/g to −0.20 mEq/g, and the 2 weight % aqueous solution of the plant-derived flocculant has a viscosity of at least 6.0×10Pa·s (6.0 cP). The flocculant mixture of the invention comprises the plant-derived flocculant described above and a synthetic polymer flocculant having a colloid equivalent of −4.5 mEq/g to −1.2 mEq/g, whose 0.2 weight % aqueous solution has a viscosity of 1.3×10Pa·s to 4×10Pa·s (130 cP to 400 cP).
