摘要
In order to inexpensively obtain a flocculating agent that uses brown algae, particularly brown algae due to be disposed of, as a starting material and that has a uniform aggregation capacity void of variation, a brown algae powder is obtained by treating brown algae with an acid aqueous solution, rinsing said brown algae treated with the acid aqueous solution in water, drying the rinsed brown algae, and grinding said dried brown algae into a powder form. Next, a flocculating agent is obtained by mixing a sodium compound powder with said brown algae powder that was ground into a powder form. The flocculating agent may be obtained by grinding the brown algae with the sodium compound already mixed therein. The flocculating agent comprises a mixed powder of the sodium compound powder and the dry brown algae powder treated with the acid aqueous solution, and the preferred ratio of the sodium compound powder included in said mixed powder is 5 to 10 wt%.
