Zusammenfassung:To provide a liquid anionic flocculant where the use of a polyacrylamide-based flocculant can be avoided; treatment performance is kept in a liquid state; and long term preservation is possible, and which can be used in a place without facilities such as a powder feeding machine, a polymer flocculant dissolution device, and to provide a liquid anionic flocculant production method, a polysaccharide-containing anionic flocculant preservation method, and a treatment method using the liquid anionic flocculant.SOLUTION: In a liquid anionic flocculant containing a polysaccharide and an inorganic electrolyte, the ratio of xanthan gum in the polysaccharide is 5 mass% or more and the concentration of the inorganic electrolyte is 0.05 mol/L or more and less than 6.2 mol/L.SELECTED DRAWING: None 【課題】ポリアクリルアミド系の凝集剤の使用を避けることができ、液体状のまま処理性能を保ち、長期間保存することが可能であり、給粉機や高分子凝集剤の溶解装置といった設備が無いところでも使用することができる液体状アニオン性凝集剤及びその製造方法、多糖類を含有するアニオン性凝集剤の保存方法、並びに液体状アニオン性凝集剤を用いた処理方法の提供。【解決手段】多糖類と、無機電解質とを含む液体状アニオン性凝集剤であって、前記多糖類におけるキサンタンガムの割合が5質量%以上であり、前記無機電解質の濃度が、0.05mol/L以上6.2mol/L未満である液体状アニオン性凝集剤である。【選択図】なし
