Title:
高塩基性塩化アルミニウム
Document Type and Number:
Japanese Patent JP6845195
Kind Code:
B2
Abstract:
An aim of the invention is to provide highly alkaline aluminum chloride with basicity of 75%-95% and flocculant for water purification using it and to provide a flocculant that can reduce residual Al,reduce the number of particles, and lower the E260 value. A high alkaline aluminium chloride and a method for manufacturing the same are disclosed. The characteristic of the overbased aluminum chloride is that the composition is: M / Al2O3 (molar ratio) = 0.8 to 2.2 (M represents the number of moles of alkali metal), and E / Al2O3 (molar ratio) = 0 to 0.3 (E represents the number of moles of alkaline earth metals), Cl / Al2O3 (molar ratio) = 1.0 to 3.0, SO4 / Al2O3 (molar ratio) = 0 to 0.35 with the alkalinity being 75% to 95 %, and flocculant composition for water treatment, which contains 8% by weight to 12% by weight of overbased aluminum chloride in Al2O3 conversion.
