FLOCCULANT COMPOSITIONS AND WATER TREATMENT METHOD USING THE SAME |
摘要 |
A flocculant composition comprises an aqueous solution of a mixture of titan yl sulfate or titanium tetrachloride with a water-soluble, neutral alkali or alkaline earth metal salt at a titanium to alkali or alkaline earth metal salt ratio calculated as TiO2 of from 0.25:1 to 0.0002: 1 by weight. The flocculant composition may further contain a water soluble ir on salt at a titanium to iron ratio calculated as TiO2 and Fe2O3 of from 1:1 to 40:1 by weight, or a water-soluble zirconium salt at a titani um to zirconium ratio calculated as TiO2 and ZrO2 of from 1:1 to 40:1 by weight, or a water soluble aluminum salt at a titanium to aluminu m ratio calculated as TiO2 and Al2O3 of from 1:1 to 40:1 by weight. A water-clarifying method comprises the addition of an aqueous solution of titanyl sulfate or titanium tetrachloride to raw water in combination with a water-soluble, neutral alkali or alkaline earth metal with or without further combination with a water soluble iron, zirconium or aluminum salt.
