| titleOfInvention | Method for producing iron / aluminum composite flocculant |
| abstract | PROBLEM TO BE SOLVED: To provide a method for producing an iron / aluminum composite coagulant which has a strong coagulation action, has a high concentration, and has high storage stability and which can be obtained at low cost. SOLUTION: 1) The first method of reacting an aqueous solution of an iron salt and / or an aqueous solution of an aluminum salt with an aqueous solution of an alkali metal aluminate at a temperature of 20 ° C. or lower to precipitate an iron / aluminum hydroxide composite or aluminum hydroxide. Step, and then 2) a step of acidifying the system by adding an acidic substance and heating to dissolve the iron-aluminum hydroxide composite, and a second step of dissolving the iron-aluminum composite. A method for producing an iron / aluminum composite flocculant. The method for producing an iron / aluminum composite flocculant as described above, wherein the acidic substance is an aqueous iron salt solution and / or an aqueous aluminum salt solution. The method for producing an iron-aluminum composite flocculant as described above, wherein the ratio of iron to aluminum in the iron-aluminum composite is 3 or less as represented by Fe 2 O 3 / Al 2 O 3 . |
