Procedure

As another alternative, an aqueous solution containing 0.5 to 1.0 mole/L of calcium chloride and an aqueous solution containing 0.5 to 1.0 mole/L of magnesium sulfate are prepared. Each solution is passed through a millipore membrane filter for sterilization. The resulting two filtrates are mixed so that the ratio of the former filtrate to the latter filtrate roughly becomes 1:1 to 1:1.5. In the mixture, calcium chloride and magnesium sulfate react with each other to form a mixed solution of magnesium chloride and calcium sulfate. This mixed solution can be used as a sterilized coagulant.
