Brine refining apparatus

摘要

An apparatus for refining brine including calcium and magnesium ions. Caustic alkali and carbonate alkali are added to the brine to produce a raw solution including flocks. The brine refining apparatus includes a settling tank having a supply of the raw solution for sinking the flocks to separate the flocks from the brine. A number of sheet members arranged in spaced-facing relation to each other within the settling tank. Each of the sheet members has a surface inclined at a predetermined angle with respect to a vertical plane crossing the corresponding sheet member.
