Abstract
PURPOSE: To improve precipitate concentrative property and dehydration characteristic and remove phosphoric acid efficiently by adding metal salt as well as metal oxide and/or metal hydroxide forming insoluble phosphoric acid compounds to phosphoric-acid-contg. liquid simultaneously or separately.
CONSTITUTION: Metal salt forming insoluble phosphoric acid compounds as well as metal oxide and/or metal hydroxide forming insoluble phosphoric acid compounds are added to phosphoric-acid-contg. liquid simultaneously or separately. Any metals such as aluminum salt, iron salt, calcium salt, and magnesium salt that can insolubilize phosphoric acid are usable as the metal salt to be added. Calcium, magnesium, etc. are usable as the metal oxide and hydroxide. There are particularly no limits for order of addition of the above-mentioned two, and they may be added either simultaneously or separately.
