Abstract
Official abstract text for this publication.
There is provided an efficient treatment method for boron-containing water capable of reducing an amount of use of medical agent and an amount of generation of sludge. A treatment method for boron-containing water of an embodiment includes a first process of concentrating boron-containing water to obtain boron-concentrated liquid. Further, the method includes a second process of making the boron-concentrated liquid to be brought into contact with a layered inorganic hydroxide, and making the layered inorganic hydroxide adsorb boron in the boron-concentrated liquid to remove boron.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for treating a treatment water containing boron, the method comprising: (I) concentrating a treatment water containing boron as an ion, to obtain a boron-concentrated water solution containing at least one of B 3 O 3 (OH) 4 − , B 5 O 6 (OH) 4 − , and B 3 O 3 (OH) 5 2− ; (II) contacting the boron-concentrated water solution with a layered inorganic hydroxide to adsorb said at least one of B 3 O 3 (OH) 4 ; B 5 O 6 (OH) 4 ; and B 3 O 3 (OH) 5…
