Abstract
Disclosed is a boron recovering device including: an aeration-type water-channel reactor including a water channel; at least one aeration unit disposed in the water channel and aerating a boron-containing solution by passing it through the water channel to deposit boron in the form of borax; and a precipitation bath precipitating the deposited borax in the boron-containing solution having passed through the aeration-type water-channel reactor and separating a filtrate by overflowing, a boron recovering device, a method of recovering boron, and a boron recovering system.
Claims3
A method of recovering boron, comprising:
- depositing boron included in a boron-containing solution in a form of borax by aerating the boron-containing solution;
- controlling a pH value of the boron-containing solution to reach a predetermined pH range by feeding an acid into the boron-containing solution, wherein the predetermined PH range is from about 7.5 to about 9.5;
- precipitating the borax in the boron-containing solution to separate the borax from a filtrate by overflowing the filtrate;
- and
- discharging, by a rotary dump valve, the borax from the precipitation bath.
