Abstract
In a method for extracting boric acid from boron solution, the boron solution is processed at a nanofiltration system, wherein the nanofiltration system generates a first permeate and a first concentrate. The first permeate is stored in a first storage tank. The first permeate is polished to generate a second permeate and a second concentrate. The second concentrate is stored in a second storage tank. The second concentrate is processed at a seawater processing system to generate a third concentrate and a third permeate, wherein the third concentrate comprises boric acid. The third concentrate is stored in a third storage tank.

A method for extracting boric acid from a boron solution, the method comprising:
- processing the boron solution using a nanofiltration system, wherein the nanofiltration system generates a first permeate and a first concentrate;
- storing the first permeate in a first storage tank;
- polishing the first permeate using the nanofiltration system to generate a second permeate and a second concentrate;
- storing the second concentrate in a second storage tank;
- processing the second concentrate at a seawater processing system to generate a third concentrate and a third permeate, wherein the third concentrate comprises boric acid;
- and
- storing the third concentrate in a third storage tank.
A method for extracting boric acid from a boron solution, the method comprising:
- processing the boron solution using a nanofiltration system, wherein the nanofiltration system generates a first permeate and a first concentrate;
- storing the first permeate in a first storage tank;
- adjusting a pH level of the first permeate in the first storage tank to achieve a predetermined pH level;
- polishing the first permeate using the nanofiltration system to generate a second permeate and a second concentrate;
- storing the second concentrate in a second storage tank;
- adjusting a pH level of the second concentrate in the second storage tank to achieve a predetermined pH level;
- processing the second concentrate at a seawater processing system to generate a third concentrate and a third permeate, wherein the third concentrate comprises boric acid;
- storing the third concentrate in a third storage tank;
- and
- distributing the first concentrate, the second permeate, and the third permeate to a source of feed water.
