Problems solved by technology

However, in existing applications, this method of silica removal requires complex and rigorous pretreatment procedures and is inefficient, leading to increased costs and thus uneconomical in some cases
In addition, sometimes due to the unforeseen fluctuations of the pretreatment system, the insoluble or partially soluble salts contained in the fluid, such as calcium sulfate or calcium carbonate, will be scaled or deposited in the desalination device
This is detrimental both for the removal of silica and for the desalination unit itself

Embodiment Construction

[0016] figure 1 A schematic diagram of one embodiment of a desalination system 10 of the present invention is shown. In this embodiment, the desalination system 10 includes an electrical separation device (Electrical Separation Device) 11 and a concentration device (Concentration Device) 12 in fluid communication with the electrical separation device. Figure 1 to Figure 5 The same reference numerals may indicate similar elements.

[0017] In the embodiment of the present invention, the electrical separation device 11 can be used to receive a first fluid (input fluid) 13 from a first fluid source (not shown) containing various substances and other impurities for desalination treatment. In a non-limiting example, the species contained in fluid 13 may include charged ions, such as magnesium ions (Mg 2+ ), calcium ions (Ca 2+ ), silicon dioxide (Silica), sodium ion (Na + ), chloride ion (Cl - ) and other ions. Thus, the output fluid (product fluid) 14 from the electrical se...

Abstract

The invention relates to a desalting system and method. The desalting system comprises a first electric separation device capable of receiving first fluid, performing desalting for the first fluid and receiving second fluid so as to remove ions coming from the first fluid. The pH value of the first fluid is larger than 7, and the pH value of the second fluid is smaller than 7.

Description

technical field [0001] The present invention relates to a desalination (Desalination) system and method for water recovery (Water Recovery), in particular to a method for removing silicon dioxide (Silica) contained in water by using an electrical separation (Electrical Separation or Electrochemical Separation, E-separation) device. ) for desalination systems and methods for water recovery. Background technique [0002] In industrial fields, large volumes of waste water, such as saline aqueous solutions, are produced. Usually, such waste water is not suitable for direct domestic or industrial use. In view of the limited availability of water resources, it is particularly important to recover acceptable usable water from fluids such as waste water, brackish water, seawater or other saline solutions. [0003] Silica is a common substance contained in natural water bodies. Due to its low solubility in water under normal conditions, many industrial process waters, such as boil...
