Embodiment 1
[0025] Double-membrane seawater desalination process specifically includes the following steps:
[0026] 1) Take shells aged for two years, which are easy to mine and obtain.
[0027] 2) Crushing the shells into 80 mesh particles.
[0028] 3) Add the crushed shells to the packed tower.
[0029] 4) Fully mix the raw water and carbon dioxide in the mixer. And adjust the pH value of carbon dioxide aqueous solution to 4.3. And use the flow sensor to monitor the flow of raw water.
[0030] 5) Add the carbon dioxide aqueous solution produced in step 4) to the packed tower. Using the acidity of the carbonic acid solution and the action of microorganisms, various minerals are precipitated from the ores and shells.
[0031] 6) The water produced in the packed tower in step 5 is added to the filter through the water delivery pipeline, and after entering the filter, the solid particles in the mineralized produced water can be removed and the turbidity can be reduced. And can use th...
Embodiment 2
[0036] Double-membrane seawater desalination process specifically includes the following steps:
[0037] 1) Take two-year-old shells, medical stone, wooden fish stone, and zeolite.
[0038] 2) Crush the ore in 1) into 60 mesh particles.
[0039] 3) Put the crushed ore into the packed tower.
[0040] 4) Add raw water and carbon dioxide into the mixer and mix thoroughly, and use a pH meter to adjust the pH value of the carbon dioxide aqueous solution to 4.0. And use the flow sensor to monitor the flow of raw water.
[0041] 5) Add the carbon dioxide aqueous solution produced in step 4) to the packed tower. Using the acidity of the carbonic acid solution and the action of microorganisms, various minerals are precipitated from the ores and shells.
[0042] 6) The water produced in the packed tower in step 5 is added to the filter through the water delivery pipeline, and after entering the filter, the solid particles in the mineralized produced water can be removed and the turb...
