What is the purpose of using high-efficiency fibers in the first step of desalination? Can high-efficiency fibers filter out some sodium ions?
That should be a strainer filter, used to remove any suspended particles that might pass through the multi-media filter. Ordinary filtration devices do not have the function of deionization; to remove ions, ion exchange resins with ion exchange capabilities are required, or electrodialysis or reverse osmosis membranes can be used.
This is to avoid the water treatment plants ahead claiming that the water is too dirty; generally, factories use their own water sources
1. The purpose of high-efficiency fiber filtration is to remove suspended solids (SS) as well as any oils that may be present, thereby pre-treating the raw water； 2. It has no effect on retaining or filtering calcium ions (except for transformed CaSO4 and CaCO3).
The diameter of the filter media ranges from a few micrometers to several dozen micrometers, and it can effectively remove suspended solids, bacteria, viruses, large molecular organic substances, etc., from water. The radius of sodium ions is 0.196 nm, and it cannot be removed. Additionally: Microfiltration: 0.1–10 μm – bacteria, coal ash, fermented cells, pigments, proteins, etc. Ultrafiltration: 0.005–0.1 μm – pigments, proteins, polysaccharides, macromolecules. Nanofiltration: 0.0005–0.005 μm oligosaccharides, dyes, polyvalent ions. Reverse osmosis: 0.0001--0.001μm electrolytes, organic solutes. Microfiltration, ultrafiltration, and nanofiltration also cannot remove sodium ions. Reverse osmosis, ion exchange resins, electrodialysis can
