What is the actual effect of fluoride removal by water filtration equipment companies? If the fluorine content in the water is 1.2mg/L, the water is called superfluorinated water. If a person uses perfluorinated water, the body's bones and dental structures will be endangered, and at the same time, some other tissues will also be damaged. In order to prevent people from being harmed by fluoride in daily life, water filtration machines and equipment can be used to carry out fluoride removal, as these machines and equipment have strong fluoride removal practical effects.

The basic principle of fluoride removal by water filtration equipment is the same as removing other residues. RO reverse osmosis is a physical solution that only requires the diameter of the residue to exceed the diameter of the reverse osmosis membrane to be separated and removed. According to experimental measurements, fluoride ions can be removed, and the key separation target for reverse osmosis membranes is inorganic cations at 1nm or above.

The increased burden is in the opposite direction of the osmotic concentration and exceeds it, causing water in the concentrated solution to infiltrate in the opposite direction of the dilute solution. As the reasonable solution range of the reverse osmosis membrane is above 0.1nm, and the outer diameter of F-cations is 0.266nm, the use of reverse osmosis concentration can effectively remove fluoride ions from the saturated solution.

The removal rate of fluoride ions in 10mg/L water after reverse osmosis membrane is over 90%, while the allowable concentration of fluoride ions in drinking water of the European Community is 0.5-1.5mg/L, which should be lower in China. In recent years, with the improvement of RO reverse osmosis processing technology, RO reverse osmosis has reflected its advantages in terms of price.

Due to the fact that most of the fluoride ions in surface water come from the corrosion and dissolution effect of soft rocks, and there are also many soluble cations in the water, it is necessary to consider the harm of other molecular structures to the actual effect of fluoride removal when carrying out fluoride removal. When the salinity exceeds 5g/L, the removal rate sharply decreases. When the salinity exceeds 10g/L, the removal rate is only 82%. Therefore, the fluoride removal rate of surface water with high salinity using filtered water machinery and equipment is not too high. However, compared with other methods, the reverse osmosis method is simple to use and has a very good solution effect.
