Fluoride in natural water is normally due to weathering or dissolution of fluoride containing minerals, mainly fluorite and fluorapatite.
The extent of the problem of the excessive fluoride in drinking water remains an important health issue. Strong base anion resins can removal fluoride from water.
It was found that the removal of fluoride was high at natural pH (7) and was improved for increasing contact time and adsorbent dosage.
Lanlang offers fluoride removal ion exchange resin the model is TA466D, it is Aluminum oxide based resin, specially for Fluorin removal.
There is advantage to fluoride removal ion exchange resin that we believe is worth mentioning.
In an R-O system, the fluoridated water is forced at high pressure through a membrane. The fluoride ions, with a sheath of water molecules, are too large to pass through the small pores in the membrane and only the water can get through. Thus virtually pure water is squeezed through the membrane.
By contrast, a negative exchange resin (which exchanges a hydroxyl ion for the fluoride ion). The distinct advantage of this system is that when it is saturated, ions will appear in the collected water, which will immediately and dramatically increase the electrical conductivity of the solution and thus be readily detectable by a very cheap monitoring system.
Another advantage of using IX resins is that it’s less wasteful of both energy and water than R-O.
