3. Toxicological Information
Ingestion: No adverse effects expected
Skin contact: Not expected to be a skin irritant
Eye contact: No an eye irritant. No physical irritation

4. Mechanism
Defluoridation mechanism: The binding of fluoride ion to Ca2+ on NEWDEF®1  surface while OH- will be released

5. Defluoridation Capacity
The defluoridation capacity of NEWDEF®1  is about 1~4 mg/g which is higher than normal media in the same conditions. The capacity is changed by different raw water quality including fluoride concentration、temperature、co-existing ions etc..


6. Technical Advantages
Ø High capacity and shorter contact time
Ø Safety, no dissolution of toxic and hazardous substances
Ø High efficiency, NEWDEF®1 can remove 99% fluoride of the raw water. Thereby the treated water could be mixed with the raw water in order to reduce the operating costs and extend the operation cycle.
Ø Steady capacity under other ionic competition
Ø Lower regeneration cost and simple regeneration process
Ø Not only for fluoride removal but also can removal of iron and manganese.
7. Performance Comparison
Figure 1 and Figure 2 demonstrate that the NEWDEF®1  media have higher performance than other common defluoridation materials under the same conditions. The treated water volume of NEWDEF® is About 5.09—11.7 times of activated alumina and 12.9—23 times of activated clinoptilolite.
