Zibo XiangRun Environment Engineering Co., Ltd.Some customers ask for water treatment by activated alumina in these days. We summarize below questions and answers in here.
1. The size:
The usual defluorinating activated alumina size is 1-2mm, 2-3mm, 3-5mm.
Yo2. The regeneration
You chould choose NaOH or aluminium sulfate. We see now aluminium sulfate is welcome. 1~4% Aluminium quantity is 60-80 times than defluorination.
3. The warranty of activated alumina.
It is for 3-5 year for normal use.
4. Hs Code of activated alumina
We usually use 2818.20.
5. Can you provide and advise the qty of AA required
In Fixed bed, thickness of activated alumina is 1.1 ~ 1.1 m, and the speed for 3 ~ 6 m/h. For Moving bed filter, thickness of activated alumina is 1.8 ~ 2.4 m, the speed 10 ~ 12 m/h.
6. The fluoride content after activated alumina defluorination.
less than 1ppm.
7.. Defluorination capacity?
2.5-5mgF/g
If there are any questions on defluorinating activated alumina, please let us know. Thanks a lot! About defluorinating activated alumina, the surface area, abrasion, bulk density, crushing strength are important specification.
