|
Fluoride (F) |
R/0 (Reverse Osmosis) |
|
Arsenic (As) |
R/0 (Most common) Other removal technologies are anion exchange, electrocoagulation, and membrane filtration by ultrafiltration or nanofiltration. Arsenic removal is also possible in the presence of adsorbents such as FeOOH (Iron(III) oxide-hydroxide), activated alumina, ferruginous manganese ore, granular activated carbon, or natural zeolites. |
