  1. Is this for treating groundwater? We can successfully 'bind' arsenic in mine water with a 99% success rate. Our product is relatively cheap and can be used in a passive flow filter bed.

  2. As Derek mentioned, the species of As matters if you are opting to use conventional treatment methods. Commonly the use of Greensand regenerated with KMNO4 (+ small amount of chlorine up stream) will oxidize As III to As V (RO works better on As V than it does As III) so post treatment with RO to remove the As V is likely required.

  3. The technology for removal depends on the species of As you want to remove. As III (the un-oxidized version) requires different technology than As V. Most larger volumes applications oxidize the As to V using chlorine prior to treatment. The need to oxidize is generally determined by whether you are treating a using a large central system for distribution to multiple houses or whether treatment is for a single home or point of use?

  4. You may consider using Activated Alumina, which is effective for arsenic removal and for fluoride. It can also be regenerated quite  easily as well.
