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?
