    arsenic removal Reading time: 12 minutes general Up until the year 2000, the European standard for drinking water was 50 µg · L –1 of As, a target that was within the reach of clarification or carbonate removal treatment in most cases Since this standard was modified (1998 European directive 98/83/CE), the limit has been lowered to 10 µg · L –1 of As, and this has led to theMost arsenic removal technologies are most effective in removing the pentavalent form of arsenic (As(V), arsenate), since the trivalent form (As(III), arsenite) is predominantly noncharged below pH 92 Thus arsenate is much less mobile than arsenite, as it tends to coprecipitate out with metallic cations or to adsorb onto solid surfaces Therefore, many treatment systems include anArsenic Removal Technologies | SSWM Find tools for
