Severn Trent Services offers the Bayoxide® E33 and Bayoxide® E33P iron oxide adsorptive media for use with our SORB 33® arsenic removal systems in drinking water applications. In addition, the Bayoxide® E IN-20 media is offered for non-drinking water applications. Severn Trent Services recognizes that continuous improvement is essential. To this end, Severn Trent Services and our partner LANXESS are currently trialing new and improved versions of the already proven Bayoxide media variations.
