  • Xylem’s Leopold Oxelia is an ozone-enhanced biologically active filtration system and multi-barrier solution for municipal wastewater treatment. It combines ozone, filtration and analytical instrumentation to deliver optimal wastewater treatment for water reuse and discharge into sensitive waters. more
  • The Leopold Clari-DAF PW (Potable Water) system is a clarification technology for the pretreatment of rapid gravity filter feedwater. It is a proven, highly effective way to remove low-density particulates, as well as giardia and cryptosporidium. more
  • As part of the complete Leopold underdrain system, the I.M.S. 200 and I.M.S. 1000 media retainers increase flexibility in media design by eliminating up to 14 in. (35 cm) of support gravel. Their physically rigid construction reduces flexing of the slots and the chance of clogging or biofouling. more
  • The Leopold elimi-NITE 2.0 denitrification system harnesses the advantages of deep-bed mono-media filters to effectively and efficiently remove nitrate-nitrogen in wastewater effluent as well as suspended solids, including precipitated phosphorus. more
  • Leopold desalination pretreatment systems can significantly reduce membrane-fouling contaminants—color, organics, soluble metals, oil and algae—before they reach your reverse osmosis (RO) membranes. more
