发明名称 Methods and compositions using lanthanum for removing phosphate from water
摘要 A partially soluble lanthanide compound and methods for use in removing phosphate from water. Preferably the compound is used in removing phosphate from water in swimming pools, spas, and similar structures. Alternatively, a combination of compounds having varying solubilities may be used to remove phosphate from water. Several water treatment techniques are disclosed, as well as a variety of different methods for delivery of the active ingredients. These delivery methods include use of a slurry of the active reagent in solution as well as a tablet, powder, or granulated structure. Additionally, the water treatment techniques may incorporate the use of a combination including both enzymatic compositions and compounds for phosphate removal.
