Abstract: Methods of performing targeted alpha therapy of a cancer patient utilizing actinium-225, methods of preparing a targeted alpha therapy drug that includes actinium-225, methods of preparing actinium-225 from radium-226, and methods of recovering radium-226 from an aqueous produced material stream generated from a natural resource extraction process. The methods of recovering radium-226 include separating the radium-226 from the produced material stream to generate recovered radium-226. The methods of preparing actinium-225 include converting the recovered radium-226 into actinium-225. The methods of preparing the targeted alpha therapy drug include incorporating the actinium-225 into the targeted alpha therapy drug. The methods of performing targeted alpha therapy include treating the cancer patient with the targeted alpha therapy drug.

Abstract: The invention provides methods and compositions for reducing the amount of water required in an industrial process, especially a bottling process such as beer or beverage manufacturing. The method comprising the steps of: collecting water used to rinse cleaned and/or dirty recycled bottles, spraying the collected water at a food contacting piece of equipment as part of a CIP rinse, and passing the CIP second rinse water into a cooling tower as make-up water. The method allows for the re-use of water already in the system but by being careful where each water stream goes the water does not accumulate contaminants that would damage the cooling tower or foul the bottled product or vessel that is cleaned by CIP method.

Abstract: Methods for recovering energy and water from at least one energy-rich process water stream are provided. The methods optionally incorporate the use of filtration, reverse osmosis, ion exchange, water softening, forward osmosis, and membrane distillation. The methods can be used to recover energy and water from blowdown or condensate from a water-containing industrial process, which in certain embodiments may be a boiler system.

Abstract: A composition and method of inhibiting scale formation and deposition from a feed stream passing through a membrane system is disclosed. The composition that is used to inhibit scale formation includes a composition containing an AA-AMPS copolymer and PMA.

Abstract: The invention provides methods and compositions for separating metals from a liquid medium, the method uses a copolymer derived from at least two monomers: acrylic-x and an alkylamine, wherein said polymer is modified to contain a functional group capable of scavenging one or more compositions containing one or more metals are disclosed. The treated liquid is then passed through a filtration system. The scavenging effect of the combination of the treatment with the filtration is unexpectedly greater than the sum of its parts.
