Latest Patents

One of Sandmann's latest patents is titled "Process for filtering and encapsulating radioactive particles." This invention focuses on removing radioactive particles from waste or process water through a filtration process. The water is filtered using a medium composed of a thermoplastic organic polymer. The resulting filter cake is dried and transformed into a solid encapsulating medium through the application of heat and/or pressure. The filter medium is designed to be wettable by water but non-swelling, with a melting point ranging from 100°C to 300°C.

Another significant patent is "Filtration process using polyolefin fibrids as filter aids." In this process, a filter aid made from polyolefin fibrids, such as polyethylene or polypropylene, is added to aqueous suspensions of finely divided solid materials. This innovative approach enhances the filtration or clarification of these suspensions. The hydrophilic fibrids can also be used to precoat a filter medium, improving the overall efficiency of the filtration process.
