Title: Harold E Filter: Innovator in Ion Exchange Technologies
Introduction
Harold E Filter is a notable inventor based in Midland, MI (US), recognized for his contributions to the field of ion exchange technologies. He holds a total of 7 patents, showcasing his innovative approach to solving complex problems in chemical engineering.
Latest Patents
Among his latest patents, Harold has developed a method for the in situ solidification of ion exchange beads. This method encapsulates and solidifies spent ion exchange beads contained in a container, forming an ion exchange bed with a solidification resin without the need for external shear forces. The process allows the solidification resin to flow through the ion exchange bed by plug flow, effectively intermixing with and encapsulating each bead. Additionally, when free water is present, the process removes substantial portions of it while emulsifying and solidifying any remaining water in the bed.
Another significant patent involves a process for encapsulating radioactive organic liquids in a resin. This innovative method utilizes a cured resin system to encapsulate certain low-level radioactive wastes that are more soluble in water than in the uncured resin. The process includes diluting the waste with water to ensure that the amount of waste does not adversely affect the cure rate or physical properties of the final product. The aqueous solution is then uniformly dispersed in the curable resin system, which is cured to form a solid with the waste solution embedded within.
