Title: Innovations by Gottfried Paffrath
Introduction
Gottfried Paffrath is a notable inventor based in Hohen Sulzen, Germany. He has made significant contributions to the field of waste management, particularly in the treatment of radioactive waste water. With a total of three patents to his name, Paffrath's work focuses on innovative methods that enhance the recovery and recycling of valuable materials from waste.
Latest Patents
Paffrath's latest patents include a method of treating radioactive waste water. This method involves concentrating radioactive waste water containing boric acid in an evaporator, to which an alkali is added to maintain a substantially neutral pH. The boric acid is then sedimented out by cooling the solution, and an acid is added to increase solids recovery by lowering the pH. The solid sediment is subsequently vacuum distilled to yield a moist powder. Another significant patent is the method of recovering boric acid from waste-water concentrates of nuclear facilities. This process treats waste-water concentrates containing boric acid, chemical residues, and radionuclides, especially from nuclear power plants, to recover boric acid for recycling. The practically neutral solution is acidified with selected acids to precipitate the boric acid, which is then separated and subjected to recrystallization for high purity.
