Title: Innovations by Richard M Ahlgren in Water Treatment Technologies

Introduction

Richard M Ahlgren is a notable inventor based in Waukesha, Wisconsin, recognized for his contributions to water treatment technologies. With a total of three patents to his name, Ahlgren has developed innovative solutions that address critical challenges in water purification processes.

Latest Patents

Among Ahlgren's latest patents is the "Ultrafiltration and electrodialysis method and apparatus." This invention features a combination of electrodialysis technique along with ultrafiltration membrane cell pairs, strategically interposed between a cation-selective membrane and an ion-nonselective membrane. The process involves feeding the solution to be treated to one side of the ultrafiltration membrane cell, while a concentrating solution is delivered between the two types of membranes. When an electric field is applied across the assembly, cations migrate through the ion-selective membrane, and weaker ionized substances pass through the ultrafiltration membrane which effectively filters out larger particles. Similarly, anions traverse through the ion-nonselective membrane, ensuring electrical balance within the system.

Another significant patent is the "Electrodialysis method," which pertains to deacidifying a feedstream. This process is defined by a first cell made up of anion-selective membranes alongside a pair of adjacent cells featuring both anion and cation-selective membranes. The solution to be treated enters the first membrane cell while a basic solution and a concentrating solution flow through the adjacent cells. The electric field applied across the system facilitates the transition of hydroxyl anions from the basic solution into the first cell, neutralizing acid hydrogen cations, while the acid anion moves into the adjacent cell, maintaining overall electrical balance.
