Title: **Heinz Pfenninger: Innovator in Membrane Separation Technologies**
Introduction
Heinz Pfenninger is a notable inventor hailing from Lupsingen, Switzerland, with a remarkable portfolio of 7 patents. His innovative work primarily focuses on processes for treating aqueous fluids and the separation and purification of pigment suspensions, addressing significant challenges in chemical production and waste treatment.
Latest Patents
One of Pfenninger's groundbreaking patents details a method for treating aqueous fluids that contain organic compounds and salts of polyvalent inorganic acids, particularly sulfates. This process adjusts the pH of the solutions to below 4, concentrates the organic compounds through membrane treatment, and results in two distinct outputs: a concentrated aqueous retentate rich in organic compounds and an aqueous permeate that is nearly free of these compounds. This method not only facilitates easy disposal of concentrates but also allows the permeates to be further treated in wastewater plants.
Another patent from Pfenninger describes an innovative process for separating and purifying pigment suspensions. Utilizing a microfiltration unit equipped with semi-permeable membranes, this process allows for the consistent circulation of liquid through the membranes, gradually replacing permeate with washing liquid. This separation technique is particularly advantageous for processing fine pigment suspensions, which are commonly produced during pigment synthesis.
