Title: The Innovations of Bernard Capdeville in Water Treatment Technologies

Introduction

Bernard Capdeville, an innovative inventor based in Toulouse, France, has made significant contributions to water treatment technologies. With two patents to his name, he has focused on developing processes and materials that enhance the efficiency and effectiveness of water purification.

Latest Patents

Capdeville's latest patents include a novel process and reactor designed for water treatment using a granular bed. This process utilizes granular support materials with a volumic mass less than that of the water being treated. The operational procedure involves interrupting the withdrawal of treated water and stopping the feed of untreated water to allow the granular bed to float. Cleansing air is then introduced to agitate the floating bed, followed by the separation of materials based on their volumic mass, resulting in sedimentation and flotation. This innovative approach not only improves the treatment process but also enhances the separation of sediments effectively.

Another notable patent by Capdeville focuses on the production of granular materials specifically designed for water treatment. He developed a process that produces spherical granules composed of a thermoplastic polymeric matrix with a more dense adjuvant in the form of micro-grains. This unique design includes micro-cavities on the surface of the granules and cationic hydrophilic sites, leading to improved performance in water treatment applications. The production process involves mixing an oxidizable thermoplastic resin with a powdered adjuvant, followed by a series of heating, extrusion, and oxidation steps to create the final product.
