Introduction

David Stead is an accomplished inventor based in Lowell, MA (US). He has made significant contributions to the field of microfiltration technology, holding a total of 2 patents. His work focuses on developing advanced methods for creating hollow fiber microfiltration membranes, which are essential for various liquid filtration applications.

Latest Patents

David Stead's latest patents include a method of making and using a hollow fiber microfiltration membrane. This innovative membrane is created using a casting solution that consists of a fiber-forming polymer with a degree of polymerization greater than about 1000, a water-soluble polymer, an anhydride with about 2 to 12 carbon atoms, and a solvent. The process involves mixing and heating these components to form a viscous dope, which is then extruded through an annular orifice to create the hollow fiber microfiltration membrane. The membrane undergoes further processing through a coagulation bath and two leaching baths. This technology is particularly beneficial for filtering liquids such as wine and juice, effectively removing bacteria, gel, and solid particles.
