Title: David A. Hopkin: Innovator in Desalination Technology

Introduction

David A. Hopkin is a notable inventor based in Victoria, Canada. He has made significant contributions to the field of desalination technology, holding 2 patents that focus on innovative methods for separating salt from seawater. His work is particularly relevant in addressing global water scarcity issues.

Latest Patents

One of his latest inventions is a centrifugal reverse-osmosis desalination unit incorporating an annular design. This apparatus is designed to separate an original feed solution, such as seawater, into a product solution of decreased concentration, which is relatively fresh water, and an exhaust solution of increased concentration. The system includes an annular reverse osmosis membrane contained within a pressure vessel that is housed in a rotor assembly. The rotor spins on an axle within an evacuated shroud, enhancing efficiency. The apparatus also features supply means for the original feed solution, exhaust means for removing the exhaust solution, and product removal means for extracting the product solution. The design allows for a combined radial and axial flow-path for the feed solution.

Another significant invention by Hopkin is a desalination apparatus that operates on the principle of reverse osmosis. This device effectively removes salt from seawater, separating it into a product solution with decreased salt concentration and an exhaust solution with increased concentration. The inclusion of an evacuated enclosure minimizes windage losses and reduces power consumption, making the apparatus more efficient.
