Latest Patents

One of his latest patents is related to electrochemical deionization. This invention involves an electrochemical cell designed for deionization, which utilizes electrochemical ion-exchange to effectively remove ions from a feed solution. Under the influence of an electric field, ions are adsorbed into, stored within, and pass through a permeable layer of particulate ion-absorbing material and binder. The design allows water from the feed solution to permeate through the layer, resulting in a concentrated solution of ions emerging from the rear of the layer. This cell operates without the need for separate sources of feed and eluant solutions, enabling continuous operation. In a modified version of the cell, the flow path for the feed solution passes through a highly porous ion exchanger structure, which enhances the absorption process, even in the absence of an electric field.

Another significant patent by Neville pertains to filter cleaning. This invention involves an electrically conducting filter medium that is cleaned in situ by applying brief voltage pulses between the medium and a counter electrode. The process liquid undergoes electrolysis during these cleaning intervals. The efficiency of the cleaning process is notably improved by occasionally applying a voltage of reverse polarity. For instance, a five-second cleaning pulse making the filter medium cathodic can be applied every quarter of an hour, with a reverse polarity pulse of similar duration applied every two hours. This innovative approach can significantly increase permeation rates.
