Title: Lee A Durham: Innovator in Fluid Treatment Technologies
Introduction
Lee A Durham is a notable inventor based in Oceanside, CA (US). He has made significant contributions to the field of fluid treatment technologies, holding a total of 2 patents. His innovative approaches have the potential to enhance the efficiency of fluid filtration and purification processes.
Latest Patents
One of Durham's latest patents is focused on the treatment of filter media to remove colloidal matter from fluid flows. This method involves adsorbing a coagulant onto finely divided filter media, which is then used to filter colloid-containing fluids. The coagulant is adsorbed while the filter is off-line, allowing for effective filtration without the need for continuous coagulant feeding during operation. The captured colloidal matter is subsequently removed during the backwashing process.
Another significant patent by Durham is a method and apparatus for measuring the fouling potential of membranes in reverse osmosis systems. This invention determines the optimal antifoulant concentration and cleaning interval by analyzing samples of liquid with varying antifoulant concentrations. The zeta potential of each sample is measured to identify the concentration that yields the most negative zeta potential, thus optimizing the cleaning frequency for the membranes.
