Title: Innovations by Inventor Hui Li
Introduction
Hui Li is an accomplished inventor based in Naperville, IL, with a remarkable portfolio of eight patents. His work primarily focuses on advancements in optical sensor technology and membrane filtration systems, contributing significantly to industrial processes.
Latest Patents
One of Hui Li's latest patents involves a linearized optical sensor calibration for measuring calcium concentrations in water samples. This innovative optical sensor can effectively measure calcium levels in various industrial water systems, such as cooling towers and boilers. By adding an indicator to the water sample, the sensor can form a complex that absorbs light. The absorbance profile of this complex can be non-linear across different calcium concentrations. However, Hui's method allows for the linearization of this profile, enabling calibration with just two solutions, thus simplifying the calibration process and reducing costs.
Another significant patent addresses the cleaning of pressure membrane systems using a water-in-air cleaning stream. This method enhances the performance of membrane filtration systems by controlling fouling, which can degrade filtration effectiveness over time. By supplying a feed stream that contains a greater volume of air than water, Hui's approach yields superior results compared to traditional methods.
