Title: Zhiguo Wu: Innovator in Membrane Technology
Introduction
Zhiguo Wu is a prominent inventor based in Shanghai, China. He has made significant contributions to the field of membrane technology, particularly in the development of high-pressure spiral wound membrane modules. His innovative work has the potential to enhance water purification processes.
Latest Patents
Zhiguo Wu holds a patent for a high-pressure spiral wound membrane module. This module features a brackish water reverse osmosis (RO) or nanofiltration (NF) membrane combined with a permeate carrier. The design includes a narrow spacing between membrane contacting elements, which optimizes water permeability and salt diffusion rates. The membrane achieves a water permeability (A-Value) of at least 8*10 cm/s/bar at 25° C and a salt diffusion rate (B-Value) of at least 0.5*10 cm/s at the same temperature. The permeate carrier is designed with a density of 54 wales per inch or more, and a gap between adjacent ribs of 215 um or less. Water is fed to the module at high pressures, ranging from 50 bar to 120 bar, allowing for efficient retentate discharge at concentrations of 100 g/L, 130 g/L, or even 150 g/L or more.
