Membrane Technology for Wastewater Treatment: A Detailed Report

This report provides a comprehensive overview of membrane technology in wastewater treatment. It begins with an executive summary highlighting the increasing demand for sustainable water resources and the development of membrane filtration techniques, particularly focusing on the use of polyvinylidene fluoride (PVDF) membranes due to their excellent properties. The report explores various membrane technologies, including reverse osmosis, nanofiltration, microfiltration, and ultrafiltration, detailing their applications in wastewater treatment and the removal of dissolved organic molecules. It delves into the characterization of feed properties, analysis and monitoring techniques, the general performance of ultrafiltration, and performance challenges in surface water and industrial wastewater treatment. Furthermore, it analyzes the causes and rate of fouling, the effects of membrane aging, and the quality of permeate, offering recommendations to extend the service life of PVDF membranes. The report also covers the impact of membrane characteristics, fouling performance, rejection performance, and feed salinity on permeate quality, concluding with key findings and references.
