CELLULOSE ACETATE MEMBRANE FOR CONTAMINANTS REMOVING AND DESALINATION

Abstract

Membrane separation technologies, such as nanofiltration (NF), reverse osmosis (RO), and forward osmosis (FO), have gained great appeal as a sustainable and energy-saving method for seawater desalination and water purification. After years of development, polyamide composite membranes have become the main membrane materials for the above-mentioned membrane separation technologies. Recently, the reuse and treatment of discarded membrane components, as well as the pollution problem of polyamide composite membranes, have enabled some early membranes to regain certain application prospects. The most representative separation membrane is cellulose acetate (CA) membrane, which using a widely available and biodegradable environmentally friendly material, holds promising application prospects in water purification. Unlike aromatic polyamide composite membranes, CA-based membranes do not require complex detoxification processes after disposal, making them a sustainable alternative for water treatment applications. In this review, the history and the history and development of CA membrane are traced, the influence of Phase Inversion Parameters on CA Membrane Fabrication, and its potential applications are evaluated.
