Chlorine tolerance aromatic polyamide membranes

Aromatic polyamide, another polymeric material used for seawater desalination, can tolerate a wider pH range from 5 to 9. However, aromatic polyamide membranes are known to be susceptible to chlorination in the presence of chlorine in water. [Pg.2324]

Membrane material. During the early days, membranes were usually made of cellulose acetate. At present, membranes can also be made from aromatic polyamide and thin-filmed polymer composites. Different membrane materials have their own distinctive characteristics, such as hydraulic resistance, pH range, temperature range, chlorine tolerance, and biodegradation tolerance. [Pg.235]
