... the hydrophobic content of the copolymers can lead to reduced flux. Anionic modification and increasing molecular weight of the copolymers can also lead to reduced flux. Insufficient cleaning of anionic copolymers from the membrane leads to pH-dependent flux of deionized water during subsequent filtration. The pH...
