Abstract

Different modified agents were used to add hydrophilicity to low pressure thin film composite polyamide RO membrane and to confer anti-fouling properties. The technique of streaming potential measurement was used to evaluate the degree of modification of the membranes. Streaming potential along the membrane surface was measured. Where charged groups were present in the modified layer, the calculated zeta-potential values increased. This technique was used together with spectrum, flux and rejection measurements to define modification effect.
