Integrating graphene oxide into layers of PVDF/PVDF@cross-linked sodium alginate/polyamide membrane for efficiently enhancing desalination performances.

ABSTRACT: The membrane modules of the water treatment system are faced costly damages; thereby executing pre-desalination units based on Nanofiltration (NF) could prevent these suffers, and improve the permeated water flux (PWF) and salt rejection (SR). Hence, we focused on the construction of a novel ternary-layer NF membrane through "electrospinning Polyvinylidene Fluoride (PVDF) (as bottom layer)", "generating middle layer by electrospinning PVDF along with, the implementation cross-linking after electrospraying Sodium Alginate", and "synthesizing Polyamide (as top layer) through interfacial polymerization". More importantly, it anticipated that the Taguchi statistical method can expeditiously optimize the effects of Graphene Oxide nano-sheets (GOns) on water-dependent properties, such as PWF and
