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 SR. Astonishingly, the desalination capabilities significantly improved, when the top, middle, and bottom layers simultaneously had 1, 0.1, and 0.1 wt.% of GOns, respectively. Overall, comparing the performances between the optimized sample containing low-dosage and without GOns demonstrated the PWF ameliorated from 6.68 to 20.36 L/m² h; also, the SR ability remained on an incremental basis as NaCl < MgCl₂ < MgSO₄ under 6 bar pressure. Manifestly, these authentic results denoted promising, innovative, and large-scaling insights when effectual PWF and SR be necessary.

水处理系统的膜组件面临代价高昂的损坏；因此，执行基于纳滤 (NF) 的预脱盐装置可以防止这些问题，并提高渗透水通量 (PWF) 和脱盐率 (SR)。因此，我们专注于通过“静电纺聚偏氟乙烯（PVDF）（作为底层）”，“通过静电纺PVDF生成中间层，电喷海藻酸钠后实现交联”来构建新型三元NF膜。和“通过界面聚合合成聚酰胺（作为顶层）”。更重要的是，它预计田口统计方法可以迅速优化氧化石墨烯纳米片 (GOns) 对水依赖性特性（如 PWF 和 SR）的影响。令人惊讶的是，当顶层、中层和底层同时分别具有 1、0.1 和 0.1 wt.% 的 GOns 时，脱盐能力显着提高。总体而言，比较含有低剂量和不含 GOns 的优化样品之间的性能表明 PWF 从 6.68 改善到 20.36 L/m² 小时；此外，在 6 bar 压力下，当 NaCl < MgCl ₂  < MgSO ₄时，SR 能力保持在递增的基础上。显然，当需要有效的 PWF 和 SR 时，这些真实的结果表明有希望、创新和大规模的洞察力。
