.正渗透膜技术是一种新兴的膜技术，在海水淡化和废水回用方面具有潜在的应用前景。FO膜上的渗透压梯度用于产生水通量。在本研究中，系统地研究了并流错流膜系统的通量性能和污染物沉积在FO膜上。以海藻酸钠（SA）、牛血清白蛋白（BSA）和单宁酸（TA）为模型污染物。吸附在膜上的有机物通过振荡剥离，并通过傅里叶变换红外光谱（FTIR）和扫描电子显微镜（SEM）进行了表征。当初始通量为8.42L/m2 h时，对于含有BSA和TA的料液，通量降低和污垢沉积都很轻微。相比之下，通量降低和污垢沉积更严重的进料溶液中含有SA，作为一个独特的SA饼层上形成的膜表面上，并在膜污染中发挥了至关重要的作用。此外，随着FS中SA初始浓度的增加，膜饼层厚度显著增加，膜污染加剧。正向渗透（FO）中的有机污染：膜通量行为和污染物定量相互作用。
. Forward osmosis (FO) is an emerging membrane technology with potential applications in desalination and wastewater reclamation. The osmotic pressure gradient across the FO membrane is used to generate water flux. In this study, flux performance and foulant deposition on the FO membrane were systematically investigated with a co-current cross-flow membrane system. Sodium alginate (SA), bovine serum albumin (BSA) and tannic acid (TA) were used as model foulants. Organics adsorbed on the membrane were peeled off via oscillation and characterized by Fourier transform infrared (FTIR) spectroscopy and scanning electron microscopy (SEM). When an initial flux of 8.42 L/m 2 h was applied, both flux reduction and foulant deposition were slight for the feed solution containing BSA and TA. In comparison, flux reduction and foulant deposition were much more severe for the feed solution containing SA, as a distinct SA cake-layer was formed on the membrane surface and played a crucial role in membrane fouling. In addition, as the initial SA concentration increased in FS, the thickness of the cake-layer increased remarkably, and the membrane fouling became more severe.
