摘要

本研究旨在研究TiO2纳米颗粒对医疗部门废水纳滤系统中使用的聚合物膜的渗透和截留性能的影响。研究了TiO2纳米粒子浓度对膜性能的影响。添加剂通常决定增强的膜性能，如渗透和保留能力。然而，由于纳米颗粒对水的亲和力，疏水性正在降低，这对渗透性能有重要影响，同时表面粗糙度也在降低，对污垢效应有重要影响。研究了具有四种不同浓度的TiO2纳米颗粒（从0到2%的纳米颗粒）的膜。结果表明，小百分比的纳米颗粒对膜的渗透性能有重要影响，发现在2%的纳米颗粒下，由于纳米颗粒聚集堵塞了孔，渗透性降低。

TiO2 Blended Membranes Used in Wastewater Nanofiltration Systems from Medical Sector

The study aims to investigate the influence of TiO2 nanoparticles on the permeation and retention properties of polymeric membranes used in wastewater nanofiltration systems from the medical sector. The research is focused on the influence of the TiO2 nanoparticles concentration on the membrane properties. Additives in general determine enhanced membrane properties like permeation and retention capacity. Hydrophobicityhowever, is decreasing due to the nanoparticles affinity for water and this have an important effect on the permeation properties, at the same time with the decrease in surface roughness, with an important influence on the fouling effect. Membranes with four different concentrations of TiO2 nanoparticles were studied, from 0 to 2% nanoparticles. Results showed that small percent of nanoparticles have an important impact on the permeation properties of the membranes, finding that at 2% nanoparticles the permeation decreases due to the nanoparticles aggregations which are blocking the pores.
