Abstract

Background

Membrane fouling is one of the major concerns associated with membrane processes.

Methods

A novel dome-shaped composite membrane using 3D printing technology and a flat membrane were fabricated. In addition to investigating the characteristics of the membranes, their fouling behavior was evaluated using the wastewater of automotive hoses washing and also sodium alginate (SA) in three different concentrations of 300, 500, and 700 ppm. Also, the membranes’ chemical cleaning was investigated using sodium dodecyl sulfate (SDS) and sodium hypochlorite (NaClO).

Significant findings

Fouling results at 700 ppm concentration of SA solution, which was the highest concentration in this study, revealed that the total fouling ratio (R_t) in the 1st cycle was obtained 26 % for the 3D composite membrane, while that for the flat membrane was calculated 53 %. The cleaning efficiencies for SDS and NaClO in the case of the flat membrane were nearly 89 %, while these values for the 3D composite membrane were almost equal to 100 %.

3D打印圆顶支架改善聚丙烯腈膜的污染行为

膜污染是与膜工艺相关的主要问题之一。方法采用3D打印技术制备了一种新型圆顶复合膜和一种平面复合膜。除了研究膜的特性外，还使用汽车软管洗涤废水和300、500和700 ppm三种不同浓度的海藻酸钠（SA）来评估膜的污染行为。同时研究了十二烷基硫酸钠（SDS）和次氯酸钠（NaClO）对膜的化学清洗效果。在本研究中最高浓度的SA溶液浓度为700 ppm时的污染结果表明，三维复合膜在第一个循环中的总污染率（Rt）为26%，而平面膜的总污染率为53%。在平面膜的情况下，SDS和NaClO的清洗效率接近89%，而3D复合膜的这些值几乎等于100%。
