Abstract

Ultrafiltration (UF) is increasingly used in the food industry and for wastewater treatment and water reuse. Knowledge of the membrane properties that stabilise during the initial period of module operation in an industrial plant is essential for design purposes. This paper presents the experimental tests carried out using a pilot plant with an industrial PCI B1 membrane module. The module was equipped with tubular FP100 (100 kDa) polyvinylidene fluoride (PVDF) membranes used to separate carwash wastewater. The effect of membrane compaction during the first few days of the process on changes in permeate flux and dextran (40-500 kDa) separation rate was investigated. The effect of fouling, membrane washing with P3 Ultrasill 11 solution (pH = 12) and maintenance with sodium metabisulfite solution on the stabilisation of the technological performance of the plant was determined.

摘要

超滤（UF）在食品工业以及废水处理和水回用中得到越来越广泛的应用。了解在工业装置中膜组件运行初期稳定的膜性能对于设计目的至关重要。本文介绍了使用配备工业PCI B1膜组件的中试装置进行的实验测试。该组件配备了用于分离洗车废水的管状FP100（100 kDa）聚偏氟乙烯（PVDF）膜。研究了过程开始几天内膜压实对渗透通量变化和葡聚糖（40 - 500 kDa）分离率的影响。确定了污垢、用P3 Ultrasill 11溶液（pH = 12）清洗膜以及用焦亚硫酸钠溶液进行维护对装置工艺性能稳定的影响。
