抗污染性能是最近几年水处理工业对反渗透膜提出的新要求,相对于传统的反渗透膜,抗污染反渗透膜的使用可以显著减少反渗透系统的化学药剂使用量和反冲洗频率,延长反渗透膜的使用寿命,节省系统的运行成本.主要介绍了目前市场上的商品化抗污染反渗透膜、相关制膜技术以及抗污染膜的研发趋势.
In recent years, water treatment puts forward the new requirement of low fouling for RO membrane, with relative to the conventional RO membrane, application of fouling-resistant membrane can significantly reduce chemical dosage and the frequency of RO system back washing, prolong the lifetime of RO membrane element and save operation cost. The current commercial fouling-resistant RO membrane in the market, related membrane technologies and its development trends are mainly introduced.
