摘要

透析用水的品質對病人的透析安全與長期預後有重大的影響，逆滲透膜是透析用水的設備中最重要的核心元件。隨著長期連續性地使用及前級處理維護不當，膜表面污垢沉積與生物膜孳生是影響水量和透析用水微生物品質的關鍵因素之一。本文從逆滲透膜工作原理、膜表面污垢形成原因及處理對策，並結合實例分享水處理逆滲透膜水量降低的處置經驗。闡述血液透析中心被忽視的事－逆滲透膜的清洗與消毒工作的重要性與必要性。

The quality of water used in hemodialysis seriously affects the safety and long-term prognosis of ESRD patients. Reverse osmosis (RO) membrane is the most important core component of water treatment apparatus for producing pure water. With lasting and continuous use of RO membrane and improper maintenance of pre-treatment of water treatment system, foulants' accumulation and biofilm growth onto the membrane surfaces and/or inside the membrane pores is one of the key factors affecting water production and microbial levels. This paper discusses the rationale of the reverse osmosis membrane, the causes of fouling on the membrane surface and the resolving solutions. This paper also combines examples to share our experience in dealing with the reduction of water production of the RO membrane. We explain the importance and necessity of cleaning and disinfection of RO membrane, which is often overlooked in hemodialysis centers.
