The use of ceramic membranes in the treatment and processing of various liquids, including those of organic origin, has increased tremendously at the industrial level. Apart from the selection of the most appropriate membrane materials and operational conditions, suitable membrane cleaning procedures are a must to minimize fouling and increase membrane lifespan. The review summarizes currently available and practiced non-reagent and cleaning-in-place methods for ceramic membranes that are used in the treatment of organic liquids, thus causing organic fouling. Backflushing, backwashing, and ultrasound represent the most often used physical methods for reversible fouling treatment. At the same time, the use of alkalis, e.g, sodium hydroxide, acids, or strong oxidants are recommended for cleaning of irreversible fouling treatment.
在工业层面，陶瓷膜在包括有机来源液体在内的各种液体的处理和加工中的应用大幅增加。除了选择最合适的膜材料和操作条件外，合适的膜清洗程序对于最大限度减少污垢和延长膜的使用寿命必不可少。本综述总结了目前用于处理有机液体从而导致有机污垢的陶瓷膜的非试剂和原位清洗方法。反冲洗、反洗和超声是最常用的用于可逆污垢处理的物理方法。同时，建议使用碱（如氢氧化钠）、酸或强氧化剂来清洗不可逆污垢。
