Abstract
Pharmaceutical water is a crucial component in drug manufacturing, as its quality directly affects drug safety and efficacy. This study focuses on membrane biofouling in pharmaceutical water systems during downtime, revealing its unique formation mechanisms: abrupt decreases in flow rate, reduced dissolved oxygen, and nutrient accumulation collectively create favourable conditions for microbial colonization. Biofilm formation not only causes a decline in membrane flux and an increase in transmembrane pressure but may also release harmful substances, such as endotoxins, posing a severe threat to water quality. The study systematically reviews existing control technologies, encompassing conventional methods such as chemical cleaning and backflushing, as well as innovative approaches including electrochemical treatment and cold atmospheric pressure plasma (CAP) technology. Furthermore, this paper prospectively explores future research directions, such as the development of green antifouling agents and the application of intelligent monitoring technologies, providing a scientific basis and technical support for achieving water safety and sustainable development in the pharmaceutical industry.
