A » Chlorine is never applied directly to polyamide reverse osmosis (RO) membranes because it can cause oxidative degradation of the membrane material. Polyamide membranes are sensitive to chlorine, and exposure can lead to irreversible damage, reducing the membrane's performance and lifespan. Therefore, chlorine must be carefully managed and removed from feed water, typically through dechlorination processes, before it reaches the membrane to ensure optimal functionality and longevity.

A »Chlorine is not applied directly to polyamide RO membranes because it can cause irreversible damage by oxidizing the membrane, leading to a loss of performance and lifespan. Polyamide membranes are sensitive to chlorine, so alternative disinfection methods or dechlorination steps are used to protect the membrane.
