What method of water treatment component is implemented during RO failure as part of the "Alternate Water Supply Plan"?

In the context of an "Alternate Water Supply Plan," the use of demineralization tanks during reverse osmosis (RO) failure is a critical strategy to ensure the continued provision of treated water. Demineralization tanks are designed to remove dissolved minerals and impurities from water, which is essential when RO systems fail, as these systems typically perform the primary function of removing such contaminants through membrane filtration.

When RO fails, reliance on demineralization tanks becomes crucial because they can effectively reduce the total dissolved solids (TDS) and other minerals present in the feed water. This helps maintain the water quality required for various applications, especially in settings like dialysis, where water purity is paramount.

The other methods, such as sand filters, activated carbon, and chlorination units, serve different roles within water treatment processes. Sand filters primarily remove suspended particles and turbidity, while activated carbon is best known for adsorbing organic contaminants and improving taste and odor. Chlorination units are used for disinfection to kill bacteria and pathogens, but they do not specifically address the mineral content removal like demineralization does. Therefore, in situations when reverse osmosis is not functioning, demineralization tanks play an essential role in continuing to supply water that
