flux decline

Flux decline refers to the reduction in the rate at which water or other fluids pass through a filtration system over time. This happens because contaminants like dirt, minerals, or bacteria accumulate on the filter surface or within its pores, blocking the flow. As the filter becomes clogged, it becomes harder for liquids to pass through, resulting in decreased efficiency. Regular cleaning or replacement of the filter helps restore flow rates. Understanding flux decline is important for maintaining optimal filtration performance and ensuring system longevity.
