Reasons for frequent replacement of PP filter element of water purifier

The quality of the PP filter element of the water purifier is not good. The inner and outer pores of the poor quality filter element are basically the same. In fact, only the outer layer plays an interception role. The filter pore diameter of the good water purifier PP filter element is gradually reduced from the outside to the inside, and the innermost layer is filtered. The accuracy is 5±0.5um, the dirt holding capacity is larger, and the long time used can ensure the qualified water quality.

The pretreatment operation effect is poor, the flocculants and scale inhibitors added in the pretreatment are not compatible with each other or do not match the water source, and the formed sticky substance adheres to the surface of the filter element, resulting in a reduction in the effective filtration area of the filter element and frequent replacement of the filter element;

The quality of raw water is unstable and fluctuates frequently, resulting in too much particulate matter entering the filter element and shortening the cycle.
