How to reduce the replacement period of the security filter element?

The general reasons for the frequent replacement of security filter cartridges are:

(1) The raw water quality is unstable and fluctuating frequently, resulting in excessive particulate matter entering the filter element, resulting in a shortened cycle;

(2) The pretreatment operation is poor, and the flocculant and scale inhibitor added by the pretreatment are incompatible 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 decrease in the effective filtration area of the filter element, resulting in replacement of the filter element. frequently;

(3) The quality of the filter element is not good, and the inner and outer apertures of the filter element with poor quality are basically the same. In fact, only the outer layer plays an intercepting role, and the filter element of the good filter element is gradually reduced from the outside to the inside, and the innermost layer has a filtering accuracy of 5±0.5. Μm, the amount of dirt is larger, and the long time used can ensure the quality of the effluent.

Measures to extend the life of the filter:

(1) The water source is generally a fixed source of water and cannot be easily changed;

(2) Improve the effect of pretreatment operation, optimize the dosage of flocculant and coagulant, select the scale inhibitor suitable for water source, adjust the pretreatment equipment to achieve the best operation state, and strictly follow the requirements of the operation regulations to ensure the pretreatment effluent quality. qualified;

(3) Selecting the brand filter with guaranteed quality can not only extend the life cycle of the filter, but also ensure the water quality of the security filter. For example, the Shengda filter has a filtration accuracy of 5±0.5μm. The new Shengda Purtrex filter with Z.Plex technology redefines all previous RO pretreatment performance and filter construction standards. Z.Plex technology uses short-diameter melt-blown filter elements, wide-layer spacing and a three-dimensional fiber matrix. The Purtrex filter element is particularly suitable for water treatment applications because fine sediment particles in water treatment applications can easily cause fouling of reverse osmosis equipment. This filter element is unmatched in retaining dirt in the water, with lower pressure loss and longer service life than most similar filters. Under the unloaded casing of the filter element, the fibers and the 3-dimensional network form a variety of pores, which can effectively capture impurities. In the next filter layer, Z.Plex technology's unique fiber structure has more and more small pores in the filter core, which can maximize the filter life and sludge removal efficiency.

For accurate micron-level filtration, the inner core is the last filter layer. The inner core is a hot melt bonded structure with unmatched integrity, downstream cleanliness and rigidity without the need for a support core. Similarly, the highly permeable bonded exterior coating is very smooth and prevents loose fiber movement, which is critical for applications where purity is critical.
