Product Introduction:
Filter Bags For Dewatering is a high-efficiency filtration product specially designed for solid-liquid separation. It is made using advanced technology and high-quality filter materials, such as high-strength materials like polyester fiber, and possesses excellent flexibility and durability. With a reasonable structure, the filter bag can ensure rapid water passage while effectively trapping solid particles under a certain pressure, thereby achieving efficient dehydration.
In addition, the edges of the filter bag are sealed using a hot-melt welding process, which avoids the leakage issue at the stitching of traditional filter bags. Moreover, the bag mouth is equipped with an elastic sealing ring or a flange interface, enabling quick connection with different types of dehydration equipment. This ensures no leakage or side seepage during the operation process, achieving the whole-process optimization from "rapid dehydration" to "precise filtration" and then to "stable operation".
