Product Introduction
1、 Basic attributes
Material: Dewatering Sediment Filter Bags are mostly made of polyester, polypropylene and other composite fibers, some of which contain anti-aging, acid and alkali resistant coatings, suitable for different working conditions;
Form: Bag like structure, common open/buckle design, size (diameter 10-30cm, length 30-100cm) and filtration accuracy (5-50 μ m) can be customized;
Adaptation scenarios: industrial dewatering followed by sediment filtration (such as chemical, environmental, mining), and can also be used for solid-liquid separation in small-scale laboratories.
2、 Core functions
Precise interception: By using a dense fiber structure, fine particles and impurities in the dehydrated precipitate are captured to prevent them from contaminating subsequent equipment or the environment with the filtrate;
Ensure process stability: reduce impurities blocking pipelines and valves, lower the probability of filtration system failures, and maintain continuous operation of the solid-liquid separation process.
3、 Main features
Strong durability: The material is tear resistant, wear-resistant, able to withstand friction from hard particles in sediment, and resistant to acid and alkali corrosion, with a long service life;
Easy to operate: The open design facilitates loading and replacement, and some styles come with handles, eliminating the need for additional tools and reducing downtime for bag replacement;
High flexibility: Multiple specifications and precision options are available, which can be matched with different models of filters and centrifuges to meet the filtration needs of different scales.
