Is the polyether sulfone folding filter cartridge toxic and how to filter it
TANVI2024-08-27 TANVI421
Polyether sulfone (PES) folding filter cartridge is non-toxic under normal use. It is mainly composed of polyether sulfone membrane and other auxiliary materials (such as flow guide layer, end cap, shell, center rod, etc.), which have been strictly screened and processed to ensure their safety and stability.


The filtration principle of polyether sulfone folding filter cartridge:


Material characteristics: Polyether sulfone membrane is a material with excellent filtration performance, with uniform pore size distribution and high porosity, which can effectively intercept harmful substances such as small particles, bacteria, viruses, etc. in liquids.


Filtering mechanism:


Physical interception: Polyether sulfone membranes physically intercept impurities in liquids through their fine membrane structure, preventing them from entering downstream processes through the filter element.


Surface adsorption: Some impurities may adhere to the surface of the filter element due to electrostatic or other physical forces, and thus be further removed.


Folding design: The filter element adopts a folding design, greatly increasing the filtration area, improving filtration efficiency, and making the filter structure more compact, easy to install and replace.


The filtration process of polyether sulfone folding filter cartridge:


Pre treatment: Before filtration, it is usually necessary to pre treat the liquid to remove large particle impurities and suspended solids, in order to extend the service life of the filter element and improve the filtration effect.


Filtration: When the liquid passes through the polyether sulfone folding filter, impurities are intercepted by the filter and remain inside, while pure liquid flows out through the filter.


Flushing and testing: The filter element needs to be regularly flushed and tested during use to ensure its filtering performance and safety. During the production process, some filter cartridges will also undergo high-purity water flushing and integrity testing to ensure product quality.


Safety and Environmental Protection:


No chemical pollutants: The polyether sulfone folding filter cartridge does not add any chemical pollutants during the production process, and all parts are sealed using adhesive free hot melt welding technology, avoiding the introduction of chemical substances.


Environmentally friendly materials: The materials used in the filter element meet environmental requirements and are recyclable, reducing the impact on the environment.


Polyether sulfone folding filter cartridge is non-toxic under normal use and has excellent filtration performance and safety. It is widely used in various fields such as medicine, food, electronics, and chemical engineering, providing a reliable solution for liquid filtration.
