The effect of porosity on filtration

Porosity refers to the percentage of the volume of pores in a bulk material to the total volume of the material in its natural state. For liquid filter bags, the porosity will directly affect the filtering effect. If the porosity is large, the filtering effect is usually not achieved. As a filter element, the filter bag is a key part of the filtration process. The quality of the filter bag determines the user’s filtering effect to a large extent. The filtering surface of the liquid filter bag filtrate is treated with special singeing, which not only effectively prevents the fiber from detaching from the contaminated filtrate, but also avoids the traditional rolling process from causing excessive clogging of the filter holes and shortening the life of the filter bag. All raw materials are natural white, without any special bleaching and dyeing treatment, fully complying with environmental protection standards. Because of the three-dimensional filter layer of the needle felt, when the liquid flows through the filter bag, the particles will stay on the inner wall surface and deep layer of the liquid filter bag due to the deep filtering mechanism. It has high trapping efficiency for solid or colloidal particles. The uniform thickness of the needle felt, stable opening rate and sufficient strength make the filter bag stable in efficiency and longer in use. The tightest sewing with five threads and double needles ensures that each liquid filter bag can achieve the best filtering protection. It has a wide range of applications and is suitable for liquid filtration in various industries.
