Non-Standard PP Wound Filter Cartridges: Special Fluid Purification Filter Cartridges for Petrochemical Enterprises
PP wound filter cartridges are disposable filter elements suitable for pretreatment and security filtration in various scenarios. Their core advantages lie in their large dirt-holding capacity, low pressure drop, economical cost, and convenient replacement.
These cartridges use food-grade or industrial-grade polypropylene (PP) yarn, precisely wound onto a porous PP plastic or 304/316 stainless steel framework, forming a honeycomb-like deep filtration structure with a loose outer layer and a dense inner layer. During operation, liquid flows from the outside of the cartridge inwards; large particles are trapped in the outer layer, while smaller particles penetrate deeper for gradual filtration, achieving highly efficient deep filtration.
Key features include: non-toxic and odorless material, meeting FDA food-grade standards; excellent acid and alkali resistance and strong chemical stability; controllable filtration accuracy gradient and wide accuracy range to meet various filtration needs; non-renewable disposable cartridges, simple replacement; and economical cost, suitable for large-scale conventional filtration scenarios.
Typical applications are wide-ranging, covering pure water RO pretreatment, tap water and groundwater filtration, and can also be used for filtration of electroplating solutions, printed circuit board cleaning solutions, and industrial circulating water. It is also suitable for filtration of various media such as food and beverage, chemical fluids, and oils, and can be flexibly adjusted and adapted according to actual working conditions.
