String Wound Filter Cartridge

 

General description

String wound filter cartridge is a kind of deep filter element, which is used for fluid filtration with low viscosity and impurity content. It is made of textile fibers (polypropylene yarn, degreased cotton yarn, etc.) tightly wound on the porous core (polypropylene or stainless steel materials) according to a specific process. It has a dense honeycomb-like structure, which can remove suspended matter, particles, rust and other impurities in the fluid. It is widely used in the filtration of tap water, beverage, industrial water, domestic water, electroplating solution, chemical liquid, oil, paint, etc.

Application

  • Reverse osmosis pre-filtration
  • Pre-filtration for RO
  • Pure water filtration for electronic and power industry
  • Filtration in petroleum, chemical, mineral, and metallurgical industries
  • Industrial oil and organic solution filtration
  • Filtration in pharmaceutical, food and beverage industries
  • Filtration of reclaimed water reuse and desalination
