Wound and extruded cartridges for liquids

The liquid cartridges marketed by ICT FILTRATION are filter elements whose distinctive structure is based on winding or extruding threads of natural or synthetic fibres round a central supporting core. The type of thread used, the winding speed and the tension on the core determine the fine filtration grade.

Eco-efficiency


  • Maximum performance over a long life cycle.
  • Reduction and control of emissions.
  • Products meeting market standards.

Uses


The use of a cartridge in the process is based on the principle of filtration in depth, i.e. the contaminant is deposited inside, taking advantage of the large contact area with the threads that make up its structure. Like this the finest particles are retained inside the cartridge.
The main industrial applications and sectors using cartridges for liquid filtration include, among others:

  • Waste water treatment.
  • Surface treatment.
  • Seawater desalination.
  • Galvanic.
  • Chemical.
  • Petrochemical.
  • Hydroelectric.
  • Nuclear.
  • Food and drink.
  • Photography.
  • Electronics.

Qualities


The fabrics most commonly used to make cartridges for liquids are polypropylene, cotton and glass fibre, with cores made of polypropylene, stainless steel or zinc-plated steel.

The table refers to a 10″ polypropylene cartridge and a water temperature of 30ºC.
